Motor vehicle drivers may use the lane in certain circumstances such as to access parking or to turn at intersections or driveways. There may be situations where a contra-flow cycle lane could be used to provide for cycling on a route, for example on one-way streets where a bylaw allows this. (TSRGD limits maximum width of buffer zone to 1m). The paper established that education and enforcement options are unsuccessful in keeping kerbside cycle lanes free of parked vehicles. For design considerations and signs requirements, see the design guidance on provision for contra-flow cycling. This section demonstrates indicatively how the above guidance on cycle facility types, street types and width can be brought together to derive options for a range of circumstances. When using the table above, the following key width requirements of cycle lanes where no parking exists, are: Figures 2.11c and 2.11d in MOTSAM Part 1 [PDF, 2.3 MB] illustrate the general configuration of a cycle lane next to the kerb. Signs are not recommended and where the aim is to attract driver attention, coloured surfacing is preferable. Factors such as cycle flows, traffic speed and volume and the consistency and continuity of cycle infrastructure all need to be taken into account. This width is only acceptable where the mean traffic speed is no more than about 50 km/h, most parked vehicles are cars, and parking demand and turnover are low. This indicates that Road Controlling Authorities do not rely on the fact it is illegal to park in these locations, but instead use markings to reinforce this requirement. Refer to Section 4.8.3 of Austroads Guide to Road Design Part 3: Geometric Design (external link)for further information. Parking spaces should desirably be 2.0 m wide as per the table below. There are four green colours in use that are specified in AS 2700 S 1996. For narrower paths the risk of collision, and injury, will increase. So there should be a greater space between the path and the edge of the canal. Cycle lanes can accumulate debris due to reduced wind-sweeping effect from Darren is a member of the Institute of Advanced Motorists and the NZ Motoring Writers' Guild Table: Cycle lane widths next to parallel parking. Pavement specifications [PDF, 132 KB] for primary cycling routes including cycle-lanes and cycle-paths, shared paths and cycleways, as well as pavement shoulders where cycling demand is high and where a high level of service is desired, have been developed. 1 The conventional cycle lane is preferable to no facility at all, but it would be greatly improved by the provision of marked or physical buffers. The guideline could also be a useful in consultation and planning situations—if the guideline can't be met, then the path should not be built. * The minimum width of a cycle track is 1.50m. Table: Cycle lane clearance from angle parking, Clear space between parked vehicles and cycle lanes (m). COVID-19 SERVICES UPDATE: Information on Waka Kotahi services, SCAM ALERT: Vehicle licence (rego) renewal phishing emails, WAITANGI DAY – PLAN AHEAD: Heading away for the long weekend? Examples of bicycle-friendly sump grates are shown below. The minimum width of a cycle lane should be 0.875 m per lane. The maximum bicycle lane width in western guidelines is 2.5 m. This width is only acceptable where the mean traffic speed is no more than about 50 km/h, most parked vehicles are cars, and parking demand and turnover are low. However, there isn´t a unique standard for cycle … If this width is used the track should have soft kerb (preferably a compacted grass verge or a low kerb <0.05m on the left-hand side) which can be used by cyclists to take evasive action when passing or overtaking. A parking space width of 2.0 m should only be used if parked cars can easily park up against the kerb, with 1.9 m the absolute minimum width. Interpolation for different speeds is acceptable. I am an engineer, not a lawyer, but would think that whoever is responsible for such a route could be culpable after an accident if the guidelines have not been met. Hi all, I'm trying to challenge the local council (South Glos) on an issue to do with cycle facilites, and am being told that there is no room because the road lane widths are already near the minimum. It is suggested that the no-stopping lines could be maintained at a much longer maintenance interval than usual, for example 10 years, as due to their location on the carriageway within the cycle lane, the paint marking will seldom be driven over and as a result will be visible for much longer. When installing a cycle lane on an existing road care should be taken to ensure the crossfall of the section of carriageway within the cycle lane is acceptable particularly on roads with humped profiles such as those with dish channel and/or have been subject to multiple reseals. By Darren Cottingham. The minimum 1.5m cycle lane width is general guidance like most other highway design guidance. This implies when a cycle lane is marked on the left hand side of the road a cyclist should use it although there are exceptions such as if the cyclist is manoeuvring to turn right, or if the cyclist is using an adjacent shared path. Technical note 004 on buffered cycle lane design [PDF, 2 MB] gives guidance on the widths to be used for buffered cycle lanes. Two-way cycle tracks (also known as protected bike lanes, separated bikeways, and on-street bike paths) are physically separated cycle tracks that allow bicycle movement in both directions on one side of the road. This does not appear to be the case. Where there are poor surface conditions at the road edge, then the width of cycle lanes should be based on usable road space available to cyclists. The widths above do not take into account any other users of the towpath so there should also be additional space, separate from the path, where there are likely to be moored boats, at locks, so boaters operating the lock do not have to go onto the cycleway, and (dare I say it) for fishermen where fishing is permitted. Hence, sump designs with grates in a zigzag or wavy pattern to maximise flow rates whilst minimising the risk of bicycle wheels being caught are now available (see photos below). An allowance also needs to be made where ramps, that have been provided at vehicle access ways, or sumps extend into the cycle lane. Contra-flow cycle lanes may be provided on one-way streets. It also assumes that surface conditions adjacent to the gutter or road edge are of a high standard. In the Land Transport Rule: Traffic Control Devices (2004) a cycle lane is classified as a ‘special vehicle lane’. In general, most western agencies specify 1.2 m or 1.5 m as the minimum width for a bike lane and 1.5–2.5 m as the recommended width. Refer to MOTSAM Part 2, Section 2.10. If the roadway has a curb, this minimum width increases to 5 feet (1.5 m). This guidance applies to all streets in London and must be adhered to for relevant funding programmes. This treatment should only be applied in low speed and low volume environments, and where a suitable transition at each end of the street can be achieved. The absolute minimum width for a cycle lane plus parking should be 3.7 m. This width requires cyclists to ride close to the adjacent traffic lane to avoid potential collisions with car doors. These documents are for designers and decision-makers planning and delivering walking and cycling infrastructure. ], The guideline could also be a useful in consultation and planning situations, Skipton Swing Bridge to be replaced in May, Canal & River Trust launch campaign for volunteers, London moorings suspended for Eco Zone use only, Minimum widths for combined cycle and pedestrian routes. Maximum total width: 12m. Check our holiday journeys tool(external link), CNG Home | Site map | Planning | Designing | Evaluating and monitoring | Trials | Case studies. The type of kerb and how it connects with the road surface is an important consideration when measuring the useable cycle lane width (see Concept design considerations, above). The recommendations above are intended to provide a reasonable level of risk to all users. Angle parking is appropriate only where the speed limit is 50 km/h or less. If the road lane and the bicycle lane are placed together, the width of the combined lanes should be no greater than 14 feet. It can be found on the internet by searching TA 90/05, and is quite easy to understand. lane (minimum width of 4m) enables drivers of all motor vehicles to overtake cyclists with an acceptable clearance. The latter two having some yellow pigment, remain green under sodium lights. For towpaths I would assume 3 metres might be acceptable for rural paths used mainly for recreational use (not including time trials! A minimum width of 1.8 m should be provided, with a total minimum width of 4.3 m between the curb and the outer edge of the cycle lane. A road controlling authority must, at the start of every special vehicle lane and after each intersection along its length, mark on the road surface a white symbol defining the class or classes of vehicle for which the lane has been reserved. Details of Target, Desirable Minimum and Absolute Minimum widths for various types of cycle link facilities are shown in 5and arranged in descending order of highway width required in 6. Crossfall is the slope of the surface of a carriageway measured perpendicular to the road centreline. Examples of where coloured surfacing is recommended are shown below. Lane widths of 10 feet are appropriate in urban areas and have a positive impact on a … We recommend referring to all of these documents. Figure 46: Cycle lane between traffic lanes (St Lukes, Akl) Designers should be aware that while highly useful to confident cyclists, cycle lanes between traffic lanes are often unattractive for less confident cyclists or in areas with reputations for poor driving behaviour. However, this is not always possible depending on surface drainage and stormwater considerations. Buffered cycle lanes are conventional cycle lanes with a painted buffer space separating the cycle lane from the adjacent parking and / or general traffic lane. THE Department of Transport (DoT) have issued a guideline for the design of paths for cyclists and pedestrians as part of road construction projects, writes Paul Robinson. Examples of recently installed buffered cycle lanes in New Zealand are shown below. The speed limit is used unless the 85th percentile speed is significantly higher. Cycle lanes should be a suitable distance away from angle parking to encourage cycling in a position that aids visibility between drivers and cyclists and allows cyclists to avoid vehicles that are emerging from a car parking space. If cycle traffic flows exceed 150 in the peak hour, then sufficient width to accommodate overtaking manoeuvres should be considered. A cycle lane wider than 2.5 m is not recommended as it can be mistaken for a traffic lane. I have also had a quick look at the requirements in other countries, which are pretty much in line with the above. If a kerbside cycle lane is retrofitted, then a no-stopping line will exist for some length of the new cycle lane, whilst other parts of the cycle lane will not have this marking if the Road Controlling Authority does not add it. When dealing with existing streets, lanes, cul-de-sacs, motorways, dual carriageways and other types of roads, the tendency is to keep the original width unless it needs to be widened to allow more traffic to pass or to improve safety (e.g. Traditional cycle lanes are painted lanes within the carriageway that are suitable for enthused and confident cyclists. When greater than 2.5 m of space exists between the kerb and edge line, painted/flush diagonal bars should be provided in the rightmost part of the cycle lane to suggest a cycling area of between 1.5 m and 2.0 m in width, and to separate the cycling area from the general traffic lane. These are G13 Emerald, G16 Traffic Green, G26 Apple Green and G31 Verdigris. However, in practice, several road controlling authorities who have historically marked cycle lanes without no-stopping lines have found this to be insufficient. When using the table, the following key width requirements of cycle lanes next to parking exists, are: Figures 2.11 c and 2.11d in MOTSAM Part 2 [PDF, 2.3 MB] illustrate the general configuration of a cycle lane next to parking. Standard wobble is already built into the values in the table. Where a cycle lane exceeds 3.0m in width, there may be some confusion with traffic lanes and a cycle track may be a better solution. This width does not include the road gutter section. Having a mixture of some kerbside cycle lanes with, and some without no-stopping lines in the same district should be avoided. In a cycle track the minimum width should be 1.0 m per lane. Minimum cycle lane width 1.5 m 1.9 m . Similarly, where mean vehicle speed is 70 km/h, the absolute minimum combined width of cycle lane and parking should be 4.2 m. Cycle lane width should be between 1.5 m and 2.0 m. The provision of kerbed projections or other treatments including channelisation are important in locations next to parking (especially angle parking) when motor vehicle drivers might drive in a parking area when parking demand is light. Also check the guidance provided by the road controlling authority for the area in which you designing, as their minimum requirements may exceed those outlined below. 4.4.3 Street profiles. Minimum flush median width: 1.5m. Roads might be widened to be standardised when they are resurfaced or realigned.The widest section of ‘road’ in Britain is most likely the 17 lanes on the M61 at … A modern Autobahn divided highway with two lanes per direction has lanes 3.75 m (148 in) wide with an additional clearance of 0.50 m (20 in) on each side; with three lanes per direction this becomes 3.75 m (148 in) for the rightmost lane and 3.5 m (140 in) for the other lanes. The absolute minimum general traffic lane width is 3.0m on roads subject to a 30mph speed limit. We've pulled together a collection of high-quality UK design guidance for walking and cycling infrastructure. Detailed advice on surface tolerances is provided in Austroads Guide to Road Design Part 6A(external link) . It is useful for highlighting the start of a facility and transitions between different types of cycle facility (eg from an on-road cycle lane to an off-road path). Table: Cycle Lane widths next to kerb or road edge or between traffic lanes. They are grouped into themes, including nation-specific guidance. They should be installed immediately to the left of the cycle lanes at the start of the facility and at frequent intervals to limit the incidence of motor vehicles travelling over, or to the left of, the cycle lane. The legal gap between cyclist and passing vehicle is also 1 metre. ‘Y’’ distances will be determined by the type and speed of the road environment. Therefore they should be established by local bylaw; this is particularly important for contra-flow cycle lanes that oppose the normally permitted direction of traffic. 1.Minimum cycle lane width must be: 1m - 50km/h or less 1.5m - 60km/h or more 2.A minimum cycle lane width of 1.5m is required if the temporary cycle lane is uphill 3.Cones are required on edge of temporary lane opposite closure if road is not well defined 4. It is most applicable when speeds are below 40 km/h. The requirements for delineating cycle lanes, use of the cycle symbol and marking of no stopping lines in cycle lanes, are provided in MOTSAM Part 2, Section 2.10 [PDF, 2.3 MB]. Where kerb extensions are provided to ensure sufficient intervisibility, but result in insufficient cycle lane width, more upstream parking could be removed or the general traffic lane narrowed. Cycle lanes next to parking should be installed in accordance with the details shown in the table and its associated notes. It is important that the cycle lane is not terminated prior to the kerb extension and that a taper of not less than 1 in 30 is achieved for the cycle lane where it tapers from a kerbside alignment. This lack of consistency may be confusing for some drivers. A lane runs perpendicular to a road $64 ft$ wide. Previous trials have provided some insight into the style of buffer markings that are more likely to be successful. I am unable to understand what properties should hold for the pole to make its way into the lane. One-way cycle track Two-way cycle track Peak-hour volume in width of cycle-track (m) peak-hour volume in width of cycle-track (m) The width of cycle lanes varies depending on matters such as whether or not parking is provided, parking turnover rates, road gradient, speed and volume of motor vehicle traffic, the ability to make road space available given the needs of other road users, and physical constraints. The first two are blue-green and become dark under yellow sodium street lighting. by creating a hard shoulder). A two-way cycle track may be configured as a protected cycle track—at street level with a parking lane or other barrier between the cy… Therefore the minimum width of the lane required for a large vehicle with a bicycle is 4.7 metres, not 4.2 metres. permits, the cycle lane could be taken outside parked vehicles using a 1m wide buffer zone (0.5m minimum) between the parking spaces and the cycle lane. There is a safety risk associated with vehicles parking in cycle lanes as this can result in people on bikes being required to travel out of the cycle lane into the general traffic lane in order to pass parked vehicles. For example, the Road User Rule stipulates that a driver must not stop, stand or park a vehicle within 6 m of an intersection, within 6 m of the driver’s approach to a pedestrian crossing, within 6 m of a bus stop sign, or within 500 mm of a fire hydrant (Road User Rule, Clause 6.4–6.10(external link)). Lanes should be coloured green and marked with standard cycle pavement symbols to enhance their visibility. • Posted speeds are greater than 40 miles per hour, the minimum bike lane should be 6 feet, or However, these locations are commonly marked by no-stopping lines, or other markings, to reinforce what the Road User Rule requires. 301.2 Class II Bikeway (Bike Lane) Lane Width …The minimum Class II bike lane width shall be 4 feet, except where: • Adjacent to on-street parking, the minimum bike lane should be 5 feet. In both cases there should be some form of segregation, such as a white line, between cyclists and pedestrians. Detailed guidance on lighting design is available in the M30 Specification and guidelines for road lighting design. In the meantime, best practice guidance is provided below. We are most interested in the width required. Comprehensively revised and updated in 2014, LCDS sets out requirements and advice for cycle network planning and for the design of dedicated cycle infrastructure, cycle-friendly streets and cycle parking. It is suggested that the same applies to kerbside cycle lanes; without the no-stopping lines, compliance with the no-stopping restriction tends to be poor. The Road User Rule does not require cyclists to use a marked cycle lane when one is provided. If a 4m lane width cannot be achieved then, according to advice given in TAL 15/99 Cyclists at Roadworks (1999), a ‘narrow’ lane width of up to 3.25m to 3.50m will enable If not, it is strongly advised to provide street lighting on key cycle routes. Refer to MOTSAM Part 2, Figure 4.4 [PDF, 2.3 MB] for recommended cycle lane layouts at a typical pedestrian crossing with kerb extensions, although advanced stop lines (ASL) should be included. Cycle lanes next to the kerb or road edge should be implemented in accordance with the details shown in the table below and its associated notes. Many people prefer to avoid hills when cycling. Where the buses are more frequent, alternatives such as taking the cycle facility off road or indenting the bus stop should be considered. Therefore, where a steep uphill gradient is unavoidable, additional width should be provided to allow for this characteristic. Lane width (m) C l (m) 3.0 0.6 3.2 0.7 3.5 0.8 3.7+ 0.9 Sealed shoulders When adjacent to sealed shoulders, the lateral clearance to an edge line(on the inside of a curve) may be reduced to zero as long as the minimum lateral clearance is available in the sealed shoulder width and the shoulder is not used for parking or on-road cyclists. 8.5 Width requirements .....42 8.6 Crossfall, camber and drainage ..........................................................................................43 8.7 Gradients … However, the side clearance required is about 0.53 m, on both side and 1.06 m in the center. Check whether cycle lanes are a suitable facility for your target users and for the type of road. Width requirements ..... 40 Pedestrian and cycle flows........................................................................................................... 44 Provision alongside carriageways ................................................................................................ 45 In addition there should be at least 0.5 metres 'verge' between the edge of the path and the fence. An ASL as per a normal intersection configuration should be used. Two-way cycle tracks share some of the same design characteristics as one-way tracks, but may require additional considerations at driveway and side-street crossings. Wider parking lanes should be provided on roads with steep camber, or on curved sections (where parking next to the kerb is difficult), where there is excess road space available or where heavy vehicle parking is common. The guideline also says 'Where a path is adjacent to hazards such as a ditch (or other water feature) a greater separation should be considered to minimise the risks'. Minimum shoulder if used as a cycle lane: 1.2m. Whilst the definition of a cycle lane as a special vehicle lane means in theory it is not necessary to mark no-stopping lines in cycle lanes, this situation can be compared to other locations where the Road User Rule prohibits parking. Green coloured surfacing should be used at locations where motorists may be unaware of the likely presence of cyclists, or where motorists are likely to cross over the path of cyclists (for example at intersection transitions or across side streets). The guideline is called 'The Geometric Design of Pedestrian, Cycle and Equestrian Routes—TA 90/05'. The cycle lane width should also be considered in the context of the width of the adjacent traffic lane and combined widths of less than 4.6 m avoided. A well-defined line is required at the side adjacent to vehicle parking, so that drivers do not consider the buffer as an extension of the parking zone. A motor vehicle driver must not drive in a marked cycle lane unless the size of their vehicle or load or the presence of a road obstruction means it is impractical to stay outside the cycle lane, and driving in the cycle lane can be done safely and without impeding other traffic(external link). Drainage/sump grates are of particular concern as a bicycle wheel may get caught between the bars of the grate or any gap between the edge of the grate and the road surface. Case study: Dunedin cycle lane marking trial evaluation [PDF, 4.2 MB], Case study: Green cycle lane line markings, Hastings, © 2021 Waka Kotahi NZ Transport Agency, all rights reserved, Land Transport Rule Traffic Control Devices 2004 definition, Vehicle licence (rego) renewal phishing emails, A cycle lane means a longitudinal strip within a roadway designed for the passage of cycle.’, Figures 2.11 c and 2.11d in MOTSAM Part 2, Technical note 004 on buffered cycle lane design, Austroads Guide to Road Design Part 3: Geometric Design, Broken Yellow Lines in Kerbside Cycle Lanes, width (see Concept design considerations, above), Case study: Dunedin cycle lane marking trial evaluation, The purpose is to cross the cycle lane to make a turn, leave a road, enter a marked lane or line of traffic from the side of the road or another marked lane, or to park in a place clear of a special vehicle lane; or to enter a stopping place or loading zone to pick up or drop off passengers or a load; and, The driver drives in the lane for the minimum length necessary to complete the manoeuvre and for no more than a maximum length of 50m; and, The driver gives way to vehicles entitled to use the lane. The absolute minimum width for a cycle lane plus parking should be 3.7 m. This width requires cyclists to ride close to the adjacent traffic lane to avoid potential collisions with car doors. The maximum permissible width of a vehicle is 2.44 and the desirable side clearance for single lane traffic is 0.68 m. This require minimum of lane width of 3.75 m for a single lane road. Low use (rural): 3.0 metres pathway plus at least 0.5 metre 'verge' each side plus width for other users. Buffered cycle lanes involve a painted buffer between the cycle lane and general traffic lane, plus some form of offset to any adjacent parking, and are an alternative option to separated cycleways. Where ‘reverse-in’ parking is used, the minimum clear space should be 1.0 m. High use (commuter cycling) : 5.0 metres pathway plu 'verge' plus width for other users. Even more so, having some parts of a kerbside cycle lane with no-stopping lines and other parts of the same cycle lane without no-stopping lines sends confusing messages to drivers. Typical buses and large trucks are 2.7 metres wide (including mirrors). The Transport Agency is willing to work with road controlling authorities that would like to use this type of cycle lane in an innovative way. Cycle lanes marked adjacent to the kerb are not legally required to have no-stopping lines. ‘A cycle lane means a longitudinal strip within a roadway designed for the passage of cycle.’(external link). Although there is not a specific legal requirement to use the above guideline for towpaths, legislation reqires all organisations which build combined cycle/pedestrian routes to do so safely. A bus stop used for ‘layover’ must not be provided within a kerbside cycle lane. [Paul was a road designer and ended as a safety engineer doing risk assessments for all kinds of potentially dangerous systems. The table below provides a simplified means of determining the actual width required for cycle lanes and tracks. If it is just possible to carry a pole $125 ft$ long from the road into the lane, keeping it horizontal, then what should be the minimum width of the lane? Clause 2.1(1) states, however, that a driver (note that the definition of ‘driver’ includes cyclists) must at all times drive as near as practicable to the left side of the road. Lane width is one of the most important aspects to consider when designing cycle lanes. When climbing steep hills, experienced cyclists tend to work the bicycle from side to side and less experienced cyclists tend to wobble. Major truck or transit routes through urban areas may require the use of wider lane widths. Surfacing, grates and other considerations. grass or hard shoulder), then. Where the combined width of parking space and cycle lane is limited, the parking space should be kept narrow, so that good parking discipline is encouraged, allowing people on bikes to avoid opening car doors. Note also that the common practice of marking no-stopping lines within 6 m of an intersection (despite the fact that this is not necessary under the Road User Rule) may cause other problems. The width of the motorcycle lane is too narrow for bigger motorcycles, as well as for the purpose of overtaking. When it is not possible to achieve a wider cycle lane and the adjacent edge is a kerb, then, When it is not possible to achieve a wider cycle lane and the adjacent edge is transversable (e.g. recommends a traffic lane width of 3.7m (12 ft) specifically for highways and expressways, whereas the American Association of State Highway and Transportation Officials (AASHTO), in its guide entitled A Policy on Geometric Design of Highways and Streets (the “Green Book”), recommends a lane width of 3.6m (12 ft) (AASHTO, 2011). It can be found on the internet by searching TA 90/05, and is quite easy to understand. This distance may be reduced to 2.4m and to 1.0m as an absolute minimum where cycle approach speeds are low and the approach geometry encourages a reduction in speed on the traffic-free route. Surfaces should match up with existing features such as pit covers, edgings or driveways to within 5 mm.
