T.P.D.M. V.2.3<br />

(Al/2001)<br />

3.8.3.9 Normally when a cycle track follows a main carriageway route any footway will be<br />

positioned at the rear of the verge/cycle track/footway area. However if there are bus stops<br />

along the route arrangements will need to be made to enable pedestrians to wait adjacent to<br />

the carriageway. Such waiting areas must be sufficiently wide to avoid pedestrians<br />

encroaching onto the cycle track or the adjacent carriageway. Points at which pedestrians<br />

are required to cross the cycle track in the vicinity of bus stops should be properly defined,<br />

with railings being used to prevent them crossing elsewhere. Appropriate signs and<br />

markings for these situations are shown in Volume 3. Where cycle and pedestrian traffic in<br />

these areas is heavy it may be safer to terminate the cycle track and instruct cyclists to<br />

dismount.<br />

3.8.3.10 At main road junctions where there are joint pedestrian and cycle crossing facilities it is<br />

preferable that cycle tracks be terminated prior to the junction and cyclists be instructed to<br />

dismount with proper 'Dismount 5 sign. This is particularly relevant where pedestrian and<br />

cycle flows are high. Pedestrians should never be put in a position where they may be<br />

trapped on the carriageway after having crossed the road because of the volume of cycles.<br />

Adequate reservoir space for waiting pedestrians and cyclists must be provided. Any refuge<br />

islands must be at least 2m wide in order that a cyclist can wait without the cycle protruding<br />

onto the carriageway.<br />

3.8.3.11 Cyclists on cycle tracks should have a clear view ahead for a distance of preferably 25m but<br />

never less than 15m. Adequate sight lines must be provided for both pedestrians and<br />

cyclists where these are likely to intersect and in some instances railings may be necessary<br />

to prevent pedestrians stepping into the paths of cyclists when emerging from a side path or<br />

at the foot of steps. Care should be taken in the vicinity of pedestrian/cycle crossing points<br />

that street furniture, including any trees, does not interfere with the sight lines of pedestrians<br />

or cyclists.<br />

3.8.3.12 Horizontal and vertical clearances should be in accordance with section 3.5.<br />

3.8.3.13 An integral part of the design of a cycle track, is the quality of the finish, see 'Providing for<br />

the Cyclist'. Good surface regularity should be obtained and the materials chosen should<br />

provide a surface texture capable of obtaining a resistance to skidding in wet weather. It is<br />

also of advantage if the surface of the cycle track can be of a different colour to that of any<br />

adjacent footway. Adequate drainage must also be provided. Where a cycle track crosses a<br />

carriageway it should do so at right angles to the kerb, which should be dropped across the<br />

cycle track with an upstand not greater than 25mm.<br />

3.8.3.14 In addition to the colour of the cycle track there should be a distinctive separation between<br />

the cycle track and any adjacent footway. This may be achieved by a continuous white line<br />

marking not less than 150mm wide, or preferably by kerbs with the cycle track at a level<br />

difference of at least 50 mm to the footway. The latter method may however complicate<br />

drainage details, but is preferable as it reduces the chances of cyclists encroaching onto the<br />

footway.<br />

3.8.3.15 Cycle tracks should be provided with a reasonable standard of illumination with particular<br />

care be taken at the junction of cycle tracks with other traffic routes.
