Chapter 28 - Standard Requirements c) Recommended pavement structure is based on the subgrade having a minimum strength of soaked CBR of 7. Subgrade improvement may be necessary to achieve this strength; d) Where adequate test informati on is available, the Council may accept other designs for the road structure when supported by adequate engineering justification; e) Where adequate provision is made for separate pedestrian traffic, and passing and road parking, lesser carriageway width may be acceptable; f) Where carriageway width of two lanes only is provided, careful design of parking is required. (Refer Code of Practice for Subdivision and Land Development); g) Acceptable guides to road design are: State Highway Pavement Design and Rehabilitation Manual 1989 (SHPDRM); and Rural Road Design - Guide to the Geometric Design of Rural Roads - Austroads 1989; and h) ‘Recommended carriageway width’ is the sealed width of traffic lanes. A seal widening of at least 0.3 metres on each side is generally desirable. 28.1.14.2 Provision for Pedestrians and Non-Motorised Road Users 28.1.14.2.1 The design of subdivisions and developments should incorporate pedestrian access routes connecting residential areas, schools, shopping centres, recreation reserves, and public transport collection points and terminals. 28.1.14.2.2 Bicycle traffic should be provided for within road carriageways and should ensure adequate and safe lane width and riding surfaces to incorporate both bicycles and vehicles. Separate bicycle tracks, not forming part of a road carriageway, may be provided where, for reasons of shorter distance or safety, it is unreasonable to incorporate bicycle traffic on the road carriageway. In general, bicycle traffic will be included within the road carriageway. 28.1.14.2.3 Pedestrian footpaths should be provided separate from the road carriageway. Public footpaths should be constructed to have permanent concrete or asphaltic surfaces and should be designed to minimise any surfacewater flow across the footpath which would be an impediment or hazard to pedestrians. 28.1.14.2.4 It is preferred that the longitudinal profile of footpaths should not be depressed by vehicular crossings. 28.1.14.2.5 Pram and wheelchair crossings shall be provided in pedestrian footpaths at road intersections. 28.1.14.2.6 Footpath gradients should not exceed 1 in 6 and where this gradient is exceeded, steps or other safety measures may be required. 28.1.14.2.7 Where footpaths or accessways are intended to be used by both cyclists and pedestrians some form of separation of the two users should, for safety reasons, be provided. 28.1.14.2.8 All pedestrian accessways should be bounded by a fence. 28 - 11
