Greenways Cycle Corridor Road Safety Audit
Tonkin Consulting undertook a road safety audit along Marion and Daws Road Park Holme assessing two concept alignments for a shared path on the Adelaide to Marino Rocks Greenway Cycle Corridor.
The corridor runs roughly parallel to the rail line between Railway Terrace to the north-east and Minchinbury Terrace to the south-west. The two alignments crossed Marion Road and Daws Road, and therefore pedestrian and cycling safety needed to be considered in the design, which the audit focussed on.
The report presented general findings on project considerations, as well as site-specific design issues and their relationship to the various road users. The issues identified and associated recommendations were provided for further consideration and investigation by the design team.
As the audit was undertaken early in the overall planning and design process, Tonkin Consulting also provided strategic comment for enhanced features for the walking and cycling route.
Both concepts were reviewed and assessed as follows.
- Shared path running on the northern side of the railway line between Railway Terrace and Minchinbury Terrace, incorporating a new section of path between Daws Road and Marion Road. Explored options included: incorporating pedestrian actuated crossings of Daws and Marion Roads; and incorporating unsignalised crossings of Daws and Marion Roads (i.e. pedestrian/cyclist refuges)
- Shared path crosses the rail line beneath the railway bridges at Daws and Marion Road, with the route running on the southern side of the rail line between these roads, along Brenda Street. This concept incorporates the existing refuge location where crossings are nominally unsignalised.
- Preliminary design audit of the preliminary design plans in accordance with Austroads Guidelines.
- Site review during daylight, then subsequently evening hours to assess existing conditions.
- Review crash data and pedestrian and cyclist survey.
- Analyse existing pedestrian and cyclist crossing facilities, examining issues related to designs and relate to findings from the site assessments.
- Provide a full report of findings and recommendations.
