Tonkin Consulting undertook a road safety audit investigating the preliminary Main South Road design from Seaford Road to the Victor Harbor Road.
The audit examined road conditions with a specific focus on road safety implications for all anticipated road users. The objective (as with any road safety audit) was to provide a subjective review of the current operating conditions at site, as they relate to road safety, and identify any issues and factors that might contribute to the potential or severity of vehicle collisions.
The section of road examined marked in the preliminary plans, is approximately 1200 m in length on a longitudinal incline from north to south. It included two major junctions, one at Patapinda/Seaford Roads (existing signalised control), and the second at Victor Harbor Road (signals proposed). A number of other direct accesses to commercial and residential properties and minor road junctions were also analysed.
The speed limit on this section of South Road is 60 km/h with 80 km/h zones on both approaches. The area has a significant amount of commercial activity, several bus stops and properties with direct access to South Road, each providing their own mix of issues.
This investigation and subsequent report presented the general findings on the project considerations, as well as site specific design issues and their relationship to the various road users.
