Abstract

This project combines a desktop study and field sampling to assess the effectiveness of traffic control devices currently in place to transition motorists from high-speed to low-speed environments. The project focuses on regional town approaches within North Queensland as there is limited research and experimentation on this sector of road safety in the area. Speed sampling, crash data and the analysis of relevant environmental factors form the basis of the evaluation of the effectiveness of traffic control devices in place.

Background information presented includes the physical and psychological elements which dictate the speed environment, speed and transition zones, current gateway treatments and other management strategies. International case study experiments relevant to transition zones approaching regional towns are evaluated and signal the performance of different treatments. The experimentation methodology employed was the speed sampling of five transition zones throughout North Queensland. Crash data within the five transition zones was critically evaluated to ascertain if a link between speed and crash data could be established.

Speed sample results indicate that the current traffic control devices are ineffective in achieving acceptable speed compliance. However, the evaluation also indicates that the crash rates in the focus areas are not significant enough to be considered high priority as current traffic control devices are effective in limiting ‘fatal crashes’. Site specific recommendations are provided for changes to improve speed compliance throughout the focus areas.
