Hindmarsh Drive Traffic Signals
This document summarizes a feasibility study of improving three intersections along Hindmarsh Drive in Canberra: Eggleston Crescent, Launceston Street, and the Tuggeranong Parkway southbound off-ramp. The study analyzed traffic volume, speed, and crash data to identify options for improving safety and access. Options considered included closing/reopening streets, adding turn lanes, roundabouts, and traffic signals. The recommended and draft designs proposed traffic signals at each intersection to improve traffic flow and safety along the busy arterial route while minimizing impacts to residents and congestion. Subject to funding, construction was anticipated to begin in late 2016.

- 5. Feasibility Study Included: • TrafficSurveys (speed / volume) • Review road hierarchy • Analyse crash history • Review existing intersections • Create a traffic model • Identify options / solutions
- 6. Options Analysis Eggleston /Launceston • Close Eggleston Crescent / Reopen McDonald Street • Impacts on local residents in MacDonald Street • Delays on Hindmarsh Drive (4-way signals) • Additional works on adjacent road network (i.e. MacDonald Street / Eggleston Crescent) • Provide accelerations lanes • Safety concerns when merging at high speed • Insufficient distance to cross three lanes
- 7. Options Analysis Eggleston /Launceston • Roundabouts • Do not work with dominant traffic flows • Not enough space • Reducing Hindmarsh Drive to two lanes • Large reduction in traffic flow on arterial route • Increased congestion / journey time • Increased congestion = decreased safety • Traffic Signals (using existing intersection layouts) • Considered feasible
