Identifying Pinch Points on the road network

The client wanted to understand if the width of the Heathcote Road Bridge over the Woronora River was causing drivers to brake suddenly and violently due to the narrowness of the lanes. A study was done to analyse how motorists interacted with that specific section of road.

Using connected vehicle data, the client analysed G-forces, braking and accelerating to identify driver behaviour to confirm the hypothesis that the lanes were too narrow and justify widening the bridge.

The results found that vehicles approaching the bridge would slow down and then speed up as they exited. Along with those actions, empirical data showed that the vehicles were braking at a sudden enough level that indicated abnormal actions and justify widening the bridge to prevent further congestion.
