case study

Origin-Destination data for Rat Running

A north Sydney council wanted to know if people were cutting through small streets instead of using the main road to get from one place to another.

If it was found that people were using residential streets to avoid the main road, then the council wanted to reduce the instances of these rat runs.

Rat running is problematic because local roads cannot handle larger volumes, which can disrupt local communities and residents.

Where vehicles are theorised to travel.

The council used connected vehicle data answer the following questions: are vehicles using one or more shortcuts? Which shortcut is being used the most? Are there any other shortcuts in the area? What is the time difference between using the main road vs the local roads? and what percentage of drivers are using the shortcuts compared to the main road? The council also compared average travel time for the various paths taken, average speed for said paths, times of day (e.g. peaks and off peaks, school peaks, etc.), and percentage of vehicles using the rat running route

Where cars travel during evening peak hours on the main road.
Where vehicles travel during non-peak hours near Early St.
Where vehicles travel the most.

The council established that 48.9% of driers were using shortcuts in the morning peak across different local roads and that more drivers used the local roads on weekdays compared to weekends. By enabling the council to gain insight into how drivers behave on these roads at certain times, there can be a clearer idea of how and where to prevent these rat runs.
