Study shows one-way carsharing cuts traffic

By News Editor / Updated: 27 Jul 2016

Flexible one-way carsharing models can complement existing mass transport options, reduce the number of vehicles on the road and improve mobility in densely populated urban areas, a new US study says.

The University of California Berkeley’s Transportation Sustainability Research Center (TSRC) studied the effect of one-way carsharing service car2go on a number of North American cities.

This study gathered data from nearly 9 500 North American car2go members in Calgary, San Diego, Seattle, Vancouver, and Washington, D.C, and analysed car2go activity data from those cities.

Across the five cities studied, researchers found that car2go members sold between 1 to 3 vehicles for every car2go vehicle.

Some 74 per cent of the vehicles reported sold by car2go members were at least 10 years old, helping to remove thousands of vehicles with outdated emission systems from urban roads.

The average age of vehicles reported sold was 14.4 years old.

‘Vehicle ownership in cities can be expensive and inconvenient, with private vehicles sitting unused approximately 95% of the time,’ said Susan Shaheen, co-director for UC Berkeley’s TSRC.

'Our three-year research effort into one-way carsharing in North America revealed that car2go is having a beneficial impact on mileage driven, greenhouse gas emissions, and the total number of vehicles in the cities we studied.'
