In a continuing effort to address parking and traffic difficulties well-known to Bostonians, along with making the city a bit more green, the Walsh administration is bringing 80 new car-share vehicles to the streets.

The cars, which are part of the DriveBoston program, will be parked in allotted city-managed spaces, Mayor Martin Walsh’s office said in an Aug. 26 statement. Ten of these spots will be in Dorchester, 12 in Roxbury, eight in Jamaica Plain, and the rest scattered throughout the city.  The first location is set for Dudley Square, with others expected to be rolled out through the fall.

Most of the cars are intended to service areas with few car-share options, with a particular focus on beefing up presences at “key MBTA stations” and bus routes.

In a statement, Walsh said: “All of our residents deserve the opportunity to access car-share vehicles and I am pleased we are able to expand DriveBoston to additional neighborhoods.”

The mayor said the program is a tool to not only relieve congestion throughout the city, but reduce reliance on car ownership as a means of transportation.

ZipCar and Enterprise Carshare — which work by registering with the company and reserving cars for specific amounts of time — are the program partners, the mayor’s office said. Designating the parking spots will involve the Boston Transportation Department (BTD) expanding existing lots, the statement said, beginning this week. Of the 80 spots, 48 will be located in city-owned parking lots and the remaining 32 on street corners.

DriveBoston is an early step in Go Boston 2030, the city’s transportation initiative. Over the next 15 years, Go Boston 2030 aims to improve equality of transportation, reduce environmental impact, and catalyze economic growth, according to its website.

“We are excited to continually offer new ways for people to get around the city,” said Gina Fiandaca, BTD commissioner. “Not everybody wants to own a car, but they may need one occasionally, and we see DriveBoston as one more tool for residents who want a car-free or car-light way of living in Boston.”

The increase in designated car-share, and therefore publically unusable, spots is expected to be offset by the fewer residents needing to buy and maintain cars, the Walsh administration said. Findings from a 2010 North American shared-use transportation study cited in the report estimated that each car sharing vehicle introduced removed anywhere from nine to 13 cars from the road.

The city plans to analyze car use data to improve and fine-tune BostonDrive as it moves along,  according to the statement. The data is expected to help evaluate the program’s success further down the line.
