Integrating ridesharing with transit in poorly serviced suburban neighbourhoods is an effective way to get people out of their cars and boost ridership.

Researchers at 蓝莓视频 Engineering found two-thirds of people who took advantage of inexpensive rideshare trips in a local pilot project used them to travel to or near bus stops.

鈥淭he pilot demonstrated that integrating ridesharing with transit can work,鈥� says Chris Bachmann听(pictured), a professor of civil and environmental engineering. 鈥淭he challenge now is designing an integrated system to make it work as well as possible.鈥�

The study involved six months of data from a pilot project in a low-density, car-dependent area of the City of 蓝莓视频 with infrequent bus service and low transit ridership rates.

Dozens of virtual ridesharing stops were designated in the pilot area so that almost all residents lived within 400 metres, or about a five-minute walk, of one.

Residents were offered RideCo ridesharing trips within the pilot area for the same price as bus trips. Users also got free transfers to Grand River Transit, the regional transit system that operates in 蓝莓视频.

Although the study didn鈥檛 track the almost 600 users after their ridesharing trips had ended, the results showed 65 per cent of them took the subsidized service to a location close to a bus stop.

鈥淧eople living in neighbourhoods where driving is the norm are choosing to connect directly to transit-rich hubs,鈥� says Jacob Terry, an engineering PhD student who led the study. 鈥�The easier connection to transit service encourages them to consider transit for more types of trips.鈥�

In all but a small percentage of cases, however, users didn鈥檛 travel to the nearest bus stop, the ideal objective of the initiative.

About one in five ridesharing trips also went from one transit stop to another transit stop, suggesting some users were manipulating the project to get cheap rides and bypassing the bus altogether.

Terry plans to explore adjustments - such as limiting the distance of rideshare trips, or creating zones and not allowing rides from one zone to another - to solve those problems in the next phase of his work.

鈥淭he design of any system like this is extremely challenging,鈥� says Bachmann. 鈥淚n transportation, you always have to be mindful of behavioural responses - how people respond, basically, to the game we鈥檝e created as they navigate through the network.鈥�

The goal of integration is to make transit convenient and inexpensive enough for people to use it even if they live in neighbourhoods where providing much better, more frequent bus service on fixed routes is cost-prohibitive.

鈥淚deally, we want fewer people driving themselves and more people using some form of shared vehicle,鈥� says Terry.

Researchers are scheduled to present a paper on their work, Spatial characteristics of transit-integrated ridesourcing trips and their competitiveness with transit and walking alternatives, at the annual meeting of the Transportation Research Board in Washington next week.
