Bridj, the bus start-up that wants to use data to making commuting more efficient, will begin morning service in parts of Washington on Monday.

For its first two weeks, Bridj will operate only from 7 a.m. to 10 a.m. Its service, as anticipated, will connect Capitol Hill, Dupont Circle and the K Street corridor. Bridj uses flexible pick-up locations depending on where its riders are located on a given day. It says a rider will never have to walk more than 10 minutes inside one of its service zones.

The Boston-based start-up recently began e-mailing details to District residents who have expressed an interest in the service. For now, it’s including promo codes for free rides during the launch period.

After the trial period, Bridj is expected to cost $5 a ride and will eventually expand to other neighborhoods. All payments are processed through its app. As it considers future routes, the start-up is taking into consideration commutes submitted by users who visit its Web site.
