Starting this summer, some traffic signals along Arapahoe Avenue will be able to recognize the Jump buses as they approach an intersection, giving them priority.

The new system will allow buses to send an electronic signal to traffic lights as they cruise along their route. When the lights receive the signal, they work to reduce the time the buses spend waiting at an intersection, either by extending an existing green light or cutting the length of a red light.

The "traffic priority system" will likely shave 5 or 6 minutes off the Jump's route, which connects Boulder to eastern Boulder County via Arapahoe, said Scott McCarey, the county's alternative transportation coordinator. But riders won't likely experience the time savings until RTD changes the route's timetable -- since buses can't run ahead of schedule -- which may not happen until next January.
