A modeling effort was used to investigate the potential impacts of coordinating traffic signal control between several jurisdictions along congested arterial corridors leading into Seattle.

FINDINGS

The model projected an increase in average vehicle speeds that would help reduce the number of expected crashes on the corridor by 2.5 percent and contribute to a 1.1 percent reduction in the number of expected fatal crashes over a ten-year period.

The Seattle metropolitan area had a considerably high level of ITS implementation prior to the MMDI projects, therefore the experiences of localities implementing these systems under differing conditions may vary significantly from those reported in Seattle.
