Coordinating Traffic Signals on Two-Way Existing Roads

Presentation shows how to coordinate traffic signals on Telegraph Rd, (a two-way road, 10.4 miles in length, with 21 traffic signals) so that motorists traveling at the recommended speed make every traffic signal. Green-wave theory, the method used to achieve this result, is explained. A road-to-traveler feedback device that provides recommended speed is described.
