SEGMENTWIDE TRAFFIC RESPONSIVE FREEWAY ENTRY CONTROL: FREEWAY CORRIDOR MODELINE, CONTROL STRATEGY, AND IMPLEMENTATION PLAN

Major outcomes of this research are threefold: development of a macroscopic freeway corridor simulation model (FRECON2); development and evaluation, by simulation, of a segmentwide traffic responsive freeway entry control strategy (ELT control); and development of field implementation guidelines. The macroscopic freeway corridor model, FRECON2, was developed by extending an existing macroscopic dynamic freeway model, FRECON, in the following three areas: priority entry treatment, drivers' spatial diversion, and alternative surface streets with flow-dependent travel costs. Then, FRECON2 was calibrated using two days' data from the Santa Monica Freeway Corridor in Los Angeles, California. As a new segmentwide control strategy, extended local traffic responsive (ELT) control was developed. ELT control has been applied, by simulation, to freeway corridors with different operating environments. When its performance was evaluated, ELT control achieved a three to eleven percent net savings in total corridor travel time. Based on the above results, guidelines for field implementation have been prepared, including development of software for the central computer and 170 type controllers, and a before and after study plan.
