This project considers coordination between expressway and arterial systems. Plans for a Pilot Project would involve a tie–in of Eisenhower Expressway to Chicago DOT signals by having ramp queue detectors, both for on–ramps and off–ramps. Ramp terminal signal control would then be modified to either hold entry to I–290 (on–ramp congestion) or clear the off–ramp (spillback onto I–290). The implementation might link CDOT signals with IDOT Traffic Systems Center, or whether have local links to ramp meters only. This project is in progress.
