Past research shows that access connections and signalized intersections within the functional area of an interchange can adversely impact safety and operations at the interchange and on the freeway. A variety of transportation problems occur when driveways and intersections are too close to interchange ramps. Signalized intersections too close to ramp termini can cause heavy volumes of weaving traffic, complex traffic signal operations, accidents,congestion, and traffic backing up the ramps on to the main line. |
