The research was to study the total effect of off-ramps on freeway operations. This effect was related to the following factors: (1) deceleration distance used by exiting vehicles; (2) off-ramp capacity calculated from simulation of the off-ramp junction with a parallel one-way frontage road; (3) short trip generation on the freeway as related to ramp spacing; (4) weaving maneuvers by exiting vehicles; (5) access control; and (6) access provision. To some extent the research delineates the effect of off-ramp location on arterial street and frontage road operation. The relative merits of diamond, x-type interchanges and stacked ramps are considered. Stacked ramps are considered economically infeasibility except where the highest level of service is mandatory.
