STRATEGIES FOR INCREASING THE EFFECTIVENESS OF CROSS SECTION CHANGES AT SIGNALIZED INTERSECTIONS

Research was conducted to develop design guidelines for maximizing capacity for three intersection configurations with auxiliary lanes. A survey of practices of state agencies showed that no states presently design any of these intersection configurations with capacity maximization as a design objective. A literature review revealed very little applicable background material, and those procedures which do exist treat upstream and downstream sections independently. Since the effectiveness of an auxiliary lane depends on the amount of traffic using it, data were collected so that those factors which significantly affect lane utilization could be identified. Mathematical models describing this utilization were then developed. These lane utilization models were adjusted so that auxiliary lane length could be obtained for specified auxiliary lane utilization. Spreadsheet software was developed for each of the three intersection configurations whereby auxiliary lane lengths could be designed.
