Evaluating the performance of superstreet unconventional intersection Available to Purchase

The traffic growth and oversaturated intersections become complex challenges that need to search for solutions and innovative alternatives to reduce delay and improve the operational performance of signalized intersections. Long vehicle delays and failure cycle times or signalized crossings due to queue blockage require studying and assessing the alternative design methods. This research aims to evaluate the implementation of super street unconventional intersections to support policymakers with appropriate decisions for traffic operation improvement to mitigate traffic congestion. The conventional crossroads performed in the worst case due to traffic congestion at peak hours. The application of a super street (synchronized) intersection reduced the average delay and stopped delay by 76% and 82% for the north approach and 87% and 80 % for the south way straight. Also, the maximum queue length reduces by 57% & 88% for the north and south approaches straight; as a result, the super street intersection was superior in operational performance to a conventional crossroad and reduced the vehicle delays and maximum queue length. For short-term planning, the vehicle delay of the super street intersection is decreased for all approaches except for the south way but keeps a better performance with a level of service of (D) and (B) for north/ south and west/east straight. On the contrary, for long-term planning, the super street will operate in worse traffic conditions due to an increase in traffic demand, and the amazing street intersection will perform under oversaturated conditions with a level of service (E) for the north approach only, and that implied the practical north approach would not accommodate future traffic demand.
