Innovative interchange designs are gaining attention due to their potential in reducing delays and mitigating congestion. This study was aimed at proposing the super diverging diamond interchange (SDDI) as an alternative design to the conventional diamond interchange (CDI), diverging diamond interchange (DDI), diverging partial cloverleaf interchange (DPCI), folded diamond interchange (FDI) and ramp crossover interchange (RCI) designs. An evaluation of the operational performances of the six interchange designs in terms of both vehicular and pedestrian travel times was conducted. The VISSIM micro-simulation software tool was used where several scenarios were proposed and examined. The study was carried out for the E. Mississippi Ave. and I-225 interchange in Aurora, Colorado as part of a project. Note that the interchange, mentioned, is currently operating as a CDI. ANOVA hypothesis tests were conducted to compare the travel times required for both vehicles and pedestrians to navigate each interchange type. The results indicated that, for under-saturated conditions where demand volumes were less than the interchanges’ capacities, implementing either the FDI, SDDI or RCI designs substantially reduced vehicular travel times as opposed to implementing the other designs. On the other hand, for over-saturated conditions in which traffic volumes exceeded capacities, the RCI and FDI exhibited the least vehicular travel times. The CDI was demonstrated to be the most efficient interchange serving pedestrians in all simulated scenarios. It was closely followed by the RCI and SDDI particularly for over-saturated conditions.

将超级分散钻石互换与其他创新互换的效率进行比较

创新的互换设计因其减少延迟和缓解拥堵的潜力而备受关注。这项研究的目的是提出超级散布钻石互换(SDDI)作为常规钻石互换(CDI),散布钻石互换(DDI),散布部分苜蓿叶形互换(DPCI),折叠钻石互换(FDI)和坡道的替代设计交叉交换(RCI)设计。从车辆和行人的出行时间两个方面对六个互换设计的运行性能进行了评估。在提出和检查了几种方案的情况下,使用了VISSIM微型仿真软件工具。该研究是在科罗拉多州奥罗拉市的密西西比大道E.和I-225交汇处进行的,这是该项目的一部分。请注意,提到的互换,当前作为CDI运行。进行了方差分析假设检验,以比较车辆和行人通行每种交换类型所需的行驶时间。结果表明,对于需求量小于交汇处通行能力的欠饱和条件,实施FDI,SDDI或RCI设计与实施其他设计相比,大大减少了车辆的行驶时间。另一方面,对于交通量超出容量的过饱和条件,RCI和FDI的车辆行驶时间最少。在所有模拟场景中,CDI被证明是为行人提供服务的最高效的立交桥。RCI和SDDI紧随其后,特别是在过饱和条件下。进行了方差分析假设检验,以比较车辆和行人通行每种交换类型所需的行驶时间。结果表明,对于需求量小于交汇处通行能力的欠饱和条件,实施FDI,SDDI或RCI设计与实施其他设计相比,大大减少了车辆的行驶时间。另一方面,对于交通量超过容量的过饱和条件,RCI和FDI的车辆行驶时间最少。在所有模拟场景中,CDI被证明是为行人提供服务的最高效的立交桥。RCI和SDDI紧随其后,特别是在过饱和条件下。进行了方差分析假设检验,以比较车辆和行人通行每种交换类型所需的行驶时间。结果表明,对于需求量小于交汇处通行能力的欠饱和条件,实施FDI,SDDI或RCI设计与实施其他设计相比,大大减少了车辆的行驶时间。另一方面,对于交通量超出容量的过饱和条件,RCI和FDI的车辆行驶时间最少。在所有模拟场景中,CDI被证明是为行人提供服务的最高效的立交桥。RCI和SDDI紧随其后,特别是在过饱和条件下。结果表明,在需求量小于交汇处通行能力不足的饱和条件下,与实施其他设计相比,实施FDI,SDDI或RCI设计大大减少了车辆行驶时间。另一方面,对于交通量超出容量的过饱和条件,RCI和FDI的车辆行驶时间最少。在所有模拟场景中,CDI被证明是为行人提供服务的最高效的立交桥。RCI和SDDI紧随其后,特别是在过饱和条件下。结果表明,对于需求量小于交汇处通行能力的欠饱和条件,实施FDI,SDDI或RCI设计与实施其他设计相比,大大减少了车辆的行驶时间。另一方面,对于交通量超出容量的过饱和条件,RCI和FDI的车辆行驶时间最少。在所有模拟场景中,CDI被证明是为行人提供服务的最高效的立交桥。RCI和SDDI紧随其后,特别是在过饱和条件下。与实施其他设计相比,SDDI或RCI设计大大减少了车辆的行驶时间。另一方面,对于交通量超出容量的过饱和条件,RCI和FDI的车辆行驶时间最少。在所有模拟场景中,CDI被证明是为行人提供服务的最高效的立交桥。RCI和SDDI紧随其后,特别是在过饱和条件下。与实施其他设计相比,SDDI或RCI设计大大减少了车辆的行驶时间。另一方面,对于交通量超出容量的过饱和条件,RCI和FDI的车辆行驶时间最少。在所有模拟场景中,CDI被证明是为行人提供服务的最高效的立交桥。RCI和SDDI紧随其后,特别是在过饱和条件下。
