Abstract

Existing unconventional intersection designs can enhance the capacity of intersections to deal with repaid pressure on urban commuting, whereas they force vehicles to multi-stop and reorganize, resulting in safety risks and high fuel consumption. This paper proposes the Intermittent Lane Intersection (ILI) that combines the advantages of variable lane intersection and CTE (Combining the tandem control and exit lanes for left-turn control). An integrated optimization model is established to obtain the optimal geometric and signal control parameters, and a homothermic genetic algorithm is used to solve the model. Then, the application of ILI in different traffic demands of the Tianfu Third Street intersection is analyzed. Compared with the benchmark design (TI, CTE, and CTE with signal coordinated control), ILI can effectively reduce intersection delay, fuel consumption, and parking times. Additionally, ILI has great application superiority when the traffic arrival rate is [1500,1700] and the left-turn ratio is [0.40,0.60].

间歇车道交叉口设计和动态信号控制的综合优化：效率、安全和油耗

现有的非常规交叉口设计可以提高交叉口的通行能力，以应对城市通勤的补给压力，但却迫使车辆多次停车和重组，造成安全隐患和高油耗。本文提出的间歇车道交叉口（ILI）结合了可变车道交叉口和 CTE（结合串联控制和出口车道进行左转控制）的优点。建立了一个综合优化模型，以获得最佳几何和信号控制参数，并使用同温遗传算法对模型进行求解。然后，分析了 ILI 在天府三街交叉口不同交通需求下的应用。与基准设计（TI、CTE 和带信号协调控制的 CTE）相比，ILI 可有效减少交叉口延误、油耗和停车时间。此外，当交通到达率为[1500,1700]，左转率为[0.40,0.60]时，ILI 具有很大的应用优势。
