A Signal Coordination Control Based on Traversing Empty between Mid‐Block Street Crossing and Intersection

Abstract

To solve the problem in pedestrian Mid-Block street crossing, the method of signal coordination control between mid-block street crossing and intersection is researched in this paper. The paper proposes to use “distance-flow rate-time” graph as the tool for building coordination control system model which is for different situations of traffic control. Through alternating the linear optimization model, the system outputs the distribution of signal timing and system operational factors (delays in vehicles and mid-block street crossing). Finally, taking one section on the Taiping North Road in Nanjing as an example, the signal coordination control is carried out. And the results which are delays in the vehicles and mid-block street crossing are compared to those in the current distribution of signal timing.

Coordinated Traffic Signal Design for Major Intersections in Sylhet City

“…Considering a common cycle length for coordinated signals is essential. In principle, the longest cycle length among the coordinated intersections is considered as group cycle length [12]. Either Webster's equation or the Greenshields-Poisson Method can be used to determine the cycle length and splits.…”

“…Justification or check for green time extension of coordinated phase is the next portion of this calculation, where it is checked whether the green extension is needed or not for clearance of vehicles from both coordinated and noncoordinated phases of adjacent intersection [12]. The time needed for clearance of vehicles from the coordinated phase of the previous intersection was calculated by multiplying the percentage of through-moving vehicles with the green time of that phase.…”

“…If signals at intersections are 800 meters apart along a road then these signals should be coordinated [1]. Several studies in the literature have been found to focus on coordinated signal design [8][9][10][11][12]. However, no studies have been found to explore the scope of traffic signal coordination for intersections in Sylhet city.…”

Integrated optimization of location and signal timings for midblock pedestrian crosswalk

“…The locations of Intersections 1 and 3 are set at 0 and L , and the added midblock crosswalk (Intersection 2) location is denoted by x ( L 1 ≤ x ≤ L 2 ). The location and signal settings of the crosswalk are to be optimized to minimize its negative impact on vehicles, which is measured by the maximum bandwidths available . There is no doubt that wider greenbands lead to a lower impact.…”

The Bus Station Spacing Optimization Based on Game Theory

“…In order to make the two combined, that is, to minimize the cost, passenger bus travel will introduce two-person Nash bargaining problems. So define the following parameters [16]:…”
