Abstract: To explore the relationship between on-road parking and dynamic traffic, the analytic hierarchy process is employed to quantitatively assess the influencing factors concerning on-road parking and dynamic traffic. The synthetic weights of each coupling index are calculated using MATLAB software. According to the synthetic weights, parking frequency, average parking time and road traffic volume are selected as the coupling indexes. A coupling relationship model between on-road parking and dynamic traffic is developed, and the corresponding parking scheme is proposed. By analyzing in-road parking and dynamic traffic flow on Zishi roads, the existence of a coupling relationship is exemplified and validated. The results show that the implementation of parking scheme can increase the speed of dynamic traffic flow by 11.1% on average, effectively mitigating the negative impact of on-road parking on dynamic traffic flow, and improving the efficiency of road operation.
