This Issue's Perspective
As a crucial hub connecting the ancient city's interior and exterior, and bridging the east and west, north and south.Jingzhou's Dongmen Road intersection experiences traffic congestion during peak hours as a norm. In this issue, we will...Optimize
Hubei · Dongmen, Jingzhou City
Intersection Overview
East Gate is the entrance and exit to the ancient city of Jingzhou.Significant Channel，Ongoing operation in a state of hyper-saturationThis node connects Jiangjin Road (an east-west corridor in the central urban area) with Donghuan Road (a vital passage linking the old city, Jingbei New Town, the high-speed railway station area, and the复兴 Avenue). It is in urgent need of systematic renovation to enhance overall traffic efficiency.Morning and evening rush hours experience a certain tidal phenomenon.
Issue Analysis
City gatePeak Season CongestionOverflow to the upstream intersection, causing congestion; the pressure on entering and exiting the city is significant. (The reason is that the city gate is narrow, a natural bottleneck for traffic; the road section from the city gate to the East Gate intersection is short, the dispersion at the city gate is slow, and the expansion section of the westbound entrance at the East Gate intersection is short, with insufficient vehicle storage capacity.)
2. Left turns prohibited at all times, butHigh demand for left-hand turn at West Entrance during off-peak periods；
Turn right to enter or exit the ancient city.Significant conflicts between motor vehicles, pedestrians, and non-motorized vehicles.
4. Morning rush hourSouthbound and left-hand turns are both congested.The saturation is nearly 1.0, with a queue length of 300 meters to the roundabout position.Severe congestion on the northbound entrance during the evening rush hourOverflowing to Jingming Guan Road, the queue often extends to Zhiding First Lane, with a length exceeding 650 meters.
Congestion Duration: 7:45-8:20; 5:30-6:20 p.m.
Optimized Approach
1. Enhancing traffic throughput, refining the Jiangjin Road-Dongmen IntersectionTiming Solution，Monday to Friday and weekend scenarios, with 11 detailed time-slot plans.Peak morning commute period of 90 seconds, and coordination established with upstream and downstream intersections.
2. SetupVariable Lane，Peak Season Left Turn BanEnhancing traffic flow efficiency, allowing left turns during off-peak hours to accommodate diverse traffic demands across different time periods, offering a more flexible approach to road usage.
3. Dongmen Cave Entrance PeakNon-motorized vehicle detourEnhanced evacuation measures to prevent overflow are in place; non-motorized vehicles are detoured around BinYang Building and neighborhood streets, a distance of 330 meters.
4. Right IslandIncrease Lighting ControlsMeasure input by output, Eastern Gate, EasternGreen Wave Coordination Plans are established in all four directions: north, south, east, and west.
Effect Comparison
JingzhouThe traffic optimization at Dongmen Intersection has successfully alleviated congestion through precise problem analysis, scientific strategy formulation, and effective implementation of measures, enhancing the citizens' travel experience. Looking ahead, we will continue to monitor urban traffic dynamics, constantly refine traffic management plans, and strive to create a more open and convenient travel environment for the public.
Jingzhou East Gate, also known as "Yinbin Gate," is a significant gateway and transportation hub of the ancient Jingzhou City.The moat outside the Eastern Gate and the ancient city wall blend harmoniously, creating a unique charm of the old city.Today, the Dongmen area has become a crucial traffic hub: Donghuan Road extends northward from here, connecting the new northern area with the high-speed rail station area; Jiangjin Road runs east to west, linking the city's core regions. It serves as both the starting point for tourists to explore the ancient city's history and a vital route for locals' daily commutes. The fusion of classical charm and modern functionality here testifies to the inheritance and development of Jingzhou, this historic and cultural city.
