Investigation and Research on the Traffic Situation of Yiyang Zijiang No.3 Bridge 1998 was completed and officially opened to traffic on June 28th, 2002. It is located between Zijiang No.1 Bridge and No.2 Bridge, 2800 meters away from Zijiang No.1 Bridge in the west and 1050 meters away from Zijiang No.2 Bridge in the east. There are 4 auxiliary holes, each with a span of 60 meters, and it is a through box ribbed arch bridge; The main bridge has three main holes with spans of 102, 1 14 and 102 m, respectively, and is a half-through concrete-filled steel tubular arch bridge. The maximum span of the main bridge is 1 14m. It was the longest span steel tube arch bridge in our province at that time. The bridge is 24.5 meters wide, including 20 meters of roadway and 2×2.25 meters of sidewalk. The width of the steel tube arch bridge is 27. 1 m, and the seismic grade is 7 degrees. It has been used for seven years. With the rapid development of urban traffic and the increasing number of motor vehicles in the central city, urban bridges have occupied a decisive position in urban transportation hubs. As the Second Zijiang Bridge in Yiyang City is a special bridge for Chang-Chang Expressway built by the transportation department, Chang-Chang Expressway will be completely closed after it is opened to traffic, losing its function as a city bridge. If we only rely on Zijiang No.1 Bridge to solve the communication between the south bridge and the north bridge and the smooth flow of 3 19 national highway, it is certain. Therefore, the completion and opening to traffic of Zijiang No.3 Bridge has played a positive role in easing the traffic flow of Zijiang No.1 Bridge and speeding up the traffic speed on the north and south sides. The bridge is located on the East Ring Road in the central city of Yiyang. The south of the bridge crosses Sanliqiao Square and is connected with the East Ring Road and Longzhou Road respectively. The north of the bridge is connected with Wuyi Road through Wuyi overpass, which is not only the traffic bridge of National Highway 3 19, but also the urban bridge connecting the north and south parts of Zijiang River in Yiyang central city, which greatly relieves the traffic pressure of the first bridge of Zijiang River and is closely connected with the road network of the central city through wiring engineering. Second, the traffic safety status of Yiyang Zijiang Third Bridge Since the opening of Yiyang Zijiang Third Bridge, there have been thousands of cars on average every day. In order to effectively alleviate the traffic flow of Zijiang No.1 Bridge, the government expressly stipulates that large vans, low-speed trucks and three-wheeled trucks are prohibited from passing through Zijiang No.1 Bridge. On June 28th, 2008, the toll station of Zijiang Third Bridge was collapsed by heavy snow. In order to further optimize the economic and investment environment, the Municipal Party Committee and the Municipal Government made an important decision in June this year: the toll station of Zijiang No.3 Bridge was abolished, and most foreign transit vehicles and urban vehicles were changed from Zijiang No.1 Bridge to Zijiang No.3 Bridge, and the traffic volume of Zijiang No.3 Bridge was also increasing day by day. With the continuous increase of traffic flow and people flow, traffic safety hazards are increasingly prominent. According to preliminary statistics, dozens of traffic accidents have occurred on Ziyang Third Bridge this year alone, including two major traffic accidents and one major hit-and-run accident. 1, the bridge itself has traffic safety hazards. Last year, the municipal public bureau, the department in charge of the maintenance of the Third Zijiang Bridge, inspected the bridge and found many potential safety hazards. Because the bridge deck is paved with modified asphalt concrete, after years of rolling by large and small vehicles, many cracks of different sizes appear on the surface, with obvious loose segregation. The expansion joint of 1 1 was also damaged by long-term rolling of vehicles. After discussing with relevant experts and reporting to the government for approval, the Municipal Public Utilities Bureau carried out an overhaul of the Zijiang Third Bridge, but these safety hazards may still exist in the future driving process. In addition, the supporting facilities are not perfect, and the brightness of the street lamps on the bridge deck is not enough, which directly affects the driver's sight at night, thus causing traffic accidents. 2, the driver's own traffic safety awareness is not high. Before the toll station of Zijiang Third Bridge was demolished, drivers would naturally slow down when driving through the Third Bridge, because there was a toll station ahead. At present, the toll station of Zijiang Third Bridge has been demolished, and the deck of Zijiang Third Bridge is made of modified asphalt concrete, which is relatively flat. Drivers often drive at high speed when driving through bridge three, especially at night. For example, on July 15 this year, a "Fukang" car was driving from south to north along the third Zijiang Bridge. Because its speed was too fast, it collided with an electric bicycle on the bridge deck of the North Approach Bridge of the Third Bridge, causing the driver of the electric bicycle to die on the spot. Iii. Suggestions on the treatment of traffic safety hazards of Zijiang Third Bridge 1. Strengthen departmental cooperation. The traffic management department of public security should actively maintain good communication and close contact with relevant departments such as the construction, maintenance and repair of the Third Bridge, and timely put forward suggestions and measures for the rectification of traffic safety hazards of the Zijiang Third Bridge, so that relevant departments can maintain and repair the bridge body in a targeted manner, such as increasing the brightness of street lamps on the bridge deck, repairing damaged roads and guardrails, etc., and eliminate safety hazards from the source as soon as possible. 2. Improve traffic facilities. It is suggested that the traffic police department further improve and update the traffic facilities of Zijiang Third Bridge, change the double yellow lines of Zijiang Third Bridge into safety guardrails, and set traffic guardrails at both ends of the bridge, especially at the junction of Wuyi Overpass and Zijiang Third Bridge, and set eye-catching traffic signs and speed limit signs at the north-south entrance of the bridge to prevent traffic accidents caused by speeding and unfamiliar drivers from other places. 3. Strengthen the traffic safety control of Zijiang Third Bridge. As a traffic police department, we should further strengthen the control of Zijiang Third Bridge. It is suggested that monitoring systems should be set up at both ends of Zijiang Third Bridge to monitor passing vehicles around the clock, so as to facilitate the identification of traffic accident responsibility and the detection of traffic accident and escape cases and criminal cases in the future, and to prevent the occurrence of traffic accident and escape cases to a certain extent. At the same time, strengthen bridge deck patrol, find problems in time, and eliminate traffic safety hazards.
