Background of Dazhou Rail Transit Construction

"If you don't see me, Wen Jialiang walks online and walks sadly; If you don't pay attention, the traffic at Tongchuan Qiaotou will be difficult to flow smoothly ... "In Dazhou, whether it is from the urban area to the south or from the urban area to the north, traffic jams may make you" stranded "on the road at any time, so it is urgent to improve urban traffic. Dazhou has approved the traffic improvement plan for the central city. While adding footbridges and building ring roads, the elevated roads along the Zhouhe River will also be designed and planned. Moreover, the preliminary work and planning and design of rail transit will also be put on the agenda, and construction will start during the 13 th Five-Year Plan period. On the afternoon of 2014165438+10/7, Mr. Luo took a taxi to Beiwai North Bus Station in the west of Dazhou City. The driver began to discuss with Mr. Luo before it was delivered to the designated place. "Can you take two more steps? If you go any further, it will be blocked. " The taxi driver began to put in a good word for Mr. Luo because there was a traffic jam outside Beiwai North Bus Station.

In Dazhou, such blocking points can be found in Wenjialiang, which leads to the west in the city center, and Tongchuan Bridge, which leads to the south. It can be said that "one car is off, but ten thousand cars can't drive".

"There are historical reasons and practical factors for traffic congestion in the central city." Yesterday, Huaxi Dushi Bao reporter learned from Dazhou transportation department that it is increasingly difficult to meet the rapidly growing demand for motor vehicles due to the current situation of urban roads and infrastructure problems.

It is understood that from 2008 to 20 13, the number of motor vehicles in Dazhou increased by 34% annually, from 32,000 to140,000. While the number of motor vehicles has increased abnormally, the growth of urban primary and secondary roads has been slow, and the average road length per vehicle has dropped from 9.7 m/vehicle to 2. 1 meter/vehicle, so the demand for parking spaces is in short supply.

In addition, the commercial and service functions of Dazhou City are too concentrated in the old city, which brings a little pressure on traffic demand and the city center cannot provide sufficient parking spaces. The main access roads between the old city and the west and south become congested sections, and the bridge head, intersection and backbone road conversion nodes become congested nodes. In solving the traffic congestion problem, Sanliping Ring Overpass in the south of Dachuan District and Tongchuan Qiaotou Pedestrian Overpass have been built one after another. But why is the traffic jam on Tongchuan Bridge still there?

"Managing traffic congestion requires systematic research, and it is impossible to just look at children." According to reports, the footbridge in the northern section of Tongchuan Bridge is located at the southern end of Tongchuan Middle Road, at the pedestrian entrance of Chaishi Street, crossing Tongchuan Middle Road, trying to alleviate the traffic congestion in Tongchuan Middle Road through the diversion of people and vehicles. "But the problem at this point has been solved, and the Indus beam has a new blocking point."

Therefore, Dazhou invites high-level professional organizations to formulate traffic improvement plans for the central city, systematically analyze the crux of urban traffic congestion, and propose short-,medium-and long-term solutions. Through various measures such as traffic demand management, streamline organization, order management, and transformation of important traffic nodes, the existing road traffic facilities will be fully tapped to improve traffic conditions. Due to the terrain, the traffic capacity of the river-crossing bridge in the main city of Dazhou is saturated, which has become a bottleneck restricting communication between groups. On the basis of eight existing bridges (including Jinnan Bridge), Dazhou will plan to build two bridges.

"In the central city of Dazhou, traffic pressure is mainly concentrated in Zhouhe Bridge, Hongqi Bridge and Tongchuan Bridge." According to reports, the load degrees of these three main river-crossing bridges all exceed 1.0. "The traffic flow of Tongchuan Bridge and Hongqi Bridge is three times the design flow".

According to reports, due to the natural limitations and spatial structure characteristics of Dazhou, the core traffic crossing the river into the old city accounts for 43% of the total traffic, and Dazhou will plan two bridges.

Chengdu Mountain Bridge will be built in Heshi Town, Dachuan District, on the planned "middle and vertical" main road across the state river. It is an important bridge on the main framework of urban traffic and an important channel connecting the chemical industry park and Jiangcheng logistics park. Yemaoxi Bridge across Zhouhe River is an important bridge to improve the regional road network, and it is another channel connecting Hujiaba area in the north and Sanliping New District in the south. It is connected to Yemao West Road in the north, Xianhe Road in the south and Tongan Road with four lanes in both directions. Dazhou will gradually realize the traffic pattern of three-dimensional interchange, and the expressway formed along the north bank of Dazhou will also contribute to the slow congestion and smooth flow of the city. This planning starts from Xiaohezui and ends at the intersection of Fenghuang Avenue and Chaoyang East Road along the river, with a total length of 6.5km, which makes the urban traffic smoother.

In terms of public transportation, the future direction is to develop rail transit. With the expansion of Dazhou city and population growth, the appearance of light rail and other means of transportation in Dazhou has been put on the agenda.

"The development of rail transit must be planned in advance". It is understood that in the long-term planning, Dazhou's rail transit has made route planning to open up the "meridians" of the city. According to reports, according to the plan, the traffic situation in Dazhou will strive to improve significantly in three to five years.
