Embodiment 1

[0038] In this embodiment, the tunnel traffic guidance scheme is as follows figure 2 As shown, the main line of the tunnel adopts fully enclosed construction, and the current road 3 in front of the storefront on the east side of the main line is used as the non-passenger road for this section.

[0039] Step 1. First, data collection: Obtain the basic traffic flow information of the construction road section by using drone aerial photography, surveillance cameras and traffic detectors, and record the types and driving speeds of vehicles passing through the construction road section at different times through on-site surveys. Road A, Road B and Road C are two-way six-lane, the single-lane traffic volume is 10,000 vehicles / d, and the driving speed is 60km / h~80km / h;

[0040] Step 2. Generate the surrounding real terrain model of the project location in OpenRoads ConceptStation software, such as image 3 shown;

[0041] Step 3. Construct a three-dimensional road model in OpenRoa...

Abstract

The invention discloses a bidirectional traffic guidance and modification simulation method based on BIM and VISSIM microscopic simulation. The method comprises the following steps: data acquisition; generating a live-action terrain model around the position where the project is located in OpenRoads ConceptStation software; constructing a three-dimensional road model in OpenRoads ConceptStation software according to a live-action terrain model and a traffic guidance and modification map, and preliminarily designing parameters; importing the generated three-dimensional road model and the collected data into VISSIM software, and carrying out microscopic traffic simulation; and guiding the model generated by the VISSIM software back to the OpenRoads ConceptStation software, and carrying out traffic guidance and modification simulation. According to the method, the relationship among people, vehicles, roads and environments can be better reflected on the basis of a traditional microscopic simulation technology, and optimization and decision making of a traffic guide and change scheme are facilitated.

Description

technical field [0001] The invention relates to a micro-traffic simulation technology, in particular to a two-way traffic guidance simulation method based on BIM and VISSIM micro-simulation, which is suitable for ground traffic guidance simulation during tunnel construction. Background technique: [0002] The construction of the tunnel will occupy a lot of road resources, and the existence of the construction area often squeezes the non-motorized vehicle lanes, which will definitely greatly affect the original roads and traffic conditions nearby. Therefore, carrying out traffic guidance reforms in the tunnel construction area and surrounding areas, and properly handling the contradiction between tunnel construction and road traffic can improve the unfavorable traffic conditions during the construction process, ensure the orderly progress of traffic during the tunnel construction period, and ensure the smooth operation of the tunnel construction. The impact on road traffic is...
