Problems solved by technology

[0002] At present, the urban transportation security system can only obtain the current transportation status, but cannot analyze and predict the future transportation situation, so as to avoid it in advance
When the road is congested, the commander can only spend a lot of time and energy to check and analyze the cause of the congestion, and dispatch vehicles according to experience or temporarily, resulting in untimely dispatch and reduced accuracy. What's more, the vehicle may not be able to turn around and the plan cannot be planned. went smoothly

Embodiment

[0119] According to a preferred embodiment of the present invention, a parallel simulation-based urban traffic transportation support system design and implementation method includes the following three parts, combined below Figure 1 to Figure 8 As shown, the implementation process of this embodiment is described in detail.

[0120] With the background of urban transportation security, using the idea of ​​parallel simulation, an urban transportation security support system based on parallel simulation is constructed. The platform is mainly composed of two parts: the urban traffic security system and the parallel simulation system. The parallel simulation system obtains real-time transportation information from the urban transportation guarantee system, and establishes and improves the physical simulation model, including vehicles, GPS, roads, etc. Through the ultra-real-time simulation operation of the model, combined with terrain, weather and other information, the vehicle l...

Abstract

The invention provides a parallel simulation-based urban traffic and transportation support system. A simulation system running parallel to a traffic and transportation guarantee system is built; through interconnection and information interaction with the actual system, the simulation system continuously obtains the latest transportation condition from the traffic and transportation guarantee system, builds entity simulation models, performs transportation condition analysis and scheme optimization through super-real-time simulation operation of the models and feeds results back to the urban traffic and transportation guarantee system; guarantee schemes can be generated continuously and circularly and expected effects of the schemes can be deduced and estimated. The system greatly shortens transportation dispatching time, greatly improves the dispatching accuracy and provides a new thought for building a parallel simulation system for decision support.

Description

technical field [0001] The invention belongs to the technical field of decision support for urban transportation, in particular to an urban transportation support system based on parallel simulation. Background technique [0002] At present, the urban transportation guarantee system can only obtain the current transportation status, but cannot analyze and predict the future transportation situation, so as to avoid it in advance. When the road is congested, the commander can only spend a lot of time and energy to check and analyze the cause of the congestion, and dispatch vehicles according to experience or temporarily, resulting in untimely dispatch and reduced accuracy. What's more, the vehicle may not be able to turn around and the plan cannot be planned. went well. Contents of the invention [0003] Aiming at the problems and deficiencies existing in the current urban transportation support system, the present invention proposes an urban transportation support system b...
