Problems solved by technology

[0003] Existing traffic simulation platforms are mostly oriented to a single traffic mode, and there are few studies on how to build a simulation platform under the condition that multiple traffic modes coexist in an integrated transportation network
Moreover, most of the existing simulation systems are single-threaded systems, and the simulation speed is relatively slow, which cannot adapt to the real-time connection with the business system.

The technology is characterized by comprising a regional comprehensive traffic and transportation network emergency simulation framework, a demand estimation and prediction model based on combination of trend prediction and a neural network and an agent-based multi-mode comprehensive transportation network simulation model. According to the comprehensive traffic network operation situation detection simulation technology facing the road and railway networks, by means of exiting road network and railway network traffic data, an overall framework of a regional comprehensive traffic and transportation network emergency simulation platform is constructed in a focused mode, a time-space network modeling technology is applied, and an agent-based multi-mode comprehensive traffic simulation model is constructed.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and specifically relates to a deduction and simulation technology for the running situation of a comprehensive traffic network oriented to highways and railway networks. Background technique [0002] In the process of regional emergency response, how to formulate an emergency traffic organization plan for a comprehensive traffic network to ensure safe, efficient, and orderly operation of emergency traffic is of great importance for improving regional emergency management capabilities and reducing casualties and property losses caused by disasters. Practical significance. For a transportation network, especially an integrated transportation network, it is difficult to quickly obtain its operating status changes under event conditions and the intuitive effects of different control measures or emergency response measures through mathematical calculations. Therefore, it is an important mean...
