Study On Operation Information System Of Freeway Under Adverse Weather

This passage based on the project in accordance with the actual Yu-Wu Highway issues, accord questionnaires, collecting and analyzing relevant information and on-site observation etc,to analyze the main information system users and user needs, combining cognitive psychology, traffic psychology, traffic engineering, road works knowledge,bring forword the minimum distance algorithm, foggy highway district board to establish the location of variable intelligence algorithm and variable information board set up strategies based oncognitive psychology. Constitute the highway fog district location variable information board recommended the establishment of standards.Relying onWu Yu highway, according to the location of variable information board recommended the establishment of standards, optimize the allocation of the based on variable information board,at the same time investigate the number of words, scope and frequency of VMS refresh key information technology systems relying on the project based on the variable information content of the publication of information board. Finally, the paper establish Chongqing highway information system.Through the system,road user can query Chongqing weather road traffic information, road maps of Chongqing browsing and spatial analysis, and the system provide users with a good road trip of the reference services.
