Decision-making Model of Roadside Safety Improvement on Two-lane Highway

In order to meet the needs of scientific decision-making of roadside safety improvement project, a decision-making model of two-lane highway roadside safety improvement is proposed which based on Game Theory analysis. Firstly, roadside safety level was divided by indicators which can reduce the probability of run-into-roadside or improve the safety of roadside objective characteristics, and each indicator safety classification standards was determined on the basis of certain statistics data. Then, countermeasures database of roadside safety improvement is established by summarize and refining the roadside safety conditions countermeasures based on the domestic and overseas research results. Finally, against Game problems for roadside safety improvement process, and carried out the analysis of conflict and cooperation about the Game problems, decision-making information fusion model of roadside safety improvement is proposed by Game Theory. The results can provide a decision-making method for roadside safety improvement program.
