Research on optimization of traffic organization in construction parks based on improved PSO algorithm
In order to solve the problems of low efficiency and high transportation costs in material transportation within the construction park,the comprehensive analysis of the material transportation process and the impact mechanism of traffic simu-lation within the park was conducted,then the comprehensive model of on-site traffic simulation was constructed,and the col-linear transportation scheme of road in the construction park was solved.Taking the foundation pit areas of 02B and 05B in the construction park of Beijing Urban Sub-center Station as the research object,the multi-angle feedback modified PSO algo-rithm was used to solve and analyze the optimized results.The results show that the material transportation path before and af-ter road public transportation change,the frequency of 85% road traffic density set after road public transportation increases by 5%~20%,and the frequency of 85% traffic density on key optimized congested roads decreases by 10%~40%.The pri-vatized roads change from the second-level service level to the first-level service level,which promotes the utilization of trans-portation resources,thereby reducing transportation costs and improving the overall efficiency of material transportation in the park.The research results can provide theoretical reference and experience for the optimization of traffic organization in closed management areas of other construction parks at home and abroad.
