Study On Safety Facilities Of The Construction Sections For Overhaul Of Freeway

At present, expressway gradually entry into period of the overhaul and reconstruction inour country.the result is a lot of traffic organization problems of traffic organization in worksperiod an words section,such as traffic congestion and many traffic accidents. So, it is urgentto study the smooth-traffic project evaluation for overhaul of expressway.This thesis entirely analyses domestic or aboard researches and engineering. Proposedadd analyzed organizational framework for the traffic organization of works, to solves theproblem of smooth-traffic in works sections. According to the thorough investigation materialand unified the theory has carried on the analysis to the thorough investigation material andunified the theory has carried on the analysis to the expressway construction road section, andhas carried on the transportation simulation.Through compare and analysis on project evaluation targets system, saturation degree,average speed, speed deviation, traffic density and average travel delay of works section aredefined to be evaluation targets,and given the scope of the evaluation targets value.
