After the highway was opened to traffic , with the continued growth in traffic , the operator time goes on , the highway and its supporting facilities of varying degrees of damage and aging , caused by lack of capacity , service levels . Which requires them to maintain or restore , but it is the impact of these construction jobs , job zone sections decrease in the number of lanes , and there are complex vehicles running state workers , construction machinery , the roadside construction fence between vehicles constitute a dangerous and complex traffic environment , is a very easy to induce sections of traffic accidents and traffic congestion , traffic safety situation is very grim . Therefore , to carry out the operation area of highway safety and security technology has important practical significance . In this paper, on the basis of the analysis of domestic and international status quo , the problems that exist today , and we need to study the main content . First, an overview of the highway definition of the operation area and the type of divided , and the operation area , vehicle , road and traffic flow characteristics of the system analysis , hazardous characteristics and safety hazards of the highway work area . Secondly reasonable method of calculation of the length of the highway construction operations in the warning area , the transition zone , buffer zone , work area and termination area analysis , and explore the different highway construction phase of the operation area layout . According to the characteristics of highway construction jobs , research work zone traffic signs and markings , guardrail settings , temporary isolation facilities and nighttime construction safety facilities and other settings . Finally, with reference to the existing general highway construction road traffic organization programs , fully consider the characteristics of highway traffic , construction scale and safe driving demand factors analysis research program of highway construction work zone traffic organization , illustrate the renovation and expansion construction traffic organization program design. The first paper presents the theoretical analysis of the work area on the basis of the Jiangxi Provincial Communications Department projects \
