Study On Facilities Layout And Scale Adjustment Of Freeway Service Area

Service facility is an important part of freeway, which is one of important facilities toassure the safety, expedite, convenient and efficient operation of freeway. It is aconvenient place to provide service for meeting basic physiological, psychological needsof drivers and conductors in the long journey, meeting the refueling and maintenancedemand of the vehicles. Service facility shows the civilization degree of high gradefreeway industry. Service facility provides service directly to drivers and conductors,indirectly to the whole society. Strengthening the operation and management of servicearea can not only bring economic benefit to the enterprise, but also bring social benefit.The building of freeway service facilities is related to the development of economy andsociety, the consumption idea, traffic flow, and traffic composition. The development ofeconomy and society, the improvement of life quality and the rapid growth of trafficvolume put forward higher request to give full play to the freeway service function,improve the service level. Along with the rapid economic development of Jilin province,the transportation industry develops rapidly, freeway traffic volume grows rapidly, as aresult, current existing freeway service areas can not meet the requirements, the freewayoften closed in wind or snow weather, the vehicles retention in service area occursfrequently, and retention time is long, staff are complex. Due to the small scale of theservice area, retention space and using facilities are shortage, which often cause confusionparked. In peak time, vehicles already queue up on deceleration, even on freeway, driversand conductors complain bitterly. During vehicles retention time, the service area need toprovide food, drugs, and fuel to drivers and conductors and vehicles, and also need toprovide accommodation to drivers and conductors. But, at present, because partial servicefacilities are not perfect and unable to set enough facilities, service quality declinesseriously, and the normal functions of service area are influencedIn view of the current problems of existing service facilities in Jilin province thatservice facilities area is too small, parking area is insufficient, function distribution isunreasonable or not perfect, and the traffic jam during rain and snow whether and trafficpeak hours and so on, choosing a part of Jingha freeway within the territory of Jilinprovince as the research object, the traffic flow forecast method, freeway service area thelayout and the scale adjustment methods were studied in this paper. First of all, theresearch content and method were determined by clearing the research background,research purpose and meanings. The development of economic society in Jilin provincewas introduced, the current situation of economic and social development trend was deeply analyzed. On that basis, the current development situation of transportation wasexpounded in detail, the development of various transportation modes were expoundedrespectively and the level of traffic volume and features were analyzed. Secondly, aspecific thinking was given according to the deep analysis of the characteristics offreeway traffic flow forecast, and appropriate forecasting model was chosen by comparingcommonly used prediction models. And on that basis, traffic flow of researched freewaysection was forecasted. Again, the classification of freeway service area and the facilitiescomposition were introduced, and the service area layout principle was expounded.According to the forecast results of traffic flow and the related standards, the scalestandard of service area was given. Choosing Siping to Changchun and Changchun toLalinhe sections of Jingha freeway as application object, service layout and scaleadjustment were conducted. Finally, the influences brought by layout and scaleadjustment of freeway service area to social were deeply analyzed, and the suggestionswere given combined with actual situation.
