Analysis And Research On The Influence Of Canceling Provincial Border Toll Stations On Expressway Vehicle Operation

Since January 1,2020,China has completely completed the policy task of abolishing toll stations on the provincial boundaries of expressways.The traffic process and operation characteristics of vehicles at provincial boundaries of expressways will change significantly,and the traffic efficiency of vehicles will be improved to some extent.However,the specific impact mechanism of canceling provincial boundary toll stations on vehicle operation is still unclear.Therefore,this paper explores the quantitative impact of canceling provincial boundary toll stations on vehicle operation,and consequently to,provides reference evident for expressway operation management,traffic policy formulation and driver’s travel choice,and at the same time provides scientific criteria and data support for which the expressways to realize comprehensive free-flow tolling.Firstly,this paper teased the relevant literature at home and abroad,unscrambled the relevant policies and technical standards of the industry,analyzed the infrastructure layout’change and technical paths of withdrawing stations before and after canceling the provincial boundary toll stations,and put forward the influence of this policy on the traffic process of vehicles at the provincial boundary of expressways.Secondly,SQL server was used to process the networking data of provincial boundary toll stations,and combined with the survey data of provincial boundary toll stations,analyzed the proportion of inter-provincial traffic flow,the number of the distributation of inter-provincial,indicators such as proportion of vehicles with different charging methods,vehicles speed and service time,and the temporal and spatial characteristics of traffic flow of provincial toll stations on ordinary working days and free holidays were extracted.Finally,based on the traffic characteristics of provincial boundary toll stations,the T-save model for vehicles after canceling provincial toll stations was established,and the calculation method of energy saving and emission reduction was established based on transit time,and defined the transit speed at provincial boundary.Took the vehicles at the peak hours of Lubei provincial boundary toll station as the research object,the case calculation of transit time and fuel consumption emission impact was carried out,and the saved transit time was empirically studied by using highway toll data,the entropy method was used to evaluate the comprehensive impact of the policy on various vehicle types at the provincial boundary.The research results shows that vehicles can effectively save transit time and achieve remarkable energy-saving and emission-reduction effects after canceling provincial toll stations.In terms of transit time,Lvtong vehicles can save at least 400 s,and the transit speed at provincial borders can be increased by more than 70%.MTC vehicles and ETC vehicles can save about 170 s and 130 s respectively,and the transit speed at provincial borders can be increased by 28.39%～48.86%.The impact on MTC trucks during free holidays is far greater than ordinary working days.It can save transit time about 480 s,increase traffic efficiency by4.36 times,and increase traffic speed at provincial borders by at least 81.69%;In terms of fuel consumption emissions,fuel consumption emissions can be reduced by 66.63% during peak hours,and fuel consumption emissions can be reduced by more than 91.92% when the traffic volume per hour is close to the maximum service traffic volume;The evaluation finds that canceling provincial boundary toll stations has the greatest impact on MTC6-axle trucks,followed by Lvtong vehicles and Class I buses,and has the least impact on ETC2 buses.
