Abstract: Introduction. The implementation of the Weighing in Motion System (WIM) in Ukraine has been started in compliance with the State Targeted Economic Program for the Development of Public Highways of State Importance in 2018-2022 and was aimed at preserving the road surface from damaging and reducing expenses for road maintenance. In order to ensure transparency in the field of state planning for the road construction, reconstruction and repair, Ukravtodor ensures the publication of up-to-date WIM information vi… Show more

Introduction. The practice of charging road tolls to compensate for the costs of the road construction and operation has been known since ancient times. The traditional approach to toll collection on motorways is that vehicles must stop and pay at the appropriate collection point (Toll Collection Plaza — TCP). At the same time, two payment systems are traditionally distinguished: an open one, in which the driver pays for traveling the entire toll section, and a closed one, in which, upon entering the toll motorway, the driver is obliged to take a ticket at the first point (station) of payment and return it upon exiting the motorway at the final payment point, paying for the actual distance traveled. In both systems, there are bound to be vehicle delays in TCP. In this regard, transport engineers and road design specialists face several urgent tasks, such as determining the impact of toll booths on the level of service, capacity and other traffic indicators on motorways, assessing the impact of TCP configuration and toll collection technologies on of the traffic flows indicators in the TCP zone and in the transport network. Problem statement. One of the modern methods of research and assessment of the state of traffic at toll collection points is microsimulation of the road network or individual TCPs. At the same time, the reliability of this analysis tool will be determined not only by the calibration parameters of the simulation model, but also by the quality of the adopted distribution of traffic flows. Purpose. The purpose of the work is to substantiate the method of traffic flows distribution when developing a microsimulation model of toll collection plazas via PTV Vissim software. Materials and methods. Single TCP scenarios are simulated in Vissim, which differ in the number of operation lanes, approaches to network reproduction, and applied traffic distribution methods. The results. The actual scientific and applied problem of justifying the method of traffic flows distribution in the microsimulation of toll collection plazas in PTV Vissim has been solved. An analysis of the possibilities of traffic reproduction methods in TCP using static routes, dynamic assignment, the PTV Vissim COM interface for dynamic assignment, “Managed lanes” routes was performed. In TCP models with the number of lanes from 3 to 6 with static routes and dynamic assignment, the realistic behavior of drivers when choosing a traffic lane in TCP is verified. An analysis of transport delays in TCP models was performed to compare the simulation results when using static routes and dynamic assignment.

Introduction. The introduction to the paper highlights the general role of the weight control of motor vehicles on roads by WiM – methods (Wegh-in-Motion) in the assurance of the traffic safety and in the transportation infrastructure preservation. Problem statement. The issues of the paper concern the problems of implementation of contemporary technologies of the High-Speed WiM (HS-WiM) where the conditions of the measurements of the loads from the vehicle generate high measurement error. Purpose. The main goal of the paper is to perform an analytical review of methods of the weight control of vehicles and of competitive aspects of existing WiM technologies and also the analysis of the practice of WiM application. Results. The analytical reviewing led to the following results: it was revealed that the basic principle of WiM systems operation consists in determining the dynamic wheel/axle loading of a vehicle transmitted to the pavement; data thus obtained shall be used to reveal the overloading. Modern WiM systems give possibilities to obtain data concerning axle number, axle spaces, vehicle length and speed, axle (or wheel) dynamic loading, number of equivalents of standard axle loading, and also data regarding the traffic flow characteristics; it was concluded that WiM systems can be divided into two main types: the systems operating at low speed of a vehicle (up to 15 km/h, LS WiM) and those operating at steady speed of the traffic flow (up to 130 km/h, or high speed, HS WiM). LS WiM ensure the accuracy of the measurement in a range from 3 % to 5 % and belong to the methods of weight control of motor vehicles approved by the legal metrology as well as the static weighing does. HS WiM control is more sensitive to the external factors due to the effect of a vehicle dynamic and thus cannot assure the above stated accuracy of measurements, moreover, cannot assure the appropriate accuracy for the satisfactory number of trucks. HS WiM systems are not approved by the legal metrology; factors affecting the accuracy of measurements in HS WiM systems were analyzed. It was revealed that the effect of a vehicle dynamic on the measurement error can be mitigated assuring the compliance of the road pavement surface condition with the standard requirements mainly with those concerning pavement surface roughness.
