摘要
The international and national forecasts road transport development is optimistic,and they should promote implementations of innovations in road infrastructure.The producers of heavy vehicles and their users aim to increase total vehicle weights and axle loads.International organizations:the Joint Transport Research Committee(JTRC)and the Forum of National Highway Research Laboratories(FEHRL)study the influence of increased loads on road infrastructure and define the directions of innovative solutions for trucks and the road infrastructure.The number of registered vehicles has been growing in Poland.The reliable part of heavy vehicles is overloaded and they cause considerable damage to roads and influence traffic safety.The degradation of roads results from unacceptable axle loads and the total mass of heavy vehicles.It is necessary to introduce the weigh-in-motion system in Poland for pre-selective weighing of vehicles.The system will measure axle loads,number of axles,vehicle length and calculate its mass without stopping.For the identification of vehicles,the intelligent system ISKIP may be used,developed by the Road and Bridge Research Institute.The weigh-in-motion system is under implementation in Poland.
