Road and Traffic Kistler measuring technology not only contributes to the active and passive safety of vehicles but also helps to protect roads against overloaded vehicles. Overall weight is not the sole factor. Damage to road surfaces and substructure comes mainly from excessive wheel and axle loads, stress is increasing to the fourth power of the wheel load. The Kistler WIM ("Weigh in Motion") system allows axle loads to be determined as vehicles drive past. Thanks to WIM, overloaded vehicles can be taken off the road promptly, thereby preserving the road surface, avoiding expensive maintenance work and traffic congestion and increasing road safety. Road surfaces Application Kistler Lineas force sensors can be incorporated into all standard road surfaces. The elastic properties of Lineas sensors and their response to abrasion correspond largely to those of the road surface itself. This is important because the quality of a WIM system equally depends on how well the sensor characteristics conform to those of the roadwear characteristics. Use/purpose · Road surfaces and substructures need to be protected against overloaded and badly loaded vehicles · Repairs are not only costly but also result in traffic congestion · The recording and elimination of overloaded or wrongly loaded vehicles results in a long term improvement in traffic safety Weight measurement Application In tire research, dynamic measurement of wheel load distribution is an important means of assessing force and pressure distribution within the tread contact. It is also important in road building research to investigate the factors involved in serious damage to the road surface. Modulas sensors are indispensable for road surface management systems and for research into related phenomena such as cracking and rutting.
