Turning movements are done by portable traffic recorders or manual counting procedures. Vehicle Classification Vehicle classification data is collected to determine the breakdown of the types of vehicles on Connecticut s roads. Vehicles are stratified into 13 categories ranging from motorcycles, to passenger cars, to buses, to trailer trucks, to multi trailers. Vehicle classification data is collected at approximately 100 locations and allows the development of factors to estimate vehicle classification data by roadway type and traffic volume. Truck Weights A growing area of importance for transportation planning is truck statistics.
Trucks are a critical component of pavement wear.
Understanding the number and weight of trucks on our roadway system plays a major role in scheduling and planning of pavement reconstruction and repaving. The weigh in motion program provides these statistics. Major technological advances in the past few years now allow us to develop statistics on truck traffic without stopping or inconveniencing truckers. Trucks are classified and weighed as they pass over sensors on or cut into pavement.
