Abstract
A measuring vehicle for roadways comprises a tow vehicle and an instrument carrying vehicle connected for movement to the tow vehicle. The connection between the two vehicles includes a periodically operative lost motion arrangement so that as the tow vehicle moves continuously along the roadway, the instrument carrying vehicle automatically remains stationary periodically. The connection between the tow vehicle and the instrument carrying vehicle advantageously comprises a connecting rod connected at one end to the instrument carrying vehicle and at its other end to an endless belt or chain revolving on guide means such as rollers or sprockets whose rotational speed is proportional to the speed of the tow vehicle.
