The present study is a research on the attempt with long heavy goods vehicles on German motorways. The attempt started on 01 (th) January, 2012 based on a special traffic ordinance. The ordinance provided a scientific program managed by the German Bast. The study analysed effects of the new vehicles at the traffic quality, traffic safety and new standards for geometrical design. The potential impacts that the long vehicles could have on roads, carriageways on junctions and interchange points, gateways, driveways, weaving lanes, parking in emergency rest stops (in tunnels) and parking on rest areas was also evaluated. The purpose of this study gives answers of the questions of area required, handling and geometrical requirement. The study worked with follow shot by the measuring vehicle (called UNO), photogrammetry attempt, cameras at the trucks and a laser scanner for the measure at the parking areas. The photogrammetric helps to understand the driving lines of the different long-vehicles. The follow shot by the measuring vehicle and the laser scanner help to compare to a long heavy goods vehicle with a conventional heavy goods vehicle. The study shows that long heavy goods vehicles don’t have problems in carriageways on junctions and interchange, weaving lanes, access and exit lanes. If a long heavy goods vehicle turns right into an overriding road it overruns the left turn lane there. Long heavy goods vehicles (25.25m) aren’t able to park in emergency rest stops. The parking on rest areas is only possible through overriding the neighboring parking lot. (Author/publisher)
