Abstract
Case studies about using Mobile Mapping System (MMS) on traffic network mapping

This presentation contains three different case studies about using MMS on projects related to transportation networks. The MMS is one of the most recent systems; a Riegl VMX-450 equipped with two rotating laser scanners, GNSS receivers, IMU and DMI and can measure up to 1.1 million points per second. The first project is about clearance checking in one of the longest tunnels of Central Europe, the Karawanks Tunnel. The tunnel is about 8 km long, and the transportation authority asks detailed and precise cross sections to check if an oversized vehicle can go through the tunnel safely. Because of the final result required only relative accuracy, we don’t need to take care about the absolute accuracy, but we used different solutions to check how we can provide best absolute accuracy as well. The second project is about mapping the overhead cable system of a railway station which has more than 30 rail tracks without disturbing the traffic. The measurements were done with the same MMS, installed on a convertible rail/road car. The measurement was finished within four hours, and provided much more information with incomparable higher safety than a conventional survey can do. The third project is about how to check the side slopes on hundreds of kilometers of a highway without disturbing the normal traffic. The measurement was done with the Riegl MMS again, but we used some automatic and semi-automatic processing solutions to achieve the vector extractions and derived side slopes within some days for a quick warranty check.
