  In 1997 Finland and Sweden jointly invested in a Heavy Vehicle Simulator, HVS, from South Africa. After the first period in Finland the HVS-NORDIC was moved to Sweden and VTI in Linkoping in September 1998. A program for research co-operation in the area of accelerated pavement testing has been agreed between Finland and Sweden covering the years 1997–2003. The general objective of the research co-operation is to learn more about pavement response and pavement performance. A second but most ...[more]
Effects of winter road maintenance     4.5 4486 01.04.2010

Real-Time Video Relay for UAV Traffic Surveillance Systems Through Available Communication Networks     0 2407 06.07.2010
  The unmanned aerial vehicle can be an efficient and economical solution to real-time surveillance of highway traffic. This paper describes a data link that connects the camera onboard an unmanned aerial vehicle to the monitoring terminals in the office of the Michigan Department of Transportation. A video signal captured by the surveillance camera can be either displayed on the terminals in real time, or stored on ground for future off-line analysis. The video signal is relayed via available mo ...[more]
Use of Unmanned Aerial Vehicles in Traffic Surveillance and Traffic Management     0 2482 06.07.2010
  The ATSS study somewhat demonstrated an innovative approach to apply ITS technology through surveillance, data collection, and data transmission. Use of UAVs in data collection and other tasks can be expected to dramatically improve traffic management and incident management, forest fire surveillance, and law enforcement initiatives. Lessons learned can be utilized by a variety of agencies as they expend resources to manage transportation, emergency management, disasters (both manmade and natur ...[more]

VMS harmonisation in Europe     0 2390 13.07.2010
  Background Variable Message Signs (VMS) inform road users and manage traffic flow. They are becoming more widespread and are growing in importance. While primarily designed to serve the nationals of each country, VMS need to be understood by road users of all nationalities to be fully effective. Also needed is a continuity of operation across state boundaries. Increasing use of the network and further developments in network operation will increase the pressure to develop a strategy for dealing ...[more]
