DOiT Dynamic Optimization in Transportation. Ragnhild Wahl, SINTEF (Per J. Lillestøl SINTEF). Background. Many transporters have a high degree of dynamics that requires an on-line/operative VRP-solver: Transportation orders (occurrence, properties) Fleet status (break-down, etc.)

DOiT Dynamic Optimization in Transportation
Ragnhild Wahl, SINTEF
(Per J. Lillestøl SINTEF)
All these areas contain dynamic and uncertain information
This is sub-optimal
In sum, these factors reduces the possibility for efficient use of resources through advanced transportation planning.
Floating Car Data is a term that is used to describe continuous data collection from a moving vehicle.
FCD is a general term for several different traffic data. However, we often mean travel time when we speak about FCD.
Sensors and techniques to collect FCD varies. The most common technology for collecting FCD is GPS.
We have searched for similar projects, and we found several different test projects. The most interesting projects for us were:
2. Positions are collected at a fixed frequency, but only single point data is being collected and stored
3. Time and vehicle identification are being collected at predefined positions, and a continuous log is being stored for each vehicle
