Simulering av tätortstrafik med CONTRAM8: tillämpning på Östra Länken i Linköping
Swedish National Road and Transport Research Institute.
2008 (Swedish)Report (Other academic)
Abstract [sv]

CONTRAM (Continuous Traffic Assignment Model) is a computerised model for simulation of traffic flows on roads and streets. The model makes it possible to study effects of traffic management schemes or future developments of the street network. CONTRAM results are based on simulations at the meso level. The smallest unit is a group or "package" of vehicles with origin-destination between two geographical points. A "point" is an approximation of a geographical area, for instance an area with housing. The overall objective was to use the CONTRAM software for a traffic problem in Linköping. After discussions with Linköping Municipality, the Braskens bro area was chosen with the planned development of an eastern by-pass "Östra Länken" (the Eastern Link). The main interest of the Municipality was the second of the two steps: a) modelling of the existing situation and b) estimates of how planned road developments will affect traffic. More specifically, the Municipality wanted to know how the developments will change the traffic flow level on the heavily used Braskens bro, which for short time intervals sometimes can be oversaturated.
