Projects
Traffic Simulation for the Street 'Heerstraße' in Berlin (Germany)
Scope of Business: Transport Engineering
Focus: Traffic Surveys
Client: Berliner Verkehrsbetriebe AöR (BVG)
Project Term: 2006
Project Location: Berlin
Project Description
With this project it has been shown that by the method of traffic simulation a measurement of the success of acceleration measures is possible in retrospect. A process of this type requires an analysis of the current traffic situation and the conditions before the acceleration process (beforehand-state).
The object of analysis was represented using a simulation model for the morning rush-hour, traffic during the day and evening rush-hour separately because of significant differences in traffic flows. The model - consisting of nine light signal-controlled junctions - was calibrated using the existing conditions. The subsequent integration of the light-signal system (LSS) regulation as it was beforehand allowed testimony about what the traffic conditions could have been like if the acceleration measures had not taken place. Based on identified quality indicators a declaration could be made about the economic effects of the bus acceleration measures.
VCDB's Scope of Services
- Development of the project approach and further development of the project idea with the staff of the Berlin transport company (BVG)
- Setting up the simulation model using the program VISSIM
- Traffic surveys (instruction and training of survey personnel, quality assurance by monitoring the traffic survey, plausibility of data and graphical representation of traffic flows)
- Integration of the current public transport and the current flows of individual motorised traffic into the model
- Representation of the LSS regulation of the current situation and the previous digitalised regulation of the former situation
- Measurement of the success of the acceleration measures
- Deductions from the findings of the pilot investigation
