Abstract

In this paper the development and off-line testing of a procedure for estimating the current capacity at a motorway carriageway are described, the adjective 'current' referring to prevailing roadway and weather conditions. Such a procedure is important for dynamic traffic management applications, such as ramp metering and rerouting which crucially depend on reliable estimates of current capacity. The procedure is specifically aimed at estimating capacity while the traffic is still free-flowing. It is based on the combination of on the one hand an on-line estimate of the 'current' Fundamental Diagram, and on the other hand the maximal occupancy of a loop detector that may be achieved at a carriageway under free-flowing conditions. Suitable representations for the Fundamental Diagram and the maximal occupancy are based on investigations using a large set of data, reported in an earlier paper. The on-line procedure itself is developed and tested for different sets of weather conditions. Good responses of the procedure to changing weather conditions (dry/wet) have been obtained. It is concluded that the procedure offers promising perspectives for eventual application in dynamic traffic management systems. Suggestions for future research are given.
