Study Impact New Traffic Management Technique

Over the past 25 years, a variety of new traffic management techniques have been introduced, including dedicated traffic lanes. Although these techniques hold promises for relieving congestion, it is important to understand the safety implications of adopting such procedures. The objective of this study is to determine the safety impact of these techniques and to recommend approaches that can be taken in designing traffic management techniques that minimize safety risks. This study would use advanced traffic simulation models, supplemented--where possible--with historical data, to analyze impacts of changes in traffic flow resulting from congestion pricing an changes in weaving movements resulting from dedicated traffic lanes, and reductions in truck-car lane sharing due to truck-only lanes. The study would include not only the period or location in which the technique is in effect but its safety impact on the highway outside the time period or spatial location of the restriction.
