Evaluation of DOTD�s Existing Queue Estimation Procedures |
摘要: |
The primary objective of this study is to evaluate the effectiveness of the Louisiana Department of Transportation (LADOTD�s) existing queue estimation procedures by comparing its output with that derived directly from site observations through video camera footage. Specifically the main objectives are to provide a detailed review of the state of practice of work zone closure analysis tools with particular emphasis on the current tools used by the LADOTD; acquire work zone lane closure models currently utilized on Louisiana�s freeways; identify specific work zone scenarios, and collect data on traffic flows and characteristics, delays and queue lengths; acquire corresponding queue analysis from current LADOTD queue estimation tools; and determine the effectiveness of the LADOTD�s Highway Capacity Manual (HCM)-based spreadsheet for queue analysis through comparative analysis of its data with that of the collected data. Also, determine whether the flat construction zone capacity if 1,309 pc/h/ln is a valid assumption. |
