Improving Our Understanding of How Highway Congestion and Price Affect Travel Demand (SHRP 2 Prepublication Report*)
|
|
Greetings!
Over the past 30 years, a large body of research has been carried out to better understand and predict how traveler behavior changes in response to fluctuations in traffic congestion and in the price of travel. The objective of SHRP 2 Project C04 (Improving Our Understanding of How Highway Congestion and Price Affect Travel Demand) was to synthesize that research to select the most important and well-founded behavioral hypotheses, and then to test those hypotheses statistically on data sets in the United States. The results are documented in the final report, which is intended for those who carry out or direct modeling into highway congestion and pricing policies, and for planners and decision makers who would like to gain a deeper technical appreciation and understanding of particular issues.
* To make research available as early as possible, SHRP 2 is temporarily posting final reports that have been submitted by the research team, reviewed according to the relevant National Academy of Sciences procedures, and accepted for publication. These prepublication drafts, which have not been edited or formatted for publication, will be replaced by the final versions as they complete the editorial process.
