摘要：	The Texas Department of Transportation (TxDOT) currently has very limited count data on pedestrian and bicyclist usage of the transportation system. The first objective of this project was to recommend a count monitoring process for pedestrians and bicyclists that can be sustained statewide. The second objective was to develop a consolidated database of pedestrian and bicyclist counts from two pilot cities, as well as readily available pedestrian and bicyclist count data from other locations. Researchers evaluated options for permanent and portable counter equipment, and recommended a combination of equipment and locations for both permanent and short-duration counts. Researchers then demonstrated the installation of both permanent and portable counter equipment in Austin and Houston. In an evaluation of crowdsourced data, researchers found that crowdsourced data represented a small (less than 1 percent at some locations) and biased portion of all pedestrian and bicyclist trips, varying widely by data source and location. Further study is needed to develop a systematic expansion process that can be used to estimate total pedestrian and bicyclist counts on different facility types from the crowdsourced data samples. Also, researchers developed a consolidated database that included 350 unique pedestrian and/or bicyclist count locations in 11 cities, of which 84 were permanent continuous count sites and 266 were short-duration (e.g., at least seven days) count sites. The database included a standardized data dictionary that is consistent with the Federal Highway Administration’s Traffic Monitoring Guide, but also included additional attributes that were deemed necessary for TxDOT and other agency monitoring needs in Texas.
