چکیده
Integrating fixed and mobile roadway data 2 ABSTRACT Fixed-site and mobile data sources have distinct strengths for representing roadway conditions, and unique insights can be generated by combining the two. Ongoing research on an urban arterial roadway corridor combines distinct data sources for multi-criteria transportation facility performance assessment. The roadway is instrumented with an adaptive traffic signal system collecting signal phase and vehicle count data and mid-block radar detectors recording high-resolution vehicle counts, speeds, and classifications. Transit buses on the corridor record stop-level vehicle position and passenger activity data, and air quality has been measured with deployable roadside monitoring stations and a portable multi-sensor device for travelers. Combinations of these data sources provide new insights about performance of the transit signal priority (TSP) system, relationships between signal operations and roadside air quality, and variations in on-road exposure concentrations.
