Alameda County Transportation Commission (Alameda CTC)
Multimodal Performance Monitoring of the Alameda County Transportation Network (2020-2024)
Project
As a member of a project team, ETG assisted the Alameda County Transportation Commission (Alameda CTC) with its multimodal performance monitoring of the Alameda County transportation network for a total of three cycles – 2024, 2022, and 2020.
Our Work
An implementation plan was developed first to specify the methodology to be used for collecting, analyzing, and presenting data during each of the monitoring cycles. ETG led the transit and active transportation tasks and supported all other tasks.
• Transit: Used Automatic Vehicle Location (AVL) and running time data to perform analysis for the 146-mile trunk transit monitoring network within the Alameda County, including average transit speed, average transit speed to average auto speed ratio, and peak-to-off-peak transit speed ratio. Performed trend analysis by comparing with previous cycles of data.
• Active Transportation: Collected bicycle, pedestrian, and scooter counts, and compared counts with the previous cycles of counts for a total of 150 intersections within the Alameda County. Analyzed bicyclist travel behaviors, including helmet use, sidewalk riding, and wrong-way travel.
• Freeway & Arterial: Used INRIX data to perform speed, delay, and LOS analysis for over 500-mile freeways and arterials within the Alameda County. Performed a time-series trend analysis showing changes in performance measures over time.
