WebFor over 10 years, PeMS has collected data on traffic volumes and speeds on California’s freeways from a network of individual traffic detectors. Using this historical data, MTC calculates an annual time series for congested VMT in the Bay Area. The share of weekday VMT in congestion is the average daily share of congested VMT on Tuesdays ... WebBefore we input vehicle volumes, we need to first define our time intervals. Since we collected 5-min loop detector data from PeMS, each interval is 300 seconds. For every hour there are 12 intervals of 300 seconds therefore 3 hours of data is 36 intervals. Select Base Data > Time Intervals in the toolbar.
