Eight Months of Data Now Available on One-Stop Interactive Highway Hot Spots & Volumes Tracker
SANDAG has officially unveiled a new interactive data map that tracks travel patterns on local highways amid the pandemic. Since the statewide stay home order was put in place, SANDAG has continued to monitor the effects of COVID-19 on the economy and travel in the San Diego region.
The new SANDAG Highway Hot Spots & Volumes Tracker Highway Hot Spots & Volumes Trackeris a one-stop data source that tracks weekday month-by-month vehicle miles traveled on local highways, including traffic speeds and average daily traffic volumes. The data available on the tracker includes March through October 2020, and users can also compare current data to the same time in 2019. The SANDAG tracker will be updated monthly.
“This new tool is intended to be a resource to assist community members and local leaders with current traffic data to make regional decisions,” said SANDAG Director of Research and Program Management Dr. Cynthia Burke. “The Highway Hot Spots & Volume Tracker Highway Hot Spots & Volumes Trackerhas shown us that the greatest drop in traffic volumes this year were seen in April when we were down 44%, compared to the same time last year.”
The SANDAG tracker also shows that between June and October, traffic volumes hovered between 15% and 16%. The number of vehicle miles traveled on our eight local highways reflected this pattern. Data shows that in October, traffic remained lowest on SR 163, which was down 29%, compared to October 2019, and that SR 78 and I-805 were the closest to last year’s figures at this time (down 11% and 13%, respectively).
The SANDAG Highway Hot Spots & Volumes Tracker offers multiple ways to interact with and explore the data, such as filtering to focus on points of interest and selecting data points in the chart to make simultaneous comparisons.
