TRAFFIC ON REGIONAL ROADWAYS: PERFORMANCE

Approximately 16 million trips are made in the Boston metropolitan region every day. The vast majority of these trips (80 to 85 percent, depending on trip type) involve the use of the roadway network (including trips driving to a transit station and carpools). About 80 million vehicle-miles are logged everyday, over three-quarters of these on the interstate highways and arterial roadways, even though these types of roads account for only a fifth of the centerline miles of the entire roadway network.

Reported here are the results of the data collection effort on the CMS-monitored network of limited-access highways and arterial roadways. Just click on the desired link for the roadway network for more information:

For most of the roadways, travel speed observations were collected during two periods of time. Arterial roadways were monitored in the periods 1995–1999 and 2001–2003. The limited-access highways were monitored in the years 1994–1995 and again in 1999–2000.
