In addition, we collect data on approximately 50 of the higher volume roadways and streets in anticipated growth areas annually, while another 170 sites are scheduled to be counted every other year. This allows us to keep our finger on the pulse of growth and change in our community. All of the MDOT count sites are scheduled in accordance with MDOT’s triennial schedule. 85% of which, are at MDOT designated count locations. We collect travel data at sites along major roadways and other routes in support of the regional planning process, as well as to fill a jurisdiction’s particular need. In 1998, GRPC entered into an agreement with MDOT, whereby GRPC began collecting all of MDOT’s scheduled volume counts within the three county region.įollowing a detailed schedule, the program staff “Road Warriors” collect traffic data at approximately 1,300 sites.
