ODOT employees can go to Transportation Data Management System to access the internal portal. This is limited to data years that have been finalized. The public can go to Transportation Data Management System to access the public portal. The OTMS pages are optimized for use in a Chrome browser. At most sites, it also allows you to access more detailed count data. The available data includes common annual statistics, such as Annual Average Daily Traffic (AADT) and truck percentages. Or if you know a Location ID already you can look it up that way using the Search box. You can zoom in, zoom out, and pan to an area of interest. Traffic count information assists in identifying new economic development areas, assists in selecting appropriate roadways designs during construction projects, can inform planners where new or expanded facilities are needed on existing roadways, alerts planners of growth trends, etc.The Oregon Traffic Monitoring System (OTMS) is an online interactive tool where you can access count data. Although open and available to the general public, the most common users of the database include local city and county planners, engineers and developers. The traffic count data collected is uploaded into a searchable database.

The AADTs for traffic count sites are rounded using the following convention: Volume

Occasionally, at the request of local jurisdictions and other special circumstances, speed counts are taken, providing various reports on vehicular speed, time of day, etc.В Vehicle classification counts have also been taken, wherein the traffic volume is reported in various formats by the type of vehicle (cars, buses, various sized trucks, etc.). The data is then downloaded and processed using specially designed software.В Factors developed and provided by MDOT (axle factors, monthly factors and annual increase factors) are then applied to the raw count data to derive the Annualized Average Daily Traffic (AADT) count for each location. In addition to the regularly schedule traffic counts, numerous other special counts will be taken to support specific transportation planning projects, or at the request of local governments for various reasons.ДЄll traffic counts conducted by GRPC meet MDOT and Federal Highway Administration criteria for data collection activities.В They are taken using automated tube counters for a period of not less than 48 hours. 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.В 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 MDOTвЂ™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 jurisdictionвЂ™s particular need.В In 1998, GRPC entered into an agreement with MDOT, whereby GRPC began collecting all of MDOTвЂ™s scheduled volume counts within the three county region.ДЇollowing a detailed schedule, the program staff вЂњRoad WarriorsвЂќ collect traffic data at approximately 1,300 sites. GRPCвЂ™s Transportation Planning Division has been conducting its traffic volume data collection (traffic counts) program in Hancock, Harrison and Jackson counties for over thirty years.
