Data Division

Traffic Scene 

The Data Division provides a foundation for roadway enhancement, intersection design, traffic calming, trail improvements, safety analysis, transportation plans, vision zero efforts, and traffic signal timing.  Our goal is to provide essential information impoving the traveling environment within the Municipality. Information can be found online at: http://traffic.muni.org/

Collection and Processing

Using several different methods, the Data team conducts studies of traffic characteristics, collects related data, and interprets crash information provided by various law enforcement agencies.

Shown here is just one of the many devices for obtaining traffic data.

 

Types of Collected Traffic Data:

  • Roadway Volumes (Vehicular, Pedestrian, and Bicycle)
  • Pathway and Trail Volumes
  • Vehicle Speed Studies
  • Traffic Gap Studies
  • Travel Time Delay
  • Vehicle Classification
  • Other studies (circulation, cut through, travel behavior, license plate, etc.)
  • Intersection Safety Analysis
  • Crash Information (APD, UAA, Aiport Police, Whittier Police, State Troopers, etc.) 
  • Other traffic related information

Analysis and Traffic System

Essentials like: volumes, studies, crashes, traffic control and roadway characteristics (directional flow, intersection geometry, approach lanes, road class, etc.) are compiled, edited and loaded into the Traffic Data Management System.

Data is then geographically related and applicable information is added to the system such as: average annual daily traffic figures, roadway classifications, appropriate federal/state safety factors, collision diagrams, equations, and any other necessary features.

Loaded information is analyzed and subjected to various quality assurance measures prior to creation/release of any traffic statistics.

This publically accessible system is maintained by the Data Division.

Publication

Annual traffic data is compiled and statistical analysis is performed for all information gathered along roadways, parthways, or trails within the Municipality of Anchorage. The Data Division ​uses this information to create and publish the Annual Traffic Report.

Information contained within the report is used to evaluate and determine proper techniques for meeting transportation needs within the municipality such as: traffic safety improvements, transportation planning, and optimal signal operations.  The information can also be used to determine locations where redesign could possibly decrease the number of traffic crashes.
