The Jackson MPO works cooperatively with the Mississippi Department of Transportation (MDOT) to collect traffic count data for all state and non-state maintained roadways that are part of the functional class system in the Jackson Urbanized Area (JUA). The collected traffic count data is used by the MPO in the development of a number of transportation planning activities including the Long Range Transportation Plan (LRTP), Congestion Management Process and Pavement Management System.
The traffic count viewer, link at bottom of this page, provides traffic count data collected by the MDOT and the Jackson MPO. Traffic count data for the JUA is collected on a three (3) year cyclical basis in Hinds, Madison and Rankin Counties. Every third year the data collection process occurs in one of the aforementioned counties. Due to each county being counted every third year estimates are developed for the interim years in which traffic count data is not collected for a particular traffic segment in the corresponding county.
Traffic count data shown in the viewer are Annual Average Daily Traffic (AADT) counts. This means that the raw data is collected over a 48 hour period and traffic adjustment factors are applied to that data to arrive at an “annual” average daily traffic count total. The factors used are provided to the MPO and developed by the MDOT. Average Daily Traffic (ADT) count data is a snapshot of the actual day, week and month the data was collected. AADT applies the factors developed by MDOT that takes into consideration high and low seasonal and daily traffic patterns to arrive at a more representative “annual” traffic count for the selected roadway segment.
