The Mississippi Highway System consists of about 75,000 miles of public roads and streets. Of them, about 11,000 miles are maintained by MDOT, and the rest are maintained by county, city, and other agencies. The total road mileage increases constantly with the addition of new subdivisons and connector roads. Also, highway improvement projects may take place on the state, regional, and local levels every year according to the maintenance needs and traffic growth needs of these transportation agencies, which will change the road inventory and condition as well as the mileages associated with the pavement conditions. It is MDOT’s responsibility to gather the latest road mileage and pavement status information of the entire public road system in Mississippi annually and report it to the Federal Highway Administration (FHWA).
For the state maintained highway network and part of the National Highway System, the mileage, pavement type, and location information is well stored and updated in a timely manner. Therefore, this inventory data collection study is mainly focused on the remaining 64,000 miles non-state maintained public roads. Currently, field travel is used by the Planning Division of MDOT to collect the inventory data of non-state maintained public roads. An inventory crew continuously rides every road in the state, one county at a time, and brings detailed information to update the database/GIS maintained by the Planning Division of MDOT. It is known that the field travel approach for inventory data collection is time-consuming and costly. The Planning Division of MDOT needs a more economical and efficient way to collect location, surface type, and road length for the public road system. This research project will use an online survey distributed to all other states in the country to identify the state of the practice strategies used by other states and based on the research results make recommendations to MDOT. The research will also find a possible solution to the Mississippi problem using a pilot study.
