Dept. of Civil and Environmental EngineeringAmerican Transportation Research InstituteUS Transportation CollectionThis project investigated the use of large streams of truck GPS data available from the American TransportationResearch Institute (ATRI) for the following statewide freight modeling and planning applications in Florida:(1) Average truck speed data were developed for each (and every) mile of Florida\ue2\u20ac\u2122s Strategic Intermodal System(SIS) highway network for different time periods in the day.(2) Algorithms were developed to convert raw truck GPS data into a database of truck trips. The algorithms wereapplied to convert four months of raw data, comprising 145 million GPS records, into more than 1.2 milliontruck trips traveling within, into, and out of Florida.(3) The truck trip database developed from ATRI\ue2\u20ac\u2122s truck GPS data was used to analyze truck travelcharacteristics, including trip duration, trip length, trip speed, and time-of-day profiles, for different regionsin the state. Further, distributions of origin-destination (OD) truck travel times were derived for more than1,200 OD pairs in the Florida Statewide Model (FLSWM).(4) ATRI\ue2\u20ac\u2122s truck GPS data were evaluated for their coverage of truck traffic flows in Florida. At an aggregatelevel, the data were found to capture 10 percent of heavy truck volumes observed in Florida.(5) The data were used to develop OD tables of statewide freight truck flows within, into, and out of Florida. Todo so, the truck trip database developed from ATRI\ue2\u20ac\u2122s truck GPS data was combined with observed trucktraffic volumes at different locations in Florida and other states using OD matrix estimation procedures. TheOD tables were developed for the spatial resolution of traffic analysis zones used in FLSWM.(6) Preliminary explorations were conducted with ATRI\ue2\u20ac\u2122s truck GPS data for analyzing truck travel routesbetween different locations and for analyzing truck flows out of seaports
