摘要：	Pennsylvania, there are over 72,000 miles of roadways owned by 2,565 municipalities that are not on the Federal-aid system, and are classified as local roads. Currently, the Pennsylvania Department of Transportation (PennDOT) does not have a systematic approach to monitoring the traffic volumes on this portion of the highway system to produce estimates of vehicle-miles traveled (VMT). Federal guidelines such as the Highway Performance Monitoring System (HPMS) Field Manual and Traffic Monitoring Guide (TMG) are of some benefits but provide the most complete and detailed guidance for higher class facilities. This research project aimed to determine a sampling method to collect the data required to produce VMT estimates on local roads owned by municipalities. The proposed research methodology built upon (1) the guidance contained in the TMG and HPMS Field Manual; (2) the experiences of others as discovered through a survey of state DOTs; (3) and an extensive literature search, to develop a plan specific to the circumstances facing PennDOT. It was designed to be feasible within the resources PennDOT has available to devote to local road monitoring, and to provide a foundation of data upon which VMT estimates could be made at the county level for each urban/rural code. The end result was a plan that contained 7,171 count stations spread proportionally over 152 strata. / NOTE:Final rept.
