• Abstract:
  Using the inspection summary data (24-1 reports) from SHA for years 2006 to 2010 and inspection and violation ; files of Motor Carrier Management Information System (MCMIS) for the same years, the Maryland State Police ; (MSP) and Maryland Transportation Authority Police (MdTAP) roadside inspections were evaluated. The ; comparison with peer states and the national trend found that the roadside inspections of Maryland are effective. ; Specifically, Maryland conducted more inspections than many other states in terms of the absolute number of ; inspections and the number of inspections normalized by population and VMT. In addition, reduction in violations in ; Maryland was noticeable during these study years, a larger drop than the national average. This trend analysis ; suggests that population of safe trucks in Maryland has been increasing gradually, at rates higher than the national ; averages. This population of safe trucks may be the result of the effectiveness of prior inspection programs in the ; state and nationally. The Integer Programming resource allocation model successfully reallocated existing resources ; in a way to maximize benefits from avoided crashes. The modeling findings suggest that the current level of ; inspections, i.e. without resource reallocation, are quite effective and generate significant benefits to Maryland ; citizens. With resource reallocation, the benefits would increase significantly. Depending on scenarios, the ; percentage increase of additional benefits gained by resource reallocation ranges between 14.58% and 28.18% for ; the MSP roadside inspection program, and between 9.01% and 22.62% for the MdTAP roadside inspection program. ; A budget increase scenario was also considered. A budget increase of 10% using current inspection capacity, and ; assuming a 40% crash reduction coefficient, would result in MSP and MdTAP increasing benefits by 2.22% and ; 7.23% respectively. At the disaggregated level, the model recommends TWIS to conduct more level I and level II ; inspections, and fewer level III inspections. On the other hand, for MdTAP and MSP Roving County, an increase in ; level III inspections would have a significant impact on capturing potentially dangerous drivers who avoid fixed ; inspection locations on purpose.
