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.
