Maryland Motor Carrier Program Safety Assurance Evaluation

摘要

The State of Maryland is implementing the Commercial Vehicle Information Systemsand Network (CVISN) architecture to enhance and support Commercial Vehicle Operations (CVO) administrative processes, improve roadside safety inspection operations, and implement electronic screening for commercial vehicles. The proposed study evaluates the safety assurance activities of Maryland's Roadside Enforcement Program due to the current implementation of CVISN-related computer and communications systems used to collect and distribute safety-related data. The safety-related activities mainly include the commercial vehicle and driver inspections at roadside weigh/inspection facilities and by roving crews in Maryland, and the collection and distribution of inspections. This study involves the following safety-related activities: Electronic collection of inspection data at roadside inspection facilities; Transmission of inspection data from roadside inspection facilities; Distribution of safety information to computers at the roadside. The following criteria are evaluated for both electronic and manual inspections: throughput of commercial vehicles being inspected; efficiency and effectiveness of commercial vehicle and driver inspections in Maryland; availability of safety inspection data in a timely manner; driver and inspector satisfaction with the inspection process; completeness and accuracy of inspection reports; and the efficiency of uploading inspection data.
