PennDOT Field Devices - State - Commercial Vehicle Check Equipment Functionality
Subsystem Description
'Commercial Vehicle Check Equipment' supports automated vehicle identification at mainline speeds for credential checking, roadside safety inspections, and weigh–in–motion using two–way data exchange. These capabilities include providing warnings to the commercial vehicle drivers, their fleet managers, and proper authorities of any safety problems that have been identified, accessing and examining historical safety data, and automatically deciding whether to allow the vehicle to pass or require it to stop with operator manual override. Commercial Vehicle Check Equipment also provides supplemental inspection services such as expedited brake inspections, the use of operator hand–held devices, mobile screening sites, on–board safety database access, and the enrollment of vehicles and carriers in the electronic clearance program.
Functional Object: CVCE Citation and Accident Electronic Recording
'CVCE Citation and Accident Electronic Recording' documents accidents, citations, and violations identified during roadside safety inspections and forwards the information to the Commercial Vehicle Administration Center for processing. It collects data from the vehicle to help characterize the circumstances surrounding the accident.
Functional Object: CVCE Electronic Screening
'CVCE Electronic Screening' supports electronic credentials and safety screening of commercial vehicles at mainline speeds. It processes the data from the commercial vehicles along with accessed database information to determine whether a pull–in message is needed. It may also generate random pull–in messages with provisions for facility operators and enforcement officials to have manual override capabilities.
Functional Object: CVCE Safety and Security Inspection
'CVCE Safety and Security Inspection' supports the roadside safety inspection process, including wireless roadside inspections that are conducted remotely. It reads on–board safety data at mainline speeds to rapidly check the vehicle and driver and accesses historical and current safety data after identifying vehicles at mainline speeds or while stopped at the roadside. The capabilities to process safety data and issue pull–in messages or provide warnings to the driver, carrier, and enforcement agencies are also provided. It includes hand held or automatic devices to rapidly inspect the vehicle and driver, including driver logs. Results of screening and summary safety inspection data are stored and maintained.
Since a vehicle may cross jurisdictional boundaries during a trip, it supports the concept of a last clearance event record carried on the vehicle tag. The last clearance event record reflects the results of the roadside verification action. For example, if the vehicle is pulled over in State A and undergoes credential, weight, and safety checks, the results of the clearance process are written to the vehicle s tag. If the vehicle continues the trip and passes a roadside station in State B, the State B station has access to the results of the previous pull–in because it can read the last clearance event record written by the State A roadside station. It associates high–risk cargo with the container/chassis, manifest, carrier, vehicle and driver transporting it.
