IDOT Weigh Stations

Status: Existing

Description

IDOT fixed site weigh scales. Pre–Pass Systems being installed at all interstate weigh stations. The weigh stations are physically maintained by IDOT, but are staffed by the Illinois State Police. This includes equipment such as high–speed weigh in motion equipment and pre–clearance / truck credentialing equipment.

Functional ObjectDescriptionUser Defined
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.False
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.False
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.
False
CVCE Weigh–In–Motion'CVCE Weigh–In–Motion' measures and records axle weights and gross vehicle weight without requiring the vehicle to come to a stop. Both permanent and portable installations are supported and may be performed in conjunction with electronic clearance or as a separate application.False

Physical Standards

Document NumberTitleDescription
CTI 4001Roadside Unit (RSU) StandardThis document establishes a non–proprietary, communications–agnostic, industry consensus Roadside Unit (RSU) Standard. An RSU is a transportation infrastructure communications device that is a part of a Cooperative Intelligent Transportation Systems (C–ITS) transportation environment. The goal of such an environment is to reduce the number of fatalities and injuries on roadways, improve mobility, and reduce environmental impacts of transportation systems. Commonly known as the Connected Vehicle (CV) environment in the United States (US), it includes both connected human–driven vehicles and connected automated vehicles (CAVs). The terms Vehicle–to–Infrastructure (V2I) and Vehicle–to–Vehicle (V2V) are used to reflect the exchanges of messages within the CV environment. The vision for this technology has expanded to include all types of travelers including pedestrians, cyclists, multimodal travelers, and other vulnerable road users (VRUs), and is referred to as Vehicle–to–Everything (V2X) technology and V2X communications.
