Current System or Situation 17 e Backo ce represents the Backo ce system that rural agencies use to operate and manage the transportation system. Typically, the Backo ce represents the agency's TMS, which may be located at a TMC or may simply be a workstation in a rural agency's o ces.

20 Initiating the Systems Engineering Process for Rural Connected Vehicle Corridors whenever and wherever people travel, agencies can capture in real time what happens between sensors in rural regions, along arterials, and beyond jurisdictional boundaries. Crowdsourcing is benetting transportation operations through improved operations, increased safety and reliability, and cost savings.

Current System or Situation 21 traffic delays, maintain motorist and worker safety, complete roadwork on time, and maintain access for businesses and residents. Work zone management includes collecting and disseminating work zone information to centers that can utilize it as part of their operations, or to Traveler Information Systems (e.g., 511)

Current System or Situation 31 • In states with high freight movement, truck drivers routinely park on interstate ramps and rest stop entrances and exits while commercial parking facility spaces go unused. On rural corridors, fatigued drivers may opt to park on roadway shoulders potentially impacting surrounding tra c safety, or accidentally fall asleep at the wheel potentially crashing into other vehicles or causing a severe incident.
