Illinois Department of Transportation and Illinois State Police

Joint Operational Policy Statement
Annex G: Traffic Systems Management

Traffic Systems Management: Illinois Department of Transportation (IDOT) and Illinois State Police (ISP) share a mutual role in planning, organizing, implementing and controlling the movements of vehicular traffic using Illinois highways. The spectrum of Traffic Systems Management actions include improved safe vehicle flow, reduced peak period travel, preferential treatment of high occupancy vehicles, parking management, and transit system improvements.

  1. Maintain a close working relationship between agencies to ensure a continuing information flow on the various Traffic Systems Management elements. This requires a regular dialog at operational levels between IDOT and ISP Districts to exchange ideas and suggestions based on field experience. Past expressway projects in Chicago reflect the value of a close working relationship with ample opportunity to communicate. Special techniques must be developed for handling construction-impacted traffic by both the enforcement and highway agencies based on a mutual concern for safe traffic movements.
  2. Mutually develop inter-agency traffic management teams to preplan responses and procedures for handling all major traffic incidents, events and activities.
  3. Plan for accident investigation sites and procedures to reduce impacts of law enforcement reconstruction on traffic flow.
  4. Concentrate on efforts making Illinois Department of Transportation and Illinois State Police personnel "traffic sensitive" to the consequences of their actions in incident management, work zone establishment, vehicle relocation/removal, and truck incident handling. When problems arise, appropriate IDOT personnel should contract the appropriate ISP command officer.
  5. Establish clear communications lines between agencies for mutual notification of accidents and/or incidents.
  6. Provide agency linkages for electronic traffic information exchange by use of computers, television, telephones and other means to assist multi-agency operations as well as public information dissemination.
  7. Meet regularly to establish operational policies, incident management techniques, and plan major highway improvement project impact assessments as well as congestion investigation measures.
  8. Encourage attendance at training seminars, enforcement/engineering conferences and provide other educational opportunities to increase Traffic Systems Management knowledge and provide for engineering and enforcement viewpoint interchange.
  9. Explore all funding opportunities to support enforcement on the highway patrol efforts.

E. Event Planning

Policy: Periodically, events are held on state highways or on WSF ferries by municipalities or other organizations or private entities. It is the policy to allow such events on non-limited access facilities provided that the transportation effects of the event are well publicized and a traffic control strategy is developed by the event organizer and approved in advance.

Roles: WSDOT Headquarters Traffic Operations Office, WSF Operations Center, and Region Traffic Engineers' Offices approve events with coordination with state and local law enforcement, allowing for adequate public communications lead-time. WSP is often asked by even organizers to provide police services during events at the expense of the event organizer.
