About this file
This is a technical standard document issued by the Illinois Department of Transportation (IDOT) establishing specifications for traffic control devices. The document, designated as STANDARD 701901-11, was originally issued on January 1, 2013, and has been updated through January 1, 2026. The standards were approved by the Engineer of Design and Environment and the Engineer of Safety Programs and Engineering.
The standard provides detailed dimensional specifications and design requirements for various temporary traffic control devices used in work zones and construction sites. The devices covered include cones, barricades (Type I, II, and III), tubular markers, vertical panels, drums, direction indicators, vertical barricades, detectable pedestrian channelizing barricades, and temporary rumble strips. Specifications are provided in both inches and millimeters, with height measurements taken above the pavement surface. The devices are configured for use at different posted speeds, with distinctions made between daytime-only use and day-or-nighttime applications. The document includes technical drawings showing exact placement dimensions, reflective stripe configurations, and warning light requirements. Recent revisions on January 1, 2026, updated specifications for detectable pedestrian channelizing barricades and temporary rumble strip details.
