Please use the link below to download a PDF copy of the OTM Book 7. This book provides details on how to configure traffic control in your work area.
The following management staff have passed their Book 7 training course and may be consulted if you have questions regarding your traffic control configuration.
A few key definitions are below.
Very Short Duration Work
Definition: VSD work occupies a fixed location for 30 minutes or less, but more than 15 minutes including the time it takes to set up and remove traffic control devices. The work site may be moved along the highway and make frequent and short stops where planned work takes place outside of the work vehicle. If a short stop is required at a specific location, it is VSD work rather than a Mobile Operation. If a worker is to be exposed to traffic for more than 30 minutes, including the time required to set up traffic control devices and work time, then a greater protection is required and traffic control layouts for SD work should be used.
Short Duration Work
Definition: SD work refers to activities that require work areas that are continuously occupied by workers and/or equipment for more than 30 minutes but less than one 24-hour period in duration. SD work does not generally include work at a site that extends beyond 24 hours; such work is LD. However, work at the same location may extend over more than one day, and still be considered SD work for the purpose of traffic control device layout, if all of the following conditions are met:
- The approval of the road authority is obtained. The road authority may consider that LD work is more appropriate for recurring lane closures. +NOTE
- Any additional conditions stipulated by the road authority, including working hours, are complied with.
- Continuous work is less than 24 hours.
- The highway (and sidewalk) are restored to the satisfaction of the road authority and returned to normal operation when the daily work shift (or authorized working period) is complete.
