104.33 Flexible Automated Speed Enforcement
CATEGORY 100 PRELIMINARY SECTION 104.33 — FLEXIBLE AUTOMATED SPEED ENFORCEMENT
104.33.01 Description
Flexible Automated Speed Enforcement (ASE) deployments are used when work activity is 60 days or less and may include different ASE deployment locations for each work shift. Projects using flexible ASE generally require set up and removal of maintenance of traffic items at the start and end of each shift. Example projects include resurfacing, restoration and rehabilitation projects, maintenance projects, etc. Coordinate with the Administration and its Automated Speed Enforcement Contractor for ASE in the work zone. Provide work zone signage, workers present trailer(s), speed display trailer(s), and protection devices to accommodate ASE in the work zone. Contact the Office of Traffic and Safety Traffic Development and Support Division (OOTS TDSD) ASE program representative (410-787-5860) at least two weeks prior to fabricating and installing ASE signs to determine exact locations for the ASE unit(s), ASE signs, workers present trailer(s), and speed display trailer(s).

Coordinate and cooperate with the Project Engineer and the ASE program representative to implement the ASE system on this project throughout construction. The ASE program representative is located in the Office of Traffic and Safety, Traffic Development and Support Division. Obtain approval from the ASE program representative for the ASE unit location(s), protection vehicle location(s), ASE sign locations and sizes, workers present trailer locations(s), and speed display trailer location(s). At least two weeks prior to the start of the project, arrange a field meeting with the Project Engineer and the ASE program representative to jointly identify locations for the ASE unit(s), the protection vehicle dedicated to ASE, the workers present trailer(s), and the speed display trailer(s). During the project, contact the Project Engineer and the ASE program representative a minimum of 48 hours prior to any changes not approved during the initial field meeting or due to unforeseen changes. Contact the Project Engineer and the ASE program representative a minimum of four hours before any work cancellations. Inform the Administration within 30 minutes of starting and ending work the exact start time(s) and exact end time(s) when workers are present in the work zone.
