COZEEP is not a baseline measure—an important fact when resources are limited and CHP personnel may not be available when requested. Economy will be a factor only as necessary to obtain balance between benefits and resources. Closing highways under construction, maintenance or repair. When roads are closed for construction work or special events, detours often are needed for traffic redirection. If the safe operating speed of traffic through a work zone is significantly less than the approach speed of highway traffic, a reduced work-zone regulatory speed limit may be established. Include these considerations for conditions requiring minor changes in the field: The following guidelines apply to crossover transitions: For temporary modifications of existing ramps, review acceleration and deceleration lanes. Whether additional protection is proposed. Any activity requiring a full roadway closure, Rapid-strength concrete operations, including concrete slab replacement, Roadway excavations that encroach on the traveled way and are not protected by K-rail, Cold planing hot mix asphalt for depths of 2 inches or greater, Asphalt or concrete pavement sealing operations, Placement of reinforcing steel or structural members, Falsework erection or removal, including adjustments. To provide extra maneuvering room, provide wider lanes or additional surfaced shoulder width in transitions and critical alignment. The National Work Zone Safety Information Clearinghouse is a project of the ARTBA Transportation Development Foundation. To order work by the CHP, complete and use Form CEM-2102, “COZEEP/ MAZEEP Task Order.” Before ordering the work, and while preparing the task order, check that: CHP support is appropriate for the type of work to be performed. Whenever possible, allow traffic to have continued full use of the existing facilities. Initiate and obtain CHP sign-off of Form CEM-2101, “COZEEP Daily Report.” At the end of each day, report to the district COZEEP coordinator the COZEEP services used during that week. Verify that no fixed objects (cabinets, poles, and so forth) will reduce the path width at any point. Caltrans attempts to maintain safe and convenient access for pedestrians and bicyclists, who are susceptible to disruptions because of their slower speeds and sensitivity to uneven surfaces, noise, airborne dust, road debris, and fumes.
