Planning for Truck Routes and Other Related Considerations 9 mobility, access, and circulation. Design considerations include lane width, turning radii, median island radii, vertical clearance, and location of fixed objects (e.g., signs, utility and signal poles, street trees, other roadside features)

10 Design and Access Management Guidelines for Truck Routes: Planning and Design Guide agencies have established statewide or local freight advisory groups that meet regularly (e.g., bi-monthly, quarterly) to discuss safety, operational, and design issues for accommodating trucks on the roadway system.

12 Design and Access Management Guidelines for Truck Routes: Planning and Design Guide shopping centers' frontages face the street for easy access to shoppers, delivery trucks mainly access the backs of stores for deliveries. The separate access facilities for trucks should avoid pedestrian and vehicle conflicts.

14 Design and Access Management Guidelines for Truck Routes: Planning and Design Guide of truck routes is a key operational and planning activity that should consider the truck demand volumes, the origins and destinations of truck shipments, and the suitability of particular roads and corridors to accommodate trucks of specific sizes. When designating a truck route that is not already an arterial, it is also important that such routes not split neighborhoods in urban areas.

Planning for Truck Routes and Other Related Considerations 15 • No state shall prohibit tractor-semitrailer-trailer combinations. • No state shall prohibit the operation of semitrailers or trailers that are 28.5 ft long when operating in a tractor-semitrailer-trailer combination if such trailer or semitrailer was in actual and lawful operation on December 1, 1982, and such combination had an overall length not exceeding 65 ft.

18 Design and Access Management Guidelines for Truck Routes: Planning and Design Guide Colorado publishes maps showing designated routes that must be used by trucks hauling nuclear or other hazardous materials. Trucks loaded with hazardous materials subject to the Colorado routing regulations must use the designated routes.

20 Design and Access Management Guidelines for Truck Routes: Planning and Design Guide intrastate commerce as well. In many states, federal agencies have delegated their enforcement of federal regulations within that state to a state law enforcement agency, such as the state police or highway patrol.

22 Design and Access Management Guidelines for Truck Routes: Planning and Design Guide 3.4.1 Encroachment on Shoulders or Roadside Areas Damage to areas outside the traveled way as a result of encroachment by turning trucks is a key maintenance concern for transportation agencies. Some access management techniques require turning maneuvers.

24 Design and Access Management Guidelines for Truck Routes: Planning and Design Guide The driveway permitting process not only establishes the number of driveways a property may have, but it also influences driveway locations. Driveway permits often include conditions, such as provision of turn lanes, wide turning radii, and so forth.

26 Design and Access Management Guidelines for Truck Routes: Planning and Design Guide discontinuities in routes likely to be used by future OSOW permit operations. As part of the planning process, route continuity and available alternative routes should be analyzed, and routes likely to be used by future OSOW permit operations should be preserved with respect to the following: • Vertical and horizontal clearance limitations at structures.

28 Design and Access Management Guidelines for Truck Routes: Planning and Design Guide 3.7.3 Truck Parking Places for Driver Rest There is a nationwide shortage of truck parking places for driver rest. Over-the-road truck drivers are required to take 10 hours off duty following no more than 14 consecutive hours on duty or a cumulative total of 11 hours of driving time during that 14-hour period (49 CFR 395)
