This tab has the fields related to Commercial Vehicle Restrictions (CVR). Commercial vehicle restrictions are composed of directives to the routing engine that guides the behavior and attributes of commercial vehicles making trips along the route. Depending upon vehicle attributes provided (such as height, width, length, weight) and the commercial vehicle restriction attributes present in the road network, decision is made whether to allow to route a particular vehicle over a segment or not. If there is no commercial vehicle restriction attribute present in road network, input restriction parameters will have no effect in the resultant route.

Following are the set of preferences for commercial vehicle restrictions:

Preference Description
Use vehicle restriction

Specifies whether a CVR priority is to be used while determining the route.

Select this option if you are defining a CVR.

Loosening barrier restrictions

Specifies whether barriers are to be removed while determining the route. These restrictions are most often encountered when a commercial vehicle is prohibited from traversing a segment due to local ordinance or a commercial vehicle is allowed on the segment but only when it must (for example, last mile access or local delivery). Routes where a barrier has been removed will still have a higher route cost even if the route is shorter or faster than a route with no barrier.

Select this option if you are loosening restrictions.

Type of vehicle

Specifies the type of vehicle to be restricted based on the height, weight, length, or width while determining the route. Commercial vehicles are divided into different types ranging from short trailers to long triples. The Commercial Vehicle Restrictions attribution is organized on a per-vehicle type basis. This means it is entirely possible for a segment to be preferred for one vehicle type and the same segment have a restriction for another type of vehicle.

Choose either all or one of these types of vehicles:

  • Intermediate double
  • Long double
  • Other long combination vehicle
  • Semi trailer
  • Standard double
  • Straight
  • Triple
Length Specifies the maximum length of a vehicle. Any vehicles over this value will be restricted when determining the route.
Height Specifies the maximum height of a vehicle. Any vehicles over this value will be restricted when determining the route.
Width Specifies the maximum width of a vehicle. Any vehicles over this value will be restricted when determining the route.
Linear unit

The unit to be used for specifying the maximum length, height, and width of the vehicle:

  • Feet (default)
  • Meters
  • Yards
Weight Specifies the maximum weight of a vehicle. Any vehicles over this value will be restricted when determining the route.
Weight unit

The unit to be used for specifying the maximum weight of the vehicle:

  • Kilogram
  • Metric Tonnes
  • Pound (default)
  • Ton
