Initiative 20: Engine-Related Restrictions

Engine-Related Restrictions
Description: A special case of vehicle restriction granting access to a target area only for vehicles that meet a certain level of environmental standard. These strategies try to reduce the environmental externalities of freight traffic by fostering the use of environmentally friendly technologies.
Targeted mode: All traffic Geographic scope: Area
Type of initiative: Traffic management: environmental/vehicle restrictions Primary objective: Reduce pollution
Expected costs and level of effort to implement: Engine-related restrictions require careful planning that should include stakeholder engagement, a full assessment of possible outcomes, and an analysis of the initiative’s objectives. For efficient implementation, additional strategies may be required (e.g., dedicated loading/unloading zones, UCCs).
Advantages:

  • Environmental sustainability
  • When combined with eco-loading zones:
    • May increase efficiency
    • May decrease operational costs
Disadvantages:

  • High probability for unintended consequences:
    • Increase operational costs
  • Require carriers to upgrade their fleets
  • Hard to enforce
Examples:

  • European cities: Copenhagen, Denmark; Amsterdam, The Netherlands; Berlin, Germany; and London, England (Quak 2008; PARFUM 2009; LEEZEN 2010)
  • Combined Engine Relate Restrictions with Eco-Loading Zones: Bremen, Germany (LEEZEN 2010)
  • Clean Truck Program Ports of Los Angeles/Long Beach, California, United States (Port of Los Angeles 2013a)
