Avoid, Shift, Improve Framework

The avoid, shift, improve (ASI) framework enables development stakeholders to holistically design low-emission transport strategies by assessing opportunities to avoid the need for travel, shift to less carbon-intensive modes, and improve on conventional technologies, infrastructure, and policies.

Avoid Trips and Reduce Travel Demand
Shift to Lower-Emission Transport Modes
Improve Technologies

Under the ASI framework, the conventional interpretation of transportation technology is broadened beyond traditional improvements to vehicles and fuels. Improvements made to technologies under this framework include the: vehicle level, system level, and institutional level.

  • Vehicle Level - Low-emission vehicle technology improvements cover conventional petroleum-based systems (such as hybrid-electric and dual-fuel vehicles); non-petroleum fuel vehicles (such as natural gas, hydrogen fuel cell, and battery electric vehicles); and vehicle component improvements (such as start-stop devices, idle reduction devices, and regenerative braking systems). Low-emission fuel technology improvements include low-sulfur conventional petroleum fuels; alternative fuels (such as ethanol, biodiesel, natural gas, and propane; hydrogen fuel-cell systems; and electric rechargeable battery systems.
  • System Level - Low-emission infrastructure technology improvements include reserving or reclaiming space for non-motorized transport modes (such as pedestrian and bicycle routes, bicycle sharing, etc.) and mass transit modes (such as BRT, bus, train, ferry, etc.), as well as park and ride networks, vehicle parking distribution, car sharing networks, and real-time parking/traffic information systems. Low-emission urban planning improvement examples include zoning for mixed-use and denser development along multimodal transport routes, and transit-oriented development.
  • Institutional Level - Low-emission improvements to policies include integrating land-use planning and zoning with transport planning and development; economic and fiscal instruments (such as fuel/private vehicle taxation, congestion pricing, parking tariffs, low-emission vehicle tax incentives, alternative fuel production subsidies, etc.); and public awareness campaigns. Low-emission technology improvements using tools and software cover development scenario modeling (e.g. Land Use-Transport Integration - LUTI - models), mobile device applications (mass transit, road, and parking system real-time status tools, and car sharing tools), and website forums to organize and publicize non-motorized transport commuter options and events.
