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.
Changing how people travel and how freight is moved to more environmentally friendly modes of transport, such as non-motorized transport, mass transit, and car sharing, can reduce overall fuel use and emissions per capita.
- Non-Motorized Transport - Pedestrian transport is an efficient way to use road space and thus reduces vehicle congestion on roadways, supports the local economy, enhances access to jobs, education and services for the poor, improves health through exercise, and boosts social cohesion. Bicycle travel is historically a common form of transport in many countries. This prevalence is giving way to motorized transport as car ownership expands and more street space is allocated for motorized transport. Bicycle programs ensure allocation of street space for bicycles, safety enhancements, interconnection with other transport modes, and many of the benefits associated with increased pedestrian transport.
- Mass Transit - Bus transit systems are the most common form of mass transit, proving viable in urban and rural areas, and so play a fundamental role in meeting both basic transport demands and low emissions transport objectives by connecting with all forms of transit - motorized & non-motorized. Train or rail-based transit systems can be the most efficient form of passenger transport if population density is sufficiently high. Rail transport for freight can also be more time- and cost-efficient than road-based freight transit. Bus Rapid Transit (BRT) systems share similar advantages to passenger train systems by employing high-occupancy buses for high density areas along dedicated routes and stations, however at a lower infrastructure and operational cost.
- Carpooling - Sharing rides in private vehicles for daily commuting and errands reduces per capita emissions. Strategies to incentivize ridesharing include: high-occupancy vehicle (HOV) lanes, road pricing, parking discounts, website forums and applications for smart phones.
