Many cities across the world are implementing strategies that reduce, restrict, or prohibit automobile traffic either directly or indirectly. These include congestion pricing, bus-only lanes, pedestrian streets, green streets, shared spaces, low-emission zones, traffic-restricted zones (ZTL), road diets, bike boulevards, woonerfs, and slow streets.12 Assessing the effectiveness of these strategies is still in its infancy, perhaps due to lack of professional guidance. What is recognized is that past metrics centered on automobiles such as intersection level of service (LOS), and even new metrics such as vehicle-miles of travel (VMT), fail to capture the full range of benefits of these new strategies. |
