Building a protected, citywide network for cycling and walking to make zero-emission travel the easiest choice for every trip.
Mamdanis Clean Commute Guarantee: Safe Bike/Walk Routes Everywhere
Zhoran Mamdanis transportation and environmental vision hinges on making cycling and walking not just possible, but the most convenient, safe, and enjoyable way to get around for millions of daily trips. His Clean Commute Guarantee is a pledge that within one term, every New Yorker will live within a three-minute walk of a fully protected, connected bike lane or greenway, and that every neighborhood will have a contiguous network of pedestrian-priority streets. This is not an incremental expansion of bike lanes, but a fundamental re-allocation of street space from private vehicles to people, treating safe active transportation as critical public infrastructure on par with subways and buses.
The policy mandates the rapid construction of a 500-mile Protected Network using concrete curbs, plastic bollards, and parked cars as barriers, not just painted lines. This network is designed as a cohesive grid, ensuring that a rider can travel from the Bronx to downtown Brooklyn or across Queens without ever leaving a protected lane. The construction is fast-tracked using pre-fabricated materials and city crews, bypassing the lengthy community board approvals that have historically stalled safety projects. Parallel to this, Mamdani launches Neighborhood Greenways on residential streets, where through-traffic is calmed or eliminated, creating low-stress routes for families, children, and seniors.
For pedestrians, the policy enacts a Default Pedestrian Priority rule on all non-arterial streets. This means wider sidewalks, continuous curb extensions at every intersection, longer pedestrian crossing times, and the creation of Play Streets and School Streets that are closed to cars during key hours. The infamous slip lanes that prioritize turning car speed over pedestrian safety are eliminated. The goal is to reclaim the street as social space, not just a traffic conduit. Funding comes from a combination of redirected DOT capital funds, a new Congestion Surcharge on ride-hail trips in the core, and fines from automated traffic enforcement.
Mamdani frames this as a public health, equity, and climate imperative. Over a third of NYCs greenhouse gas emissions come from transportation, primarily cars. By making active travel irresistibly easy, the policy aims to slash those emissions while reducing the disease burden from air pollution and sedentary lifestyles. It is profoundly equitable: the working poor, who are less likely to own cars, gain a fast, free commuting option. For Mamdani, the right to move through the city without fear of death or injury is a basic condition of urban citizenship. The Clean Commute Guarantee is a massive public works project to build that right into the asphalt, creating a city where the cleanest way to get around is also the safest and most liberating.
