Why Public Transit Needs Climate Resilience
Public transit systems—buses, metros, trams, and commuter rail—are the lifeblood of urban mobility. As cities grow, they are also frontline services in the fight against climate change. But extreme weather events pose new challenges: flooded bus depots, overheated rail tracks, disrupted power supplies, and stranded passengers. To maintain reliable, safe, and sustainable operations, public transit must be designed with climate resilience in mind.
Key Climate Risks for Public Transit
- Flooding – Bus depots, underground metros, and rail yards are highly vulnerable.
- Heat Waves – Rail buckling, power supply strain, and passenger comfort issues.
- Storms & High Winds – Damage to shelters, overhead wires, and station infrastructure.
- Snow & Ice – Service disruptions in colder regions, increasing maintenance costs.
- Energy Dependency – Electrified systems may be exposed to grid instability during extreme events.
