Subsidies to Relieve Urban Traffic Congestion

Key Points

The aim is to explore whether subsidies for public transport can help manage urban traffic congestion more effectively.
Analysis of congestion charge effects on traffic patterns
Evaluation of public transport subsidy models
Comparison of bus fare structures by time of day
Subsidies to public transport can partially compensate for the absence of congestion charges
Bus subsidies are deemed most suitable for London and major US cities
Implementing variable bus fares based on peak and off-peak hours can enhance efficiency

Abstract

Subsidies to public transport may to some extent offset the failure to levy congestion charges on cars. This paper sets out the relevant criteria and concludes that bus subsidies would be appropriate in London, and probably in large US cities. Fares should vary according to time of day.
