Information, Pricing , and Permits for Externality Management in Multimodal Urban Transpor t
"Urban transport creates problems that go beyond individ ual journeys: traffic congestion wastes time, vehicle emissions harm the environment and health, and crowded public transport can impose c osts on others. My research investigates how cities can reduce these problems by influencing the choices people make about how, when, and where to travel.
"I focus on three approaches: providing travel lers with better information, using prices such as road tolls, and in troducing tradable permits to manage transport demand. Drawing on eco nomic models and real-world navigation data, I examine how people res pond to these policies and how their decisions affect congestion, emi ssions, exposure to pollution, and social welfare.
"A central q uestion is why a policy that benefits one group or transport mode may sometimes create problems elsewhere. The goal is to support more eff ective and sustainable urban transport policies.
"The main find ing is that there is no single solution to urban transport problems. Giving people better information can help them avoid congestion and m ay reduce emissions, but it does not always benefit everyone. For exa mple, encouraging drivers to take the metro can ease road congestion while making trains more crowded.
"I also show that pollution f rom cars can discourage cycling, potentially keeping cities in a patt ern of heavy car use. Data from a navigation app in Beijing suggest t hat traffic alerts are associated with shorter journeys and less expo sure to congestion.
"Finally, transport charges and tradable pe rmits can both help manage travel demand, but their effectiveness dep ends on uncertainty and how flexibly policies can respond. The key le sson is that transport policies must consider how people react and ho w different travel modes affect one another."

DESCRIPTION: Information, Pricing, and Permits for Externality Managem ent in Multimodal Urban Transport "Urban transport creates problems t hat go beyond individual journeys: traffic congestion wastes time, ve hicle emissions harm the environment and health, and crowded public t ransport can impose costs on others.

Drawing on economic models and real-world navigation data, I examine how people respond to these policies and how their decisions affect c ongestion, emissions, exposure to pollution, and social welfare."A ce ntral question is why a policy that benefits one group or transport m ode may sometimes create problems elsewhere.

Giving people better information can help them avoid congestion and m ay reduce emissions, but it does not always benefit everyone.
