We use a theory of apologies to design a nationwide field experiment involving 1.5 million Uber ridesharing consumers who experienced late rides. Several insights emerge from our field experiment. First, apologies are not a panacea: the efficacy of an apology and whether it may backfire depend...

Improved integration of cycling and transit has the potential to overcome the fundamental limitations of each mode by combining their opposite strengths of flexibility and action radius. The benefits of such integration potentially extend beyond user benefits and the trip level. We present seven...

In countries, such as Singapore, that have implemented vehicle congestion policies, recent years have seen a shift towards motor vehicle taxes based on car use. Ownership taxes reduce the number of cars on the road, leaving the price per trip largely unaffected. Use taxes such as fuel taxes and...

This paper proposes a framework to monitor progress towards improved integration in public transport. The framework adapts some elements of Transport Sustainability Barometer (TSB) which is a tool to assess transport sustainability in Swedish cities. The suggested indicator set follows the...

This paper explores the role of modern trams in Chinese cities and identifies issues and challenges of integrating modern trams with other public transport modes. The Suzhou National High-tech District (SND) Tram is chosen as a representative case for study. The findings show that, due to the...

Local governments spend roughly $1.6 trillion per year to provide a variety of public services ranging from police and fire protection to public schools and public transit. However, we know little about public sector's productivity in delivering key services. To understand the productivity both...

Public transit accounts for only 1% of U.S. passenger miles traveled but nevertheless attracts strong public support. Using a simple choice model, we predict that transit riders are likely to be individuals who commute along routes with the most severe roadway delays. These individuals' choices...

We propose a theory-inspired measure of the accessibility of a city's center: the size of the surrounding area from which it can be reached within a specific time. Using publicly available optimal-routing software, we compute these "accessibility zones" for the 109 largest US and European...

Designing public transport networks involves tradeoffs between extensive geographic coverage, frequent service on each route, and relying on interconnections as opposed to direct service. These choices, in turn, depend on individual preferences for waiting times, travel times, and transfers. We...
