Der Schienenverkehr in Deutschland fährt bereits heute zu einem Großteil elektrisch (~90% der Verkehrsleistung auf ~60% elektrifizierten Strecken). Für eine vollständige Defossilisierung sind jedoch auch für die verbliebenen 10% Fahrleistung Lösungen von Nöten. Aufgrund der lokalen...

Gendron-Carrier et al. (2022) studies the effect of subway openings on urban air pollution. The authors find a null average effect, but a negative effect in cities with high initial pollution. In this comment, I perform several robustness checks on the negative effect for high-pollution cities,...

We investigate the impact of light rail projects on the counties they serve through two economic outcomes – growth in employment and wages. In the study, we conduct investigation for relative growth rates in employment and wages in Seattle and Denver metro area counties that are served by...

Workers in developing countries waste significant time commuting, and gaps in public transit constrain access to productive jobs. In many cities, privately-operated minibuses provide 50–100% of urban transit, at the cost of long wait times and poor personal safety for riders. Should...

This paper estimates a global CO2 emissions model using satellite data at 25 km resolution. The model incorporates industrial sources (including power, steel, cement, and refineries), fires, and non-industrial population-related factors associated with household incomes and energy requirements....

In the past few decades the US has seen a large increase in the number of cities offering light rail, heavy rail and commuter rail transit. At the same time, ridership on these rail systems has not increased as fast. Looking at annual ratios of ridership to track mileage for each mode over the...

Urban Rail Transit Passenger Flow Modeling (URTPFM) is the foundation of urban rail transit (URT) planning, design, and operation. The motivation of this paper is to accurately and efficiently simulate passenger flow dynamics in URT systems. To this end, a State-dependent Multi-agent Discrete...

The recent development of quantitative urban models provides a new set of tools for evaluating transport improvements. Conventional cost-benefit analyses are typically undertaken in partial equilibrium. In contrast, quantitative urban models characterize the spatial distribution of economic...

In the early 1990s, the London Underground was in need of significant investments. The British government argued that privatization would be an efficient solution to improve the quality of the infrastructure. Following the election of Tony Blair as prime minister in 1997, the government instead...

Urban rail transit plays a very important role in the social and economic development of cities. In order to ensure the safe and stable operation of urban rail transit operation equipment and facilities, it is necessary to monitor a large number of safety hazard status and data and improve the...

Underground railway systems are recognised spaces of increased personal pollution exposure. We studied the number-size distribution and physico-chemical characteristics of ultrafine (PM0.1), fine (PM0.1-2.5) and coarse (PM2.5-10) particles collected on a London underground platform. Particle...

This paper uses fare changes in Mexico City, Guadalajara, and Monterrey to estimate the price elasticity of demand for urban rail transit. In two of the cases there is a significant fare increase (30%+), and in the third there is a 60-day fare holiday. Ridership responds sharply in the expected...

The socioeconomic wellbeing of urban areas depends on a well-functioning transportation system that makes it easier for people to access goods and services. Whereas most urban areas in emerging economies are expanding in size and human population, high motorisation and inadequate public...

This paper shows and analyzes the deterioration of net social benefits from Line 3 of the Light Rail in Guadalajara, Mexico, which took place even before Line 3 began its operational life. According to this ex-post evaluation, this light rail project has performed worse than the average...

"Le métro de Paris a 125 ans. Des millions de voyageurs l'empruntent quotidiennement. Il est le résultat d'un pari, le fruit d'un demi-siècle de débats, de désaccords entre les tenants d'une extension parisienne des grands réseaux de chemins de fer de l'époque et ceux d'une desserte...

Urban rail transit (URT) networks serve a large amount of travel demand in metropolitan areas. One of the fundamental challenges in URT demand management is the dynamic interaction between train frequencies and passenger routing behaviors, which becomes even more complicated in oversaturated...

"Railway commuting is today a mundane and routine necessity, yet for the Victorians it was a novel experience. It opened up new possibilities of living at a remove from the crowded urban centre while staying connected to its places of work. Commuting helped transform London’s urban landscape,...

I analyze how housing markets in Espoo and Helsinki anticipate the construction of a new light rail transit connection called Jokeri Light Rail. I use geocoded micro-level housing transaction data from 2003-2019. As an econometric identification strategy, I utilize difference-in-differences...

It's important to explore ways to integrate bus and rail transit by combining both the effects of the built environment and their competition. Using Wuhan city in China as a case study, this study develops gradient boosting decision trees(GBDTs) to examine the threshold range of built...
