Public transit accounts for 1 percent of US passenger miles traveled but attracts strong public support. Using a simple choice model, we predict that transit riders are likely to be individuals who commute along routes with severe roadway delays. These individuals' choices thus have high marginal impacts on congestion. We test this prediction with data from a strike in 2003 by Los Angeles transit workers. Estimating a regression discontinuity design, we find that average highway delay increases 47 percent when transit service ceases. We find that the net benefits of transit systems appear to be much larger than previously believed.

This study assesses the impact of proximity to light rail transit stations on residential property values in Buffalo, New York, where light rail has been in service for 20 years, but population is declining and ridership is decreasing. Hedonic models are constructed of assessed value for residential properties within half a mile of 14 light rail stations and independent variables are included that describe property characteristics, neighbourhood characteristics and locational amenities. The model suggests that, for homes located in the study area, every foot closer to a light rail station increases average property values by $2.31 (using geographical straight-line distance) and $0.99 (using network distance). Consequently, a home located within one-quarter of a mile radius of a light rail station can earn a premium of $1300-3000, or 2-5 per cent of the city's median home value. Model results further suggest that three independent variables—the number of bathrooms, size of the parcel and location on the East side or West side of Buffalo—are more influential than rail proximity in predicting property values. Individual regression models for each of the light rail system's 14 stations suggest that effects are not felt evenly throughout the system. Proximity effects are positive in high-income station areas and negative in low-income station areas. An analysis of the actual walking distance to stations (along the street network) versus the perceived proximity to stations (measured by straight-line distance) reveals that the results are statistically more significant in the network distance than the straight-line distance model, but the effects are greater in the straight-line distance model, which suggests that apparent proximity to rail stations is an added locational advantage compared with physical walking distance to the station.

In April2009, the U.S. government unveiled its blueprint for a national network of high-speed passenger rail (HSR) lines, aimed at reducing traffic congestion, cutting national dependence on foreign oil, and improving rural and urban environments. In implementing such a project, it is essential to identify the factors that might influence decision making and the eventual success of the HSR project, as well as to foresee the obstacles that must be overcome. The authors review, summarize, and analyze the most important HSR projects carried out to date around the globe, focusing on the main concerns of HSR projects: their impact on mobility, the environment, the economy, and urban centers. The authors identify lessons for policy makers and managers who are implementing HSR projects.

A ticket from London to Istanbul on the Orient Express network meant crossing continents in style. Beyond the Balkans, Sofia offers a stark reminder of a country with a troubled past. Further south, a royal palace hides exotic surprises in its grounds. The train's final destination: Istanbul, where East meets West, and the unexpected always feels possible.

Passengers could buy a ticket from London to Istanbul on the Orient Express network. Travelling east through Austria, they might stop in its capital to meet the father of psychoanalysis, whose own flight to freedom is forever linked to the legendary train. Then on to the City of Spas, home to one of the world's longest and fastest tram lines, run entirely by children.

This study explores the complex process of transit and land-use integration in rapidly growing cities in developing countries. It first identifies barriers to and opportunities for effective coordination of transit infrastructure and urban development. It then recommends a set of policies and implementation measures for overcoming these barriers and exploiting these opportunities. Well-integrated transit and land development create urban forms and spaces that reduce the need for travel by private motorized vehicles. Areas with good access to public transit and well-designed urban spaces that are walkable and bikeable become highly attractive places for people to live, work, learn, play, and interact. Such environments enhance a city's economic competitiveness, reduce local pollution and global greenhouse gas emissions, and promote inclusive development. These goals are at the heart of transit-oriented development (TOD), an urban form that is increasingly important to sustainable urban futures. This book uses a case study approach. It draws lessons from global best-case examples of transit-oriented metropolises that have direct relevance to cities in developing countries and elsewhere that are currently investing in bus rapid transit (BRT) and other high-capacity transit systems. It also reports the results of two original in-depth case studies of rapidly growing and motorizing cities that introduced extended BRT systems: Ahmedabad, India and Bogota, Colombia. Two shorter case studies enrich the understanding of factors that are critical to transforming cities with transit.

Will a group of people reach a collective target through individual contributions when everyone suffers individually if the target is missed? This \"collective-risk social dilemma\" exists in various social scenarios, the globally most challenging one being the prevention of dangerous climate change. Reaching the collective target requires individual sacrifice, with benefits to all but no guarantee that others will also contribute. It even seems tempting to contribute less and save money to induce others to contribute more, hence the dilemma and the risk of failure. Here, we introduce the collective-risk social dilemma and simulate it in a controlled experiment: Will a group of people reach a fixed target sum through successive monetary contributions, when they know they will lose all their remaining money with a certain probability if they fail to reach the target sum? We find that, under high risk of simulated dangerous climate change, half of the groups succeed in reaching the target sum, whereas the others only marginally fail. When the risk of loss is only as high as the necessary average investment or even lower, the groups generally fail to reach the target sum. We conclude that one possible strategy to relieve the collective-risk dilemma in high-risk situations is to convince people that failure to invest enough is very likely to cause grave financial loss to the individual. Our analysis describes the social window humankind has to prevent dangerous climate change.

One of the promising areas of improvement of sensors for monitoring the condition of track sections is the development of controlling sensors, which are less dependent on changes in ballast resistance, longitudinal asymmetry and standard value of shunt sensitivity, such a direction is the development of adaptive track circuits [1-5]. The article proposes a control sensor with an adaptive receiver, principle of operation of which is that monitoring the state of the track section depends on the parameters of adjacent monitoring sensors, included in the common controlled zone CZ. Mathematical model and analytical expressions have been developed taking into account the resistance of the rails and the resistance of the insulation being carried out [6]. Proposed the coefficients of a rail fourpole with one of the choke-transformer, powered with one side. The calculated expressions of the fourpole and the criteria for the sensitivity of the rail circuit when one line is broken are presented and derived, and also the minimum transmission resistance [6].
