Day-to-day traffic (DTD) dynamic systems have attracted much attention recently as a powerful tool to describe the evolution of network flows over time. A number of DTD models adopting various behavioral principles have been proposed, but for most of them, either their assumptions are introduced...

We study whether subways alleviate road congestion by examining 45 subway line launches in China and using detailed data on road speed. Our difference-in-differences estimation finds that in the first year after a subway line is launched, rush-hour speed on nearby roads increases by about 4%....

It is obvious that holding city population constant, differences in cities across the world areenormous. Urban giants in poor countries are not large using measures such as land area,interior space or value of output. These differences are easily reconciled mathematically aspopulation is the...

An analysis of the freight costs of Russian foreign trade cargos shows that the quality characteristics of Russia's seaports have a strong bearing on the sea freight routing – seaports with low-quality infrastructure are apt to lose the competition. Not only Russia's economic policy in the...

The hidden costs of congestion are between $500 million and $1.2 billion a year for the Metro Vancouver area, according to a new report from the C.D. Howe Institute. In “Tackling Traffic: The Economic Cost of Congestion in Metro Vancouver,” author Benjamin Dachis finds that when congestion...

Under its “Greenlight Pinellas” proposal, the Pinellas Suncoast Transit Authority (PSTA), which serves Pinellas County, FL, wants to switch its major funding source from a property tax to a sales tax at a rate that will more than double its local tax revenues, and use the added money to...

Prompted by federal funding, more than 30 American cities have built or are building new rail transit lines. These expensive lines have debatable value as they put transit agencies in debt and impose high maintenance costs, yet they carry few riders more than the buses they replace and produce...

Most new rail transit lines in the United States and around the world are either light rail, including lines that sometimes run in or cross city streets, or heavy rail, which are built in exclusive rights of way, usually elevated or in subways. Heavy rail costs far more to build than light rail,...

This paper develops a practical approach to estimate the benefits of improved reliability of road networks. We present a general methodology to estimate the (changes in) scheduling costs due to (changes in) travel time variability for car travel. We focus on situations where only mean delays are...
