Highway construction occurs nowadays mainly through widening of existing roads rather than building new roads. This paper documents that highway widenings considerably reduce congestion in the short run, defined here as 6 years. Using longitudinal microdata from highway detector loops in the...

When traveling in an autonomous car, the travel time can be used for performing activities other than driving. This paper distinguishes users' work-related and home-related activities in autonomous cars and proposes an activity-based bottleneck model to investigate travelers' behavior in the...

We introduce a model of technological advances as allowing for greater productivity at the cost of increased complexity. Complex goods and services require a large number of strongly complementary inputs. Innovation increases the probability that an input will be flawed, leading to a skewed...

A.A. Walters derived a traffic flow function, and advocated toll to cure congestion. He wanted to save lives and monies, time is money, in congestion. NYC and Hong Kong have been practicing his policy for years, but surviving drivers are still tortured by congestion. Walters’ intention is...

Rising prices and reports of empty shelves in major economies have drawn attention to the functioning of supply chains that normally operate smoothly in the background. Among the issues, the long delays that port congestion may have caused in delivering goods to consumers and firms have been...

This paper addresses a new electricity-charging station location problem for congested intercity or regional networks, in which electric vehicles with a limited driving range require recharges for their long-distance trips. When the distribution of charging stations does not sufficiently cover...

In this paper, we construct commuters’ travel-time profiles, namely, the menu of travel times that each individual will likely face according to alternate trip timing choices, to measure congestion delays for morning commutes in California and explore a new trip scheduling pattern of commuters...

Urban infrastructure is essential to building sustainable cities. In recent years, municipal governments have invested heavily in the expansion of bike lane networks to meet growing demand, promote ridership, and reduce emissions. However, re-allocating vehicle capacity in a road network to...
