Abstract: Urban growth and the resulting highway congestion is driving up demand for rail transit. Rail, a significant component of transportation infrastructure, is critical to economic efficiency and is one of the least energy-intensive ...

Abstract: Highway pavement maintenance is very expensive not only in terms of costs to the responsible agencies but also in terms of disruptive delays to users. Construction and maintenance activities on four-lane highways (with two ...

Abstract: Highway pavement maintenance is very expensive not only in terms of costs to the responsible agencies, but also in terms of disruptive delays to users. Construction and maintenance activities on two-lane, two-way highways ...

Abstract: Current analytic models for optimizing urban transit systems tend to sacrifice geographic realism and detail in order to obtain their solutions. The model presented here shows how an optimization approach can be successful ...

Abstract: The problem of determining an optimal feeder bus route, feeding a major intermodal transfer station (or a central business district), in a service area is considered. Subject to geographic, capacity, and budget constraints, ...

Abstract: Highway maintenance is very expensive in terms of not only costs to the responsible agencies but also disruptive delays to users. Construction and maintenance activities on two-lane two-way highways often require the closure ...

Abstract: Developing efficient operational strategies to improve service quality of bus transit, such as reducing travel time, can stimulate ridership. A mathematical model is formulated to optimize integrated bus service which ...

Abstract: The Road Weather Information System (RWIS) has been applied as an effective tool to collect weather and road surface temperature information and to assist operational decisions for snow and ice control activities. Current ...

Abstract: This study presents an approach to jointly optimize temporal service headway and differential fare for an intercity transit system considering heterogeneous demand elasticity. The research optimization problem is combinatorial ...
