Abstract: Accessibility, proximity, and land-use changes over time are important considerations in highway route selection. Highway users while benefiting from living closer to highways also pay a price for living close to them due ...

Abstract: In railroads, the vertical alignment design is closely related to the cost of operation because it may affect the required energy consumptions. By considering an innovative vertical alignment design concept such as the ...

Abstract: A method for precisely formulating intersection construction costs including earthwork costs, right-of-way costs, and pavement costs is introduced in this paper. Intersection design characteristics are reviewed and ...

Abstract: In this paper two vertical alignment profiles (labeled dipped and undipped) connecting rail transit stations with different elevations are compared. A deterministic simulation model is developed and used to analyze train ...

Abstract: Vertical alignment profiles are generally governed by geographical constraints; however, vertical alignment design is important, as it may significantly affect operating decisions such as travel time and tractive and braking ...

Abstract: A three-dimensional highway alignment optimization methodology is developed that automatically determines whether and where bridges or tunnels are preferable to embankments or deep cuts, respectively. This is done by ...
