This paper investigates variable speed limit (VSL) systems, trying to optimize the system designs when the variable message signs (VMSs) are movable. The optimization problem is formulated as a large mixed-integer nonlinear programming problem, whose decision variables include the number of VMSs to be deployed, the locations of the VMSs, and the speed(More)
Destination choice, especially shopping-destination choice always has a very large number of alternatives. Estimating such model from the entire population can be very expensive or impossible. By using the real survey data from Dallas-Forth Worth (DFW) area, this project estimates the same empirical shopping-destination choice using different sampling(More)
