Abstract: This research contributes to the theoretical basis for design of integrated planning information systems. The research provides a framework for integrating relevant knowledge, theory, methods, and technology. The requirements ...

Abstract: An optimal trip table correction function for the user equilibrium based trip table estimation problem is derived and used in place of Turnquist and Gur's heuristic trip table correction function. The derivation of this ...

Abstract: There is a prevailing assumption that Freeway Service Patrol (FSP) programs improve safety for unassisted motorists by reducing the likelihood of secondary accidents. This research identifies 84,684 accident records from ...

Abstract: Regional economic impact models (REIMs) are needed for performance-based earthquake engineering and similar activities. The metropolitan-level performance measures that can be supported by earthquake engineering outputs ...

Abstract: This research assessed the feasibility of using trucks in an existing Los Angeles Freeway Service Patrol (FSP) fleet as probe vehicles to measure ambient speed on freeway segments. Floating car speeds were the basis of ...

Abstract: Monte Carlo simulation techniques are used with bridge fragility curves to evaluate bridge damage in terms of a bridge damage index, and highway network link damage in terms of a link damage index. Static, user-equilibrium ...
