Road users have heterogeneous preferences regarding travel choices, such as time-of-day to travel, routes, and willingness to carpool. Understanding the variation in preferences would allow better modeling of the temporal distribution of travel demand and the development of pricing policies....

This paper analyses the efficiency and distributional impacts of congestion pricing in Vickrey's (1969) dynamic bottleneck model of congestion, allowing for continuous distributions of values of time and schedule delay. We find that congestion pricing can leave a majority of travellers better...

Unemployment durations are generally modelled by specifying the conditional probability of leaving unemployment (the hazard function). Existing studies for Britain all use very restrictive parametric specifications of the hazard function, mostly commonly Weibull in form. These restrictions...

In this study, we combined the advantages of bitmaps and remote sensing data to reconstruct three-dimensional (3D) harbor models and establish a new simulation navigation system. The models employ triangular elements to reconstruct the topology relationships between the seabed and the harbor...

Human hazards can represent a significant risk to the population and cause huge economic damage in many urbanized regions. In order to be able to identify risk hot spots and implement targeted risk reduction measures, decision makers need to have a clear picture of the risk situation in their...

The Sistan area is located in the east of Iran, enclosure to Afghanistan border. It is a densely populated enclave in the scarcely populated arid area of the eastern part of Iran, where the life strongly depends on the shallow water of Hamoun Lake and wetlands in the delta of the Helmand River...

The ability to model factors influencing land use can be significantly improved by incorporating variables derived from geographic information systems with more detailed survey data. While remote sensing data have the advantage of providing land cover measurements for large areas, survey data...

Purpose: Numerous stage models have attempted to clarify management priorities during the early stages of companies. However, a need for more focused and context-specific studies exists. This study seeks to clarify the early stages of technology- intensive companies in Southern California. To...

Severe economic recessionary times beginning in 1990 in southern California and the concurrent introduction of National Pollution Discharge Elimination System permit requirements provided a backdrop to evaluate Best Management Practices (BMP) cost effectiveness. This study analyzes municipal...

The California economy is in the doldrums, especially in the Los Angeles region, owing in large part to the decline of aerospace-defense industries. The region also suffers from the nation's worst pollution problem, owing largely to its dependence on automobiles. So, we're led to ask whether...
