Preliminary Earthquake Mitigation Planning to Improve Watermain Performance in Vancouver, B.C.
City of Vancouver's water transmission and distribution system is vulnerable to over 1,000 pipe leaks or main breaks from a probable large earthquake (about 7.5 M). Cast iron...
Post Earthquake Investigation Team
The CALTRANS Post Earthquake Investigation Team (PEQIT) has been in existence since 1971. It is an emergency response team which mobilizes quickly following a major earthquake to gather...
Elevated Water Tank Inelastic Seismic Analysis
In 1988, the Seattle Water Department hired CYGNA, a consulting firm, to assess the seismic reliability of their water system, since major earthquakes can occur in the area. Their study...
Loss and Recovery of Critical Lifelines Following Recent Hurricanes
Hurricanes significantly affect the performance of critical lifelines. An overview of the loss and recovery of power supply, transportation, communication, and water/wastewater systems...
An Analytical Framework for Minimizing Freeway Incident Response Time
The reduction in incident delay is an important aspect of any freeway management program as it results in substantial savings to roadway users. This paper presents an integrated decision...
Optimal Ramp-Metering Control for Freeway Corridors
The paper discusses an optimal ramp-metering control model wherein a corridor is discretized into small road sections, with density as the state variable and ramp metering rates, the control...
Application of Control Theory to Regulate Traffic Flow on Periurban Ringways
Two on-ramp metering strategies are compared by a simulation study for the Boulevard Peripherique in Paris. The first one is a local strategy, based on linear feedback control theory....
Design and Evaluation of Multi-Band Progression Schemes
Multiband is a new arterial progression scheme that has the capability to assign each directional road section with an individually volume-weighted band. The method offers to the traffic...
Individual Traffic Information and Route Guidance from RDS-TMC Until Beacon Communication
A complete system of traffic management consisting of both collective and individual components is described. As a result of German and European initiatives problems, a system introduction...
Car Wars?The DOTs Strike Back
HNTB is developing integrated computer systems utilizing standard hardware and software platforms coupled with graphical user interfaces for traffic management systems (TMS). Rapid, user-friendly...
A New Approach for Real-Time Prediction of Traffic Demand-Diversion in Freeway Corridors
An adaptive method is developed for real-time prediction of demand and diversion of traffic flow at on-ramp areas of freeway corridors. The prediction method explicitly treats the time-variant...
Dynamic Stochastic Equilibrium Model in Multiple Vehicle Type Transportation Networks
In this study, a multi-vehicle type dynamic stochastic user equilibrium model (called MDSUE model for abbreviation) is developed. By using MDSUE model, the prediction of departure rates...
Dynamic Estimation of Freeway Demand Patterns and a Stochastic Programming Approach to Freeway Ramp Metering
Controlling the rate at which vehicles are allowed to enter a freeway from the freeway's on-ramps has become a standard method for reducing the impact of both recurring and...
Identify the Marina User Market and Make the Customer a Part of the Planning Team: Designing and Managing for the User's Needs
A practical surveying method is described which allows a marketing firm to simultaneously - and quantitatively - analyze demographic market composition (for both upland and in-water uses)...
The Marina Environment from a Boaters Point of View
A discussion of the benefits and problems encountered by the recreational boater as a tenant of both the public and private marinas in Southern California is presented....
Encouraging Tourism and Access Through Recreational Marina/Waterfront Design
Encouraging tourism and access through the development of recreational marina facilities challenges a community and marina designer to create a Master Plan which incorporates a wide range...
Development of Marina Facilities on the Southern California Coast
The Southern California coastal region has developed recreational boating facilities through the use of existing bays, creation of new inland water areas and the construction of small...
Marina Del Rey: 30 Years of Environmental Impact
Marina del Rey - the world's largest man-made recreational boating harbor - also holds primacy in pollution. Marina del Rey is home port to more than 6,100 vessels in wet...
NOAA Collection and Dissemination of Marine Information
