Maglev Guideway Cost and Construction Schedule Assessment
(American Society of Civil Engineers, 1997)A summary of construction cost and scheduling information is presented for four maglev guideway designs on an example route from Baltimore, MD to Newark, N.J. This work results from the National Maglev Initiative (NMI), a ... -
Carrying Freight on High-Speed Rail Lines
(American Society of Civil Engineers, 1997)Under the current economic climate it is expected that any new high-speed rail line in the United States would be constructed as a public/private partnership, requiring substantial private investment, and thus the expectation ... -
Designing Concrete EDS Maglev Guideways: Power Losses in Metallic Reinforcement
(American Society of Civil Engineers, 1997)Conventional reinforced concrete designs will have to be altered when designing a guideway for a maglev using an electrodynamically suspended (EDS) propulsion system. This type of propulsion system generates large magnetic ... -
Modeling Demand for Public Transit Services in Rural Areas
(American Society of Civil Engineers, 1997)Accurate estimates of demand are critical for planning, designing, and operating public transit systems. Previous research has demonstrated that the expected demand in rural areas is a function of both demographic and ... -
Modeling Approach for Transit Rolling-Stock Deterioration Prediction
(American Society of Civil Engineers, 1997)An effective public transportation management system (PTMS) requires accurate and efficient models for the prediction of rolling-stock conditions. If the state of any given rolling-stock unit is known, its future condition ... -
Incident Detection Using Vehicle-Based and Fixed-Location Surveillance
(American Society of Civil Engineers, 1997)Many recent intelligent transportation systems (ITS) deployments feature vehicle probes as prominent sources of information about traffic conditions in addition to, or in place of, fixed-location measurement devices such ... -
Analysis of Crosstie Track in Lateral Plane Using New Track Equations
(American Society of Civil Engineers, 1997)The analysis of a crosstie railroad track in the lateral plane has traditionally been based on the theory of a beam on an elastic foundation, in which the bending rigidity of the track structure is assumed to be twice the ... -
Review of Models Combining Traffic Assignment and Signal Control
(American Society of Civil Engineers, 1997)This paper reviews a class of models that combine equilibrium traffic assignment and intersection control into a single analysis framework under the assumption of flow-responsive signal settings. The most significant feature ... -
Structural Performance of Inservice Flexible Pavements
(American Society of Civil Engineers, 1997)Due to the combined influence of traffic loading and environment, the structural condition of pavement deteriorates with time. Studies on structural damage, which usually results in functional deterioration, is important ... -
Structural Evaluation of Maglev Guideway Concepts
(American Society of Civil Engineers, 1997)The National Maglev Initiative (NMI) resulted in four distinctly different concepts. The structural systems of the concepts varied greatly, but in general were very complex. This paper evaluates the concepts as to their ... -
Design Criteria for Maglev Structures
(American Society of Civil Engineers, 1997)Maglev systems represent an entirely new concept in transportation. They will not operate on nor share the right-of-way with any other system. It is important, therefore, that the guideways be designed and constructed so ... -
Discussion and Closure: Basics of Flexible Pipe Structural Design
(American Society of Civil Engineers, 1997) -
HSGT Corridor Planning: Land-Use and Other Considerations
(American Society of Civil Engineers, 1997)This paper explores land-use and other considerations in planning for high-speed ground transportation (HSGT) systems in the United States. Beyond the critical issue of project financing, upon which all HSGT projects ... -
Maintenance Strategy Optimization of Bridge Decks Using Genetic Algorithm
(American Society of Civil Engineers, 1997)With the rapidly increasing requirements of bridge maintenance and the limited budget available for this maintenance, the cost optimization of long-term maintenance strategy considering the network-level bridge system under ... -
Maglev Guideway Design Issues
(American Society of Civil Engineers, 1997)This paper reports results from guideway analyses conducted as part of the National Maglev Initiative (NMI), a government-industry effort from 1989 to 1994, formed to encourage the development of U.S. maglev technology and ... -
Probabilistic Speed-Estimation Measurement Errors through Video Images
(American Society of Civil Engineers, 1997)Many data-collection methods are available from simple manual methods to advanced automatic image processing techniques. For many practical purposes video recording has become a widely used tool. Though this method is ... -
Temperature Effects on Cellular Rigid Pavement Compared to Flat Slabs
(American Society of Civil Engineers, 1997)Temperature effects on rigid pavements have been shown to be significant fatigue contributors in combination with stresses produced by load, particularly at slab corners. A construction method for rigid pavement utilizing ... -
Calibration of Pavement Design Models Using Field Data
(American Society of Civil Engineers, 1997)This paper provides a framework for the development of Weibull reliability factors (since they describe “length of life” or endurance over time) for joint faulting models using field data from the Strategic Highway Research ... -
Using Accident Correctability to Identify Accident-Prone Locations
(American Society of Civil Engineers, 1997)In traditional black-spot programs aimed at improving highway safety, locations are identified as accident prone based on the total number of accidents. This criteria provides no consideration of whether the accidents were ... -
Assessment of Concrete Pavement Blowups
(American Society of Civil Engineers, 1997)The assessment is based on the analyses of pavement blowups presented by the writer and his coworkers Dallis and Shade. The introduction reviews briefly the various early attempts to clarify the blowup phenomenon. The next ...
