Tendency-Based Approach for Link Travel Time Estimation
(American Society of Civil Engineers, 2013)From the historical bus trajectories, it was found that the headway bias amplified as buses travel on the route. When controls on buses are unavailable, the following buses will maintain the movement tendency toward their ... -
Accounting for Network Effects in Railway Asset Management
(American Society of Civil Engineers, 2013)System-level infrastructure management involves determining optimal maintenance, rehabilitation, and reconstruction activities for a system of facilities over a planning horizon to maximize the level of service subject to ... -
Detection of Quiet Vehicles by Blind Pedestrians
(American Society of Civil Engineers, 2013)This paper examines participants who are blind, with and without normal hearing, regarding detection of forward approaching and backing vehicles operating in electric mode (identified in this paper as quiet vehicles) under ... -
Modeling the Methods of Flexible Pavements Maintenance
(American Society of Civil Engineers, 2014)This paper describes the development of Evaluation of Pavement Condition Model software (EPCM), which consists of three main elements. The first element deals with a road network definition to create a database for each ... -
Modeling Bicycle Passing Maneuvers on Multilane Separated Bicycle Paths
(American Society of Civil Engineers, 2013)Bicycle passing maneuvers represent interferences between bicycle travelers and are important operational attributes of bicycle traffic. The number of bicycle passing maneuvers has been used to evaluate the level of service ... -
Passenger Traffic Characteristics of Service Facilities in Rail Transit Stations of Shanghai
(American Society of Civil Engineers, 2013)The configuration of service facilities, such as ticket vending machines, staffed ticket booths, automatic fare gates, and escalators, is an important issue for the plan and design of rail transit stations. Reasonable ... -
Numerical Modeling of High-Speed Train/Track System to Assess Track Vibrations and Settlement Prediction
(American Society of Civil Engineers, 2013)The circulation of trains at very high speeds (higher than -
Optimizing Electric Rail Energy Consumption Using the Lagrange Multiplier Technique
(American Society of Civil Engineers, 2013)In the railway sector, one of the sensitive issues to be borne very much in mind is the cost brought about by the energy consumption required to meet schedules, be they local trains, metropolitan systems, or long-distance ... -
Division Method for Waiting Areas on Island Platforms at Metro Stations
(American Society of Civil Engineers, 2013)A metro station island platform in China takes a high density of passenger flow. For security and energy reasons, most metro stations have installed fully enclosed and semienclosed platform screen doors (PSDs), which causes ... -
Combinatorial Optimization of Exclusive Bus Lanes and Bus Frequencies in Multi-Modal Transportation Network
(American Society of Civil Engineers, 2012)Bus priority strategy has widely been recognized as an effective countermeasure in the practical field of urban traffic congestion mitigation. This study proposes a bi-level programming model to comprehensively analyze the ... -
Joint Optimization of Temporal Headway and Differential Fare for Transit Systems Considering Heterogeneous Demand Elasticity
(American Society of Civil Engineers, 2013)This study presents an approach to jointly optimize temporal service headway and differential fare for an intercity transit system considering heterogeneous demand elasticity. The research optimization problem is combinatorial ... -
Rail Track Performance with Different Subballast Solutions: Traffic and Environmental Effects on Subgrade Service Life
(American Society of Civil Engineers, 2012)This paper discusses the effect of using different subballast solutions in the overall performance of the substructure on the basis of a methodology suitable to account for the effects of rail traffic loading and environmental ... -
Cost Estimating Model for Mode Choice between Light Rail and Bus Rapid Transit Systems
(American Society of Civil Engineers, 2013)A cost estimating model is developed for light rail transit (LRT) and bus rapid transit (BRT) systems to better aid transportation planners and decision makers in the selection process. In evaluating transit systems, cost ... -
Economic Effect of High-Speed Rail: Empirical Analysis of Shinkansen’s Impact on Industrial Location
(American Society of Civil Engineers, 2012)High-speed rail in infrastructure construction has become a priority worldwide, and vast investments have been made; therefore, it has become increasingly necessary to appropriately assess regional economic impact, and ... -
Decision Model for Justifying the Benefits of Detour Operation under Non-Recurrent Congestion
(American Society of Civil Engineers, 2013)Non-recurrent traffic congestion due to incidents, highway construction zones, and special events has contributed up to 60% of the total freeway corridor delay in the United States. Under most scenarios, if proper diversion ... -
Numerical Simulation of Inverted Pavement Systems
(American Society of Civil Engineers, 2012)Conventional pavements rely on stiff upper layers to spread traffic loads onto less rigid lower layers. In contrast, an inverted pavement system consists of an unbound aggregate base compacted on top of a stiff cement-treated ... -
Safety Effect of U-Turn Conversions in Tehran: Empirical Bayes Observational Before-and-After Study and Crash Prediction Models
(American Society of Civil Engineers, 2013)Directional midblock median openings with left-turn lanes and loons were installed on major highways in Tehran, Iran, to prohibit direct left turns from major and minor roadways and to prevent through movements of minor ... -
Microsimulation Approach for Predicting Crashes at Unsignalized Intersections Using Traffic Conflicts
(American Society of Civil Engineers, 2012)A microsimulation approach is presented for assessing safety at unsignalized intersections using critical traffic conflicts computed in simulation models as a surrogate safety measure. The proposed approach was applied to ... -
