Optimum Shape of Turnout Diverging Track with Segments of Variable Curvature
(American Society of Civil Engineers, 2019)This paper focuses on shaping the variable curvature in the diverging track of a railway turnout. Based on some earlier studies, solutions provided with a circular arc in the midzone and extreme regions with segments of ... -
Optimizing Work-Zone Schedule with Floating Car Data Considering Traffic Diversion and Managed Lanes
(American Society of Civil Engineers, 2019)Work zones have become the second largest contributor to the nonrecurring delay disruptions of traffic on US highways. The development of a sound model to minimize the total cost (i.e., road user cost and agency cost) ... -
Determinants of Bus Riding Time Deviations: Relationship between Driving Patterns and Transit Performance
(American Society of Civil Engineers, 2019)Urban bus services are subject to high levels of uncertainty and disturbances. Methods to determine the timetable are designed to absorb variations in riding times between stops by allocating additional travel time. The ... -
Modeling Trip-Length Distribution of Shopping Center Trips from GPS Data
(American Society of Civil Engineers, 2019)Automobile trip lengths are increasingly used in the calculation of development impact fees or bulk services contributions, affecting the revenue collected by local authorities. It is, however, difficult to obtain accurate ... -
Strategic Planning of Urban Network Evacuation with Balanced Signal Control and Crosselimination Strategies
(American Society of Civil Engineers, 2019)This paper addresses a critical operational issue of optimally converting some signalized intersections in an evacuation network into crosselimination control points to improve system performance. A mathematical model with ... -
Designing a Time Limited–Parking Management Plan for Large-Scale Parking Lots
(American Society of Civil Engineers, 2018)The time limited–parking management plan has been widely adopted in curbside parking and in terminal parking. This plan separates parking spaces into several parking groups and manages each group with a specific duration ... -
Uncertainty Propagation Assessment in Railway-Track Degradation Model Using Bayes Linear Theory
(American Society of Civil Engineers, 2018)Periodic inspection could be regarded as a form of insurance to check for variation in the performance of the empirical-based track degradation model. Excessive track inspection, however, hurts economic maintenance and ... -
Improved Railway Track Geometry Degradation Modeling for Tamping Cycle Prediction
(American Society of Civil Engineers, 2018)The railway track geometry condition is a key factor influencing the safety and comfort of train operations, and controlling the tamping cycles of railway tracks. For the scientific disposition of limited maintenance ... -
New Approach for Calibrating Robertson’s Platoon Dispersion Model
(American Society of Civil Engineers, 2018)A new approach for calibrating Robertson’s platoon dispersion model (RPDM) is proposed for addressing the issue of overestimation of time span of downstream vehicle arrival as predicted by the model Instead of comparing ... -
Relationship between Level of Service and Traffic Safety at Signalized Intersections: Grouped Random Parameter Method
(American Society of Civil Engineers, 2018)Level of service (LOS) is a measure recommended to evaluate the operational performance of roadway facilities. It is generally agreed that LOS is related to traffic safety at signalized intersections; however, this ... -
Expressway Visual Distance Detection Using Thermal Imager: Comparing Normal and Infrared Images
(American Society of Civil Engineers, 2018)The real-time monitoring of visibility for expressway traffic safety cannot be widely achieved due to the high cost of the traditional method. This paper proposes a novel method to monitor expressway visibility using two ... -
Optimizing Vehicle and Pedestrian Trade-Off Using Signal Timing in Intersections with Center Transit Lanes
(American Society of Civil Engineers, 2018)The construction of exclusive bus lanes is a strategy for giving priority to buses and improving the efficiency of the urban transportation system, and for that purpose, center transit lanes are an important type of transit ... -
Speed-Based Proximal Indicator for Right-Turn Crashes at Unsignalized Intersections in India
(American Society of Civil Engineers, 2018)Unsignalized intersections in India essentially function as uncontrolled ones due to the high prevalence of indisciplined traffic maneuverability. Right-turning vehicles from major and minor roads undertake risky crossing ... -
Effect of Dwelling Buses on the Traffic Operations of Nonmotor Vehicles at Bus Stops
(American Society of Civil Engineers, 2018)This study proposed a quantitative approach to evaluate the effects of dwelling buses on the traffic operations of nonmotor vehicles at stops in China. The primary objectives of this study were to compare the changes in ... -
Anomaly Detection and Cleaning of Highway Elevation Data from Google Earth Using Ensemble Empirical Mode Decomposition
(American Society of Civil Engineers, 2018)Elevation information and its derivation, such as grade, are very important in analyses of traffic operation, safety performance, and energy consumption on highways. Google Earth (GE) is considered a reliable source of ... -
Current Practices of Transportation Infrastructure Maintenance Investment Decision Making in the United States
(American Society of Civil Engineers, 2018)Public infrastructure is facing many challenges resulting in capacity reduction capped with funding limitation. Thus, not only is significant funding required to maintain the infrastructure under the current challenges, ... -
