Accident-Oriented Delay Propagation in High-Speed Railway Network
(ASCE, 2020)This paper presents an approach to estimate the delay propagation in a high-speed railway (HSR) network under accident conditions. Considering the complexity and dynamics of HSR accidents, different levels of delay are ... -
ITS Technologies for Decision Making during Evacuation Operations: A Review
(ASCE, 2020)As natural and human-induced disasters have increased in recent years in number, magnitude, and impacts, the frequency of evacuation orders is expected to be accordingly raised in the future. Practice has shown, however, ... -
Impact of Arterial BRT-Lite Green Dwell Time on General Traffic and Intersection Capacity
(ASCE, 2020)This paper studies the effect dwelling mixed-traffic arterial Bus Rapid Transit (BRT-“Lite”) buses have on general traffic conditions and intersection capacity. Queue length and flow rate data collected from the busiest ... -
Effects of Driverless Vehicles on Competitiveness of Bus Transit Services
(ASCE, 2020)The advent of driverless vehicles, including automobiles and buses, may considerably affect the competitiveness and ridership of public transportation services in negative as well as positive ways. Since driverless vehicles ... -
Network Design with Elastic Demand and Dynamic Passenger Assignment to Assess the Performance of Transit Services
(ASCE, 2020)This study proposes a solution framework for operational analysis and financial assessment of transit services that considers the passenger behavior and the elasticity of transit demand to service characteristics. The ... -
Influence of Nonmotorized Vehicles on Speed Characteristics and Capacity of Mixed Motorized Traffic of Urban Arterial Midblock Sections
(ASCE, 2020)Traffic stream characteristics are largely influenced by the presence of nonmotorized vehicles (NMVs) when mixed with the motorized vehicles in a non-lane-based heterogeneous traffic stream. The traffic stream operation ... -
Alternative Methods for Estimating Seasonal Factors and Accuracy of Daily Volumes They Yield
(ASCE, 2020)The Federal Highway Administration requires each state department of transportation to have a traffic monitoring program for estimation of among others annual average daily traffic (AADT), a performance measure that guides ... -
Development of Railway Ride Comfort Prediction Model: Incorporating Track Geometry and Rolling Stock Conditions
(ASCE, 2020)Passenger ride comfort (PRC) is one of the most important performance indicators of railway transportation. The current methods for computation and evaluation of railway ride comfort require measurement of train accelerations ... -
Safety Implications of Converting Continuous Green T-Intersections Back to Conventional T-Intersections
(ASCE, 2020)A continuous green T-intersection (CGT) is an innovative intersection that can improve the through traffic capacity by allowing major-leg vehicles on the top side of the T-intersection to pass through without stopping. ... -
Gap between Policymakers’ Priorities and Users’ Needs in Planning for Accessible Public Transit System
(ASCE, 2020)Access to public transit forms a vital part of the well-being of people with disabilities. However, people with disabilities continue to be challenged in accessing their local transit services. This study investigates the ... -
Predicting Traffic Conflicts for Expressway Diverging Areas Using Vehicle Trajectory Data
(ASCE, 2020)Traffic crashes occur frequently in expressway diverging areas. The influential factors for traffic crashes in expressway diverging areas were investigated in this study using vehicle trajectory data. An hourly conflict ... -
Analysis of Traffic Properties of Commuters in a Speed-Limit Corridor with Toll Station under Microscopic Method
(ASCE, 2020)This study applies the full velocity difference (FVD) model to investigate commuters’ driving process in a speed limit corridor with a toll station and explains how some factors affect the outflow of the traffic corridor ... -
Dynamic Eco-Driving near Signalized Intersections: Systematic Review and Future Research Directions
(ASCE, 2020)Advancements in the field of telematics have empowered the development of connected vehicle (CV) applications, which optimize the energy and traffic efficiency of vehicular traffic. Over the past decade, various research ... -
Two-Step Coordinated Optimization Model of Mixed Demand Responsive Feeder Transit
(ASCE, 2020)It is necessary to consider both the reservation and real-time travel demand in order to coordinate and optimize vehicle routing and scheduling. In this paper, a two-step coordinated optimization methodology is proposed ... -
Analytical Method of Connecting Parallel Tracks Located in a Circular Arc Using Curved Turnouts
(ASCE, 2020)The paper focused on the issue of curving railroad turnouts in order to use them to connect parallel tracks located in a circular curve on a double-track line. An analytical method of recording was applied, which gave ... -
Nighttime versus Daytime Horizontal Curve Design Consistency: Issues and Concerns
(ASCE, 2020)Approximately 47% of fatal crashes in the US and 36% in the European Union occur during the night. Reduced sight distance may contribute to this phenomenon and similar speeds driven between day and night can become problematic ... -
Managing Alaska’s Road-Dust Problem: A Model for Road Dust–Impacted Regions
(ASCE, 2020)Poor air quality in Alaska’s remote communities due to road dust is one of the top environmental concerns of residents in these communities. Most communities are disconnected from the road network, with community roads ... -
Statistical Prediction of Center Negative Bending Capacity of Pretensioned Concrete Crossties
(ASCE, 2020)When concrete railway crossties are installed in North American freight track and subjected to flexural loads, center negative bending is one of the most critical demands. However, the ultimate flexural capacity at the ... -
Safety Evaluation of Arterials under Signal Coordination Considering the Correlated Heterogeneity and Multivariate Spatial Correlation
