Applicability Analysis of an Extended METANET Model in Traffic-State Prediction for Congested Freeway Corridors
(American Society of Civil Engineers, 2018)Macroscopic traffic flow models are often applied as prediction models in proactive traffic control strategies. For model calibration and validation, existing tests have been conducted on simple freeway corridors, meaning ... -
Crash Prediction Model for Basic Freeway Segments Incorporating Influence of Road Geometrics and Traffic Signs
(American Society of Civil Engineers, 2018)Dividing a freeway into segments is a fundamental step in establishing its crash prediction model. Instead of using the common segmentation criteria that defines short segments as homogeneous as possible, this study used ... -
Optimum Capacity of Freeways: A Stochastic Approach
(American Society of Civil Engineers, 2018)This study explores a practical value for highway capacity that is able to represent stochastic capacity and optimize the performance of designed facilities. Optimal performance of roadways could be defined in terms of ... -
Land Development and Traffic Composition at Rural Interstate Highway Interchanges in Ohio
(American Society of Civil Engineers, 2018)Highway interchanges, particularly those in rural areas, offer fertile opportunities for highway-oriented land development such as gas stations, convenience stores, restaurants, and hotels. This paper presents an exploratory ... -
Validation of an Outdoor Coast-Down Test to Measure Bicycle Resistance Parameters
(American Society of Civil Engineers, 2018)Bicyclist rolling and aerodynamic resistance parameters are needed to estimate speed and energy expenditure in various travel analysis applications. These parameters have been investigated for sport and professional ... -
Beyond Standard Zonal Congestion Pricing: A Detailed Impact Analysis
(American Society of Civil Engineers, 2018)This study formulates three fundamental extensions of the standard optimal road use analysis: (1) considering fuel and emissions as variable costs, (2) maximizing the social welfare inside and outside the congestion ... -
Managing Day-to-Day Network Traffic Evolution via an Altering Ex-Post Information Release Strategy
(American Society of Civil Engineers, 2018)Providing travelers with full ex-post travel time information from day to day can only make a disequilibrium network evolve to the user equilibrium, rather than the system-optimal or other better-off states. To make best ... -
New Microscopic Dynamic Model for Bicyclists’ Riding Strategies
(American Society of Civil Engineers, 2018)As more attention is focused on bicycles as a mode of transportation, there is a strong need to understand microscopic behaviors of bicyclists within urban traffic systems. To respond to these needs, a new approach to ... -
Tabu Search Strategies for Variable Speed Limit Control at a Lane Drop Bottleneck
(American Society of Civil Engineers, 2018)A tabu search–based algorithm is developed in this study and applied for optimizing a variable speed limit (VSL) control system. A macroscopic traffic flow model is used to predict the traffic states over the prediction ... -
Identifying Bottlenecks in Roadway Networks in Hurricane Evacuation
(American Society of Civil Engineers, 2018)The existence of traffic bottlenecks limits the network capacity and leads to massive recurring and nonrecurring congestions during daily traffic peaks and in the critical event of an emergency evacuation. It is important ... -
Stability Analysis of Connected and Automated Vehicles to Reduce Fuel Consumption and Emissions
(American Society of Civil Engineers, 2018)Obtaining an optimal stability condition is very important to benefit traffic flow operations for a mix of connected and automated vehicles (CAVs) and regular vehicles. In view of multiple spatial anticipations of CAV ... -
Effect of Highway Lane Management Policy of Heavy Vehicles on the Cost of Flexible Pavement
(American Society of Civil Engineers, 2018)Truck lane restriction is one of the most common highway lane management strategies; it ensures that heavy vehicles mostly use the outer lanes of a multilane highway. A higher percentage of heavy vehicles in the design ... -
Examining Injury Severity of Moped and Motorcycle Occupants with Real-Time Traffic and Weather Data
(American Society of Civil Engineers, 2018)Currently studies exploring the effect of real-time traffic and weather characteristics on crash severity are relatively limited, and studies focusing on powered two-wheelers (PTWs) are even fewer. The objective of this ... -
Safety Analysis of Access Zone Design for Managed Toll Lanes on Freeways
(American Society of Civil Engineers, 2018)On freeways, managed lanes (MLs) have emerged as an effective dynamic traffic management strategy. MLs have been successfully implemented as an important facility in improving traffic mobility and generating revenue for ... -
Exploring Evasive Action–Based Indicators for PTW Conflicts in Shared Traffic Facility Environments
(American Society of Civil Engineers, 2018)Surrogate safety measures such as traffic conflicts are gaining more and more attention for traffic safety analysis. The traffic conflict technique evaluates the frequency and severity of traffic conflicts at a location ... -
Modeling Actual Dwell Time for Rail Transit Using Data Analytics and Support Vector Regression
(American Society of Civil Engineers, 2018)Actual dwell time (DT) at rail transit stations is one of the most significant and useful parameters in evaluating the scheduled timetable and making any dynamic operation adjustments as necessary. It can be influenced by ... -
