Smart Real-Time Vehicle Detection and Tracking System Using Road Surveillance Cameras
(ASCE, 2022/10/01)Several traffic studies necessitate vehicle counting during peak hours and throughout the day, as well as detailed classification and tracking, which consumes human time and effort, particularly at intersections. Manual ... -
Safety Effectiveness and the Role of Geometric, Traffic, and Crash History–Related Factors in Converting a Stop-Controlled Intersection to a Miniroundabout
(ASCE, 2022/10/01)The focus of this paper is on evaluating the safety effectiveness of converting a stop-controlled intersection with a speed limit≥56.3 km/h (35 mi/h) to a miniroundabout and examining the role of influencing factors on ... -
Robustness Quantification of Transit Infrastructure under Systemic Risks: A Hybrid Network–Analytics Approach for Resilience Planning
(ASCE, 2022/10/01)Disruptions due to either natural or anthropogenic hazards can significantly impact the operation of critical infrastructure networks (e.g., transportation systems) as they may instigate network-level (cascade) systemic ... -
A Decision Support Tool for Accommodating Right-Turning Trucks at Urban Intersections in Walkable Communities
(ASCE, 2022/10/01)Many North American jurisdictions are creating walkable urban environments through compact Complete Streets (CS) geometric designs, while not addressing the mobility and accessibility of goods despite the essential role ... -
Spatial Interpolation–Based Localized Growth Factors Compared to Statewide, Regional-Level, and County-Level Growth Factors for Local Roads
(ASCE, 2022/07/15)The focus of this paper is on developing localized growth factors for estimating annual average daily traffic (AADT) of a local, functionally classified road (referred to herein as a local road). Statewide, regional-level, ... -
Evaluation of Direct and Indirect Safety Effects of Speed-Limit Reduction on Urban Networks
(ASCE, 2022/07/18)This study develops a set of crash modification factors (CMFs) to evaluate the effects of lowering urban-road speed limits on vehicle and pedestrian safety. Cross-sectional methods and observation before–after methods are ... -
Improved Horizontal Curve Design Consistency Approach Using Steady-State Bicycle Model Combined with Realistic Speeds and Path Radii
(ASCE, 2022/07/15)Three safety concerns have been identified in the conventional design consistency assessment procedure for horizontal curves: approximation of the vehicle by the point-mass model, use of unrealistic speeds, and the assumption ... -
Waiting Time Estimation at Ferry Terminals Based on License Plate Recognition
(ASCE, 2022/07/12)The ferry transit system provides a critical transportation link in coastal areas for both residents and tourists. Like signals in a road network, queuing and waiting are unavoidable at ferry terminals. However, a reliable ... -
Recognizing Real-Time Transfer Patterns between Metro and Bus Systems Based on Spatial–Temporal Constraints
(ASCE, 2022/07/13)The transfer between bus and metro is an integral part of the public transportation system, but accurately identifying transfer patterns and real-time transfer demands at each metro station for different transfer modes ... -
Evaluating the Pedestrian Gap Acceptance in Semicontrolled Midblock Crosswalks with an Integrated AHP-FL Approach
(ASCE, 2022/07/13)Gap acceptance, the fundamental part of pedestrian crossing behavior, represents a pedestrian’s assessment of how safe an existing gap in traffic flow is to cross the path. This assessment is an essential factor affecting ... -
Validation of Machine Learning Algorithms as Predictive Tool in the Road Safety Management Process: Case of Network Screening
(ASCE, 2022/07/14)Safety performance functions (SPFs) are the key regression tools in the road safety management process (RSMP) and are used to predict crash frequency given a set of roadway and traffic factors. Although regression-based ... -
Random-Parameter Bayesian Hierarchical Extreme Value Modeling Approach with Heterogeneity in Means and Variances for Traffic Conflict–Based Crash Estimation
(ASCE, 2022/06/21)Using random parameters in combination with extreme value theory (EVT) models has been shown to capture unobserved heterogeneity and improve crash estimation based on traffic conflicts. However, in existing random-parameter ... -
When to Charge a Small-Range Battery Electric Vehicle: Refining Charging Strategies Using a Scenario-Based Approach
(ASCE, 2022/07/14)Small-range battery electric vehicles (BEVs), with driving ranges less than 200 km, are susceptible to charging defects. This study applied a scenario-based approach by modeling a cost function to recommend an optimal ... -
