Identifying High-Risk Intersections for Walking and Bicycling Using Multiple Data Sources in the City of San Diego
(Hindawi, 2019-06-16)
Over the last decade, demand for active transportation modes such as walking and bicycling has increased. While it is desirable to provide high levels of safety for these eco-friendly modes of travel, unfortunately, the ...
Feasibility Study for Using Piezoelectric-Based Weigh-In-Motion (WIM) System on Public Roadway
(MDPI, 2019-07-31)
Weigh-in-Motion system has been the primary selection of U.S. government agencies as the weighing enforcement for decades to protect the road pavement. In recent years, the number of trucks has increased by about 40% and ...
Factors Influencing Learner Permit Duration
(MDPI, 2016-12-22)
An increasing number of countries are requiring an extended learner permit prior to independent driving. The question of when drivers begin the learner permit period, and how long they hold the permit before advancing to ...
A Novel Decentralized Game-Theoretic Adaptive Traffic Signal Controller: Large-Scale Testing
(MDPI, 2019-05-17)
This paper presents a novel de-centralized flexible phasing scheme, cycle-free, adaptive traffic signal controller using a Nash bargaining game-theoretic framework. The Nash bargaining algorithm optimizes the traffic signal ...
Teen Driving Risk and Prevention: Naturalistic Driving Research Contributions and Challenges
(MDPI, 2017-12-18)
Naturalistic driving (ND) methods may be particularly useful for research on young driver crash risk. Novices are not safe drivers initially, but tend to improve rapidly, although the pace of learning is highly variable. ...
Implementation Phase Safety System for Minimising Construction Project Waste
(MDPI, 2019-01-18)
The construction sector is a key component of a nation’s gross domestic product, but its inherent nature results in potentially dangerous conditions that affect the safety of all workers on construction projects ...
Environmental Impact of Freight Signal Priority with Connected Trucks
(MDPI, 2019-12-01)
Traffic signal priority is an operational technique employed for the smooth progression of a specific type of vehicle at signalized intersections. Transit signal priority is the most common type of traffic signal priority, ...
Use of Life Cycle Cost Analysis and Multiple Criteria Decision Aid Tools for Designing Road Vertical Profiles
(MDPI, 2019-12-12)
The current design practice for the vertical profile of roads in rolling and mountainous terrains is to follow the existing grades in order to minimize earthwork costs. This means that the only criterion considered during ...
Developing a Neural–Kalman Filtering Approach for Estimating Traffic Stream Density Using Probe Vehicle Data
(MDPI, 2019-10-07)
This paper presents a novel model for estimating the number of vehicles along signalized approaches. The proposed estimation algorithm utilizes the adaptive Kalman filter (AKF) to produce reliable traffic vehicle count ...
Virginia Connected Vehicle Test Bed System Performance (V2I System Performance)
(Connected Vehicle/Infrastructure University Transportation Center (CVI-UTC), 2016-05-01)
This project identified vehicle-to-infrastructure (V2I) communication system limitations on the Northern Virginia Connected Vehicle Test Bed. Real-world historical data were analyzed to determine wireless Dedicated Short ...
