Right-turn Traffic Volume Adjustment in Traffic Signal Warrant Analysis
… was based on the research project, Right-Turn Traffic Volume Adjustment in Traffic Signal Warrants, sponsored by the Nevada Department of Transportation (NDOT). Right-turn traffic does not affect intersection performance in the same magnitude as through or left-turn traffic. Therefore, it is …

Artificial Intelligence and Spatial Modeling to Estimate Traffic Volume Measures on Local Roadways
… techniques to estimate Annual Average Daily Traffic (AADT) on local roadways, which are often data-scarce yet crucial for transportation planning and infrastructure development. Traditional traffic monitoring methods, such as permanent traffic count stations and short-term manual counts, are …

Stochastic numerical approximation approaches for estimation of traffic volume under travel demand uncertainties
… assignment does not account for uncertainties in traffic demands. These point-estimate based solutions often results in large differences between forecasted and actual traffic volumes thereby imposing huge financial burdens upon development agencies. In this work, stochastic treatment has been …

Methodology to Assess Traffic Signal Transition Strategies Employed to Exit Preemption Control
… vehicles to preempt the normal operation of traffic signals has the potential to improve the safety and efficiency of both the requesting vehicle and all of the other vehicles. Little is known about which strategy is the most effective to exit from preemption control and transition back to …

Machine Learning–Based Detection of Network Failures in Core Network Cellular Data
… complexity of mobile networks and the large volume of traffic data generated by multiple network elements make it difficult for Mobile Network Operators (MNOs) to accurately identify operational irregularities and reliably distinguish true network failures from normal network traffic. This …

Design and Performance of Managed Lanes in a Mixed Driver-Operated and Autonomous Vehicle Environment
… since their strategies can be adjusted based on traffic demand. Therefore, ML strategies and envelope designs may need reassessment. This study optimizes ML design strategies and evaluates the impact of these strategies on freeway performance at various AV adoption rates (i.e., 25%, 50%, and 75%) …

Traffic Conflict Analysis Under Fog Conditions Using Computer Simulation
… conditions, which has a significant impact on traffic safety. Such condition reduces the road's visibility and consequently can affect drivers' vision, perception, and judgments. The statistical data shows that many crashes are directly or indirectly caused by the low-visibility weather …

Developing pavement preservation and mitigation strategies using Pavement ME design guide for Rhode Island DOT
… and existing hot mix asphalt (HMA) layers, traffic volume, binder grade of the surface HMA layer and the base layer modulus. The surface HMA layer thickness and traffic volume were significant at 95% confidence level for both types of rutting and terminal IRI. The existing HMA layer …

Car Following and Dynamic Dilemma Zone Model for Determining Gate Operation Times Based on Driver Behavior at Highway-Rail Intersections
… gate operation parameters applicable to higher traffic volume conditions where four quadrant gate design criteria have not been considered.

A NOVEL CROWD SENSING FRAMEWORK FOR URBAN COMPUTING APPLICATIONS
… of the surrounding environment, such as traffic conditions, broken public utilities, gas prices, weather conditions and air quality. Despite the large amount of data collected from the crowd sensing applications, there are several challenges which prevent us from obtaining useful …

Development of Arrival-Type-Based Uniform Delay Models for Signalized Intersections
… of vehicles in platoon, (2) Are sensitive to traffic volume inside platoon, and (3) because a distinct delay model was deduced for each arrival type, the need for applying delay adjustment factors was eliminated. Furthermore, the input parameters required to use the proposed models are the …

Volume-based Probabilistic Approaches to Determining When to Turn on and off Signal Coordination Plans
Traffic signal coordination is an engineering tool used to enhance the quality of traffic flow, increase traffic throughput, reduce travel time and delay, and reduce number of stops by providing good progression along major arterials. While vehicles on major arterials benefit from signal …

Development of safety performance functions and a GIS based spatial analysis of collision data for the City of Saskatoon
… frequency at a particular location with traffic volume and roadway characteristics. The purpose of this research is to develop a series of locally derived SPFs for the City of Saskatoon to allow engineers to estimate the expected number of collisions for the purpose of evaluating new …

Development of a methodology for measuring delay-based passenger car equivalent for heavy vehicles at signalized intersections
… The constant PCE value, which is independent of traffic volume and percentage of heavy vehicles, is inappropriate in capacity analysis when delay is considered. Among other analysis procedures, the 1985 Highway Capacity Manual (HCM) and the 1994 HCM were found to be deficient for estimating the …

A Comparison of Water Main Failure Prediction Models in San Luis Obispo, CA
… are in highly corrosive soil and average daily traffic volume data instead of using street classifications. The statistically simple model only uses the pipe age and material for probability of failure. The age-based model relies purely on the age of the pipe to determine its probability of …

Essays on Urban Economics
… methodologies, I examine the effects of traffic pricing policies and rider-hailing services on traffic and air quality. Chapter 1 investigates the traffic and environmental impact of traffic pricing policy. This paper estimates the heterogeneous effect of the London congestion charging …

Lead, cadmium, nickel and zinc concentrations in soil and vegetation associated with highways of different traffic densities
… was collected along four highways of different traffic volumes, at varying distances from the road, and at two control areas. Four sampling periods were conducted throughout the course of a year from August, 1976 to June, 1977. Soil and vegetation samples were tested for concentrations of lead, …
