Modeling A Consortium-Based Distributed Ledger Network With Applications For Intelligent Transportation Infrastructure, Luis A. Cintron

Theses and Dissertations

Emerging distributed-ledger networks are changing the landscape for environments of low trust among participating entities. Implementing such technologies in transportation infrastructure communications and operations would enable, in a secure fashion, decentralized collaboration among entities who do not fully trust each other. This work models a transportation records and events data collection system enabled by a Hyperledger Fabric blockchain network and simulated using a transportation environment modeling tool. A distributed vehicle records management use case is shown with the capability to detect and prevent unauthorized vehicle odometer tampering.

Development Of System-Based Methodology To Support Ramp Metering Deployment Decisions, Homa Fartash

FIU Electronic Theses and Dissertations

Ramp metering is an effective management strategy, which helps to keep traffic density below the critical value, preventing breakdowns and thus maintaining the full capacity of the freeway. Warrants for ramp metering installation have been developed by a number of states around the nation. These warrants are generally simple and are based on the traffic, geometry, and safety conditions in the immediate vicinity of each ramp (local conditions). However, advanced applications of ramp metering utilize system-based metering algorithms that involve metering a number of on-ramps to address system bottleneck locations. These algorithms have been proven to perform better compared to …

Using Connected Vehicle Technology To Implement A Pay For Priority System At Signalized Intersections, Melissa Gende

All Theses

This research evaluated a mixed vehicle environment that included connected and non-connected vehicles in which connected vehicles (CV) were allowed to pay a small fee to request priority at a signalized intersection, similar to a transit signal priority system. Connected vehicles with signal priority were simulated with penetration levels ranging from 10% to 100% as well as with various priority directions (all directions, major street movements in both directions, and major street movements in the direction of highest flow) being allowed to request priority. These scenarios were compared to optimized signal timings to determine the effectiveness of the technology in …

Connected Vehicle Supported Electric Vehicle Charging Operations And Related Infrastructure Issues, Jennifer Johnson

Jennifer Johnson

Due to the tremendous political, economic and environmental pressures the transportation sector is facing, the United States finds itself devoting more energy to innovative solutions like electric vehicle (EV) technologies. The first objective of this study was to analyze how utilizing real-time information dissemination transferring capabilities to vehicles, as envisioned in the 'connected vehicle' system, could effectively facilitate the EV charging process at fast-charging stations. By simulating a traffic network of EVs in Matlab, it was found that the total time due to the battery charging process could be optimized for EVs that were able to use connected vehicle communications. …

How Rapidly Should Developing Countries Implement Intelligent Transportation Systems (Its) To Solve The Growing Urban Traffic Congestion Problem?, Mandar Khanal

Civil Engineering Faculty Publications and Presentations

Many newly developing countries are growing rapidly. One example is India, currently the second most populous country in the world. According to the Indian Ministry of Urban Development, from 1981 to 2001, the population in six major Indian cities increased twofold while motor vehicles increased eightfold. Such rapid growth in vehicles without a comparable growth in transportation infrastructure leads to increasing traffic congestion. Cities in India are already considered congested today, and are going to be even more congested in the coming years since the rate of urbanization in India in 2006 was only 29% and is expected to grow …

Archived Data Management System In Kentucky, Mei Chen, Jingxin Xia

Kentucky Transportation Center Research Report

Archived Data User Service (ADUS) was added to the national ITS architecture in 1999 to enable multiple uses for ITS-generated data. In Kentucky, ARTIMIS and TRIMARC are collecting volume, speed, occupancy, length-based classification, and incident data on a continuous basis. This study developed the Kentucky Archived Data Management System (ADMS) to archive and disseminate data collected by sensors in ARTIMIS and TRIMARC systems. This system is designed to be the prototype of ITS data clearinghouse in Kentucky.

The Kentucky ADMS operates on a web server that allows users to retrieve traffic data (i.e., volume, speed, lane occupancy) in 15 minute …

Sensor-Based Computing Techniques For Real-Time Traffic Evacuation Management, Georgiana Hamza-Lup

Electronic Theses and Dissertations

The threat of terrorist incidents is higher than ever before and devastating acts, such as the terrorist attacks on the World Trade Center and the Pentagon, have left many concerns about the possibility of future incidents and their potential impact. Unlike some natural disasters that can be anticipated, terrorist attacks are sudden and unexpected. Even if sometimes we do have partial information about a possible attack, it is generally not known exactly where, when, or how an attack will occur. This lack of information posses great challenges on those responsible for security, specifically, on their ability to respond fast, whenever …

Implementation Strategies For Real-Time Traffic Safety Improvements On Urban Freeways, Jeremy Harvey Dilmore

Electronic Theses and Dissertations

This research evaluates Intelligent Transportation System (ITS) implementation strategies to improve the safety of a freeway once a potential of a crash is detected. Among these strategies are Variable Speed Limit (VSL) and ramp metering. VSL are ITS devices that are commonly used to calm traffic in an attempt to relieve congestion and enhance throughput. With proper use, VSL can be more cost effective than adding more lanes. In addition to maximizing the capacity of a roadway, a different aspect of VSL can be realized by the potential of improving traffic safety. Through the use of multiple microscopic traffic simulations, …
