Traffic Adaptive Offset-Based Preemption for Emergency Vehicles
… and evaluated a new strategy for preemption of emergency vehicles along a corridor, which is route-based and adaptive to real-time traffic conditions. The method uses dynamic offsets which are adjusted using congestion levels to provide uninterrupted preempted green signal for the emergency …

The human factors associated with responding to emergency vehicles
Emergency vehicles undertake emergency driving, using lights and sirens, to move rapidly through traffic in response to situations where life and property are at risk. For the emergency driving to be effective, other motorists need to drive in a manner that facilitates their passage. Despite laws …

A Framework and Analytical Methods for Evaluation of Preferential Treatment for Emergency and Transit Vehicles at Signalized Intersections
… are employed to provide preemption for emergency vehicles (EV) and conditional priority for transit vehicles at signalized intersections. EV preemption employs technologies and signal control strategies seeking to reduce emergency vehicle crash potential and response times. Transit …

Analysis of the characteristics of emergency vehicle operations in the Washington D.C. Region
Concerns about increased emergency vehicle response times in the Washington D.C. Region, especially during peak periods, have led to the implementation of signal preemption systems to facilitate the efficient and safe movement of emergency vehicles. However, to date only limited research has been …

Designing an Emergency Traffic Signal System (ETSS): A Case Study of an Intersection Along U.S.1, Fairfax County, Virginia
… from a local firehouse is a major problem for emergency services. Motorists often do not see flashing lights or hear sirens from the approaching emergency vehicles (EV) until emergency vehicles reach the highway entrance, often too late to take appropriate action. Many locations have installed …

Safe and Efficient Intelligent Intersection Control of Autonomous Vehicles
… Coordination Algorithm (DICA) is proposed. All vehicles in the system are Connected and Autonomous Vehicles (CAVs) and capable of wireless Vehicle-to-Intersection communication. The main advantage of DICA is that it enables us to utilize the intersection space more efficiently resulting in less …

Analysis of Crashes Involving First Responder Vehicles
… and analyze crashes involving first responder vehicles and struck-by crashes. This project concludes that approximately 1.2% of the crashes in the state of Florida involve a first responder vehicles. The findings also highlight characteristics of interest to target for more research or revise …

Effectiveness of an Emergency Vehicle Operations Course Component, Visual and Perceptual Skills: Analyzing Student Response to Searching, Identifying, Predicting, Deciding, and Executing Skills
… people killed in 2013 from accidents involving emergency vehicles. The effectiveness of an Emergency Vehicle Operations Course component of visual and perceptual skills can be measured by administering the Driver Performance Test prior to and after student participation. This study examined the …

Cooperative Automated Vehicle Movement Optimization at Uncontrolled Intersections using Distributed Multi-Agent System Modeling
… track and schedule the movement of hundreds of vehicles in real-time is highly questionable. In this research, a series of fully distributed heuristic algorithms are proposed where vehicles in the vicinity of an intersection continuously cooperate with each other to develop a schedule that …

An Analysis of Emergency Vehicle Crash Characteristics
… preventing collisions at intersections between emergency and other vehicles. The Firefighter Fatality Retrospective Study of 2002 illustrates that the second leading cause of fatal injury for firefighters is vehicle collisions. Furthermore, the involvement of an emergency vehicle in a crash can …

Privacy preservation in social media environments using big data
… be used for many beneficial purposes as well. Emergency vehicles could be more efficiently routed based on trajectory patterns, businesses could make intelligent marketing or building decisions, and users themselves could benefit by taking advantage of more conveniences. There are several …

Error discovery through human-AI collaboration
… them to not recognize rare vehicle types, like emergency vehicles. This thesis focuses on identifying errors that occur due to deficiencies in agent and human representations. In the first part, we develop an approach that uses human feedback to identify agent errors that occur due to an agent's …

An Assessment Methodology for Emergency Vehicle Traffic Signal Priority Systems
Emergency vehicle traffic signal priority systems allow emergency vehicles such as fire and emergency medical vehicles to request and receive a green traffic signal indication when approaching an intersection. Such systems have been around for a number of years, however, there is little …

Emergency vehicle siren noise: A potential for hearing loss
… fitted to South Australian Police general patrol vehicles and calculate if this noise was of an intensity to cause noise induced hearing loss. Previous studies in Western Australia and in South Australia examined noise emissions from emergency vehicle sirens for the purpose of selecting the most …

Architecture and method for providing priority charging for government authorized emergency electrical vehicles (AEEV)
… government predicts more than 1 million electric vehicles (EVs), on U.S. roadways by 2015, and these numbers will increase exponentially in the future. However, the power grid cannot furnish the charging for numerous EVs at a given time mainly because of its energy production capabilities, peak …

A Macroscopic Model for Evaluating the Impact of Emergency Vehicle Signla Preemption on Traffic
In the past, the study of Emergency Vehicle (EV) signal preemption has been mostly done using field studies. None of the simulation models that are currently commercially available have the capability to model the presence of EVs and simulate the traffic dynamics of the vehicles surrounding them. …
