Development of Emergency Vehicle Approaching Alert System (EVAAS)

International Centre For Automotive Tech.-Bhavna Bhavna
  • Technical Paper
  • 2019-28-2465
To be published on 2019-11-21 by SAE International in United States
This paper discusses the need for Emergency Vehicle Approaching Alert System (EVAAS) and building of EVAAS components for OTT (over- the-top content), and Media providers. According to a study by the Indian Journal of Surgery in 2006, 80 per cent of road accident victims in India do not receive any emergency medical care (Ambulance) within this ‘golden hour - the first hour after a traumatic injury, when emergency treatment is most likely to be successful.’ Due to increasing population and constructions of Roads and Buildings, Emergency Vehicles are not able to reach the desired location. Hence, there is a need of an Emergency Vehicle Approaching Alert System (EVAAS) in INDIA.

To be published on 2019-11-21 by SAE International in United States
In this paper, we will detect and track vehicles on a video stream and count those going through a defined line and to ultimately give an idea of what the real-time on street situation is across the road network. Our major objective is to optimize the delay in transit of vehicles in odd hours of the day. It uses YOLO object detection technique to detect objects on each of the video frames And SORT (Simple Online and Realtime Tracking algorithm) to track those objects over different frames. Once the objects are detected and tracked over different frames a simple mathematical calculation is applied to count the intersections between the vehicles previous and current frame positions with a defined line. At present, the traffic control systems in India, lack intelligence and act as an open-loop control system, with no feedback or sensing network. Present technologies use Inductive loops and sensors to detect the number of vehicles passing by. This is a very inefficient and expensive way to make traffic lights adaptive. Using a simple CCTV camera…
 

Vision-Based Techniques for Identifying Emergency Vehicles

Texas A&M University-Abhishek Nayak, Swaminathan Gopalswamy, Sivakumar Rathinam
Published 2019-04-02 by SAE International in United States
This paper discusses different computer vision techniques investigated by the authors for identifying Emergency Vehicles (EV). Two independent EV identification frameworks were investigated: (1) A one-stage framework where an object detection algorithm is trained on a custom dataset to detect EVs, (2) A two-stage framework where an object classification algorithm is implemented in series with an object detection pipeline to classify vehicles into EVs and non-EVs. A comparative study is conducted for different multi-spectral feature vectors of the image, against several classification models implemented in framework 2. Additionally, a user-defined feature vector is defined and its performance is compared against the other feature vectors. Classification outputs from each of the frameworks are compared to the ground truth, and results are quantitatively listed to conclude upon the ideal decision rule. As maintaining the speed of data output is the priority throughout our development, a computationally inexpensive object tracking algorithm is selected to accurately track EV between image frames. This vision-based EV detection scheme fused with data from other sensors on our autonomous vehicle shall be used…

Impacts of Flashing Emergency Lights and Vehicle-Mounted Illumination on Driver Visibility and Glare

Rensselaer Polytechnic Institute-John Bullough, Nicholas Skinner, Mark Rea
Published 2019-04-02 by SAE International in United States
Flashing emergency lights on police cars, fire trucks, and ambulances need to be bright enough to alert otherwise unaware drivers about their presence on and near the roadway. Anecdotal evidence suggests that public safety agencies select emergency lighting systems with red or blue flashing lights based on their apparent brightness, with brighter lights judged as "better." With the advent of light emitting diodes (LEDs), emergency flashing lights are brighter and produce more highly saturated colors, thereby causing greater discomfort and disability glare. As a result, first response workers are at higher risk for being injured or killed in vehicle crashes because approaching drivers cannot see them. In the present study, participants viewed red and blue flashing lights on a scale model police vehicle, conforming to present recommended practices for emergency lights. Lights varied in intensity and optical power (intensity × duration). Participants were asked to view the scale model police vehicle and identify whether a police officer figure was standing beside the vehicle. In some trials, white LED sources were energized, providing low-level illumination on…

Applicable Aircraft Integrated Vehicle Health Management (IVHM) Regulations, Policy, and Guidance

HM-1 Integrated Vehicle Health Management Committee
  • Aerospace Standard
  • AIR6900
  • Current
Published 2019-01-14 by SAE International in United States
This AIR lists and describes a collection of regulations, policy, and guidance documents applicable to design approval applicants, aircraft operating certificate holders, and maintenance repair and overhaul (MRO) organizations. The aircraft industry should consider these rules when installing IVHM technology for use in aircraft maintenance. This is a starting basis and should not be considered as complete when certification of an IVHM system is expected. The AIR’s objectives are: 1 To set the foundation for aircraft certification applicants seeking to design IVHM solutions as part of the type certificate (TC), supplemental type certificate (STC), amended TC, or amended STC activities; and 2 To set the foundation for aircraft operating certificate holders to engage with regulators to get authorization for using IVHM applications as part of an aircraft maintenance program. NOTE: This AIR’s scope is limited to the United States (U.S.) Federal Aviation Administration (FAA) information only in this version, but future revisions intend to include other regulator input.
