    Low cost black box for cars
    (IEEE Computer Society, 2013) Patil, C.; Marathe, Y.; Amoghimath, K.; Sumam David, S.
    Automotive electronics plays a significant role in the automobile industry and provides luxurious features and more importantly addresses the safety and security concerns. The work presented in this paper aims at providing a cost effective solution to the design and development of an event data recorder which has been basically adopted from the aviation sector considering the need and the correlated benefits. The paper presents an integrated design of the black box with the basic features of the data recorder which could be very useful for domestic vehicles and at the same time it also hosts several additional features that could assist in mitigating the number of accidents, or at bare minimum, will serve as an analysis tool to prevent future accidents by analyzing the previous accidents. The black box also provides automatic accident notification system which helps in informing the nearest hospital and the traffic authority by providing not only the coordinates of the accident but also the exact physical address for immediate medical attention which can save numerous lives every day. The black box also hosts several other features like CAN compatibility, attractive user console and advanced web tracking anytime and from anywhere. Thus the overall cost is highly optimized by integrating such multiple features. © 2013 IEEE.

    Factors Influencing Post-encroachment Time of Road Crossing Pedestrians Near Bus Stops Located on Mid-Block Sections
    (Springer Science and Business Media Deutschland GmbH, 2024) Ajaykrishnan, M.J.; Sethulakshmi, G.; Mohan, M.
    The increase in road traffic poses a significant threat to vulnerable road users, heightening the demand for their safety. According to the recent Road Accidents Statistics (MoRTH, 2020), out of the total road accidents reported in 2020, 15.8% involved pedestrians, and 65.1% occurred on straight road sections. This highlights the difficulty and lack of safety for pedestrians. Lack of visibility is the major cause of most accidents, and in the case of bus stops, parked buses affect the visibility of crossing pedestrians. In this study, traffic safety of crossing pedestrians is analysed using the proactive approach, which identifies an observable non-crash event that could have led to a conflict. Post-Encroachment Time (PET) is the most popular time-based measure that is the least time-consuming for accurate estimation of surrogate safety. This paper focuses on determining factors which affect PET of pedestrian crossings at mid-block sections with designated or undesignated bus stops. Videographic surveys were conducted at two mid-block sections with bus stops in Kerala, where accidents to pedestrians are frequent. Kinovea software was used to extract data from the recorded video samples, and IBM SPSS software was used to outline the factors influencing PET. The study found PET of crossing pedestrians to have a high positive correlation with the time taken for the vehicle to approach the crossing pedestrian, while other factors like evasive action and compliance behaviour were negatively correlated. The study proposed a model that will enable the easy computation of PET values of crossing pedestrians. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

    Situation awareness of deep mining environment using raspberry pi
    (American Scientific Publishers order@aspbs.com, 2019) Ramesh, B.; Vittal, K.
    The signal from sensor network helps to check the environmental parameters. Sensors have been employed in many fields such as coal mine safety monitoring, industrial monitoring, and also in healthcare monitoring. In this paper, sensor data collection using raspberry pi is studied. Use of analog to digital converter MCP3008 for connecting analog signal to raspberry pi is also studied. The study is mainly to emphasize the use of different sensors and electronic devices to monitor the parameters in deep mining environment. © © 2019 American Scientific Publishers All rights reserved.
