This book was released on 2010-04-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Highway Traffic Safety Administration recognizes that quieter cars such as hybrid-electric vehicles in low-speed operation using their electric motors, may introduce a safety issue for pedestrians who are blind. This study documents the overall sound levels and general spectral content for a selection of hybrid-electric and internal combustion vehicles in different operating conditions, evaluates vehicle detectability for two ambient sound levels, and considers countermeasure concepts that are categorized as vehicle-based, infrastructure-based, and systems requiring vehicle-pedestrian communications. Overall sound levels for the hybrid-electric vehicles tested are lower at low speeds than for the internal combustion engine vehicles tested. There were significant differences in human subjects' response time depending on whether electric or internal combustion propulsion was used at both the lower and higher levels of ambient sound. Candidate countermeasures are discussed in terms of types of information provided (direction, vehicle speed, and rate of speed change, etc.); useful range of detection of vehicles by pedestrians, warning time, user acceptability, and barriers to implementation. This study provides baseline data on the acoustic characteristics and auditory detectability of vehicles; however, the results cannot be generalized to more complex environments, as for example when multiple target vehicles are present.

Download or read book Detection of Hybrid and Quiet Vehicles by Blind and Visually Impaired Pedestrians written by Jay M. Pliskow and published by . This book was released on 2010 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased popularity of hybrid electric vehicles has created a growing concern for the safety of blind and visually impaired pedestrians. Accident data published by the National Highway Traffic Safety Administration demonstrates a higher incident rate involving hybrid electric vehicles compared to internal combustion engine vehicles during slow speed (15 kph or less) movement. The lower sound output of hybrid electric vehicles, compared to internal combustion engine vehicles, has been reported as the reason for the high incident rates. Previous studies have focused on the overall sound pressure level of vehicles related to the ability of blind pedestrians to safely cross streets. Under more controlled conditions and lower ambient sound pressure levels than was achievable in previous research measurements were made comparing the detections of hybrid electric vehicles, internal combustion engine vehicles, and hybrid electric vehicles with added sounds. Vehicle detection tasks confirmed that when moving at slow speeds, a hybrid electric vehicle is detected, by blind pedestrians, at a closer distance and smaller safety margin when compared to traditional internal combustion vehicles. Adding additional sound to a hybrid electric vehicle resulted in detections made at a greater distance.

Download or read book Incidence of Pedestrian and Bicyclist Crashes by Hybrid Electric Passenger Vehicles written by Refaat Hanna and published by DIANE Publishing. This book was released on 2010-08 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examines the incidence rates of pedestrian and bicyclist crashes that involved hybrid electric vehicles (HEV) and compares the results to internal combustion engine (ICE) vehicles under similar circumstances. State crash files from the Nat. Highway Traffic Safety Admin.¿s State Data System were used to measure the incidence rates of pedestrian and bicyclist crashes by HEVs and to compare the incidence rate with their peer ICE vehicles. This study found that pedestrian and bicyclist crashes involving both HEVs and ICE vehicles commonly occurred on roadways, in zones with low speed limits, during daytime and in clear weather, with higher incidence rates for HEVs when compared to ICE vehicles.

This book was released on 2024-05-23 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction of sustainable road infrastructures has become an issue of concern to the international community. Road infrastructures require a large amount of non-renewable resources during the construction phase while containing abundant renewable energy resources (e.g. vehicle mechanical energy, internal thermal energy, and surface solar energy) during the operational phase. Therefore, reducing the dependence of road infrastructures on non-renewable resources, upgrading the construction and maintenance levels, improving the recycling level of infrastructure materials, and efficiently harvesting and utilizing clean energy from sustainable road infrastructures are of great significance in alleviating energy problems and promoting sustainable social development.
