Dancing manhole covers are an intriguing and curious phenomenon but extremely dangerous for road vehicles as well as pedestrians. They are reported worldwide after heavy rainfall in urban environment. Stormwater systems are overloaded with running water containing large entrapped air pockets for which manholes form an escape route. However, heavy lids cover the manholes and they are supposed not to move. An attempt is made to understand the physics behind dancing manhole covers by means of simple spring-mass-ashpot modeling. The ingredients are liquid slugs, air pockets, and fluid-structure interaction.

Design, analysis and experimental study of a novel side thorax impactor to be used in pedestrian protection tests for flat front vehicles Saraç Karadeniz, Sevgi; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2021-10) Pedestrian protection is crucial and the vehicle manufacturers put more and more effort to make vehicles safer for pedestrians in case of pedestrian involved accidents. Injuries and fatalities are very frequent and severe in pedestrian involved accidents because the pedestrians are much more vulnerable when compared to the vehicle occupants as they do not have any protection like airbags or seatbelts. The current pedestrian protection regulations focus on the tests of bonnet type passenger cars for the head...
Evaluation of pedestrian safety around bus stops using geographic information systems Yüksekol, İrem; Tüydeş Yaman, Hediye; Department of Civil Engineering (2012) Pedestrians are the most vulnerable road users in terms of traffic safety. Public transit users mostly have a pedestrian trip before and/or after the transit one. Thus, pedestrian activity is produced at transit stops naturally. The main focus of this study is pedestrian safety problems around transit stops, more specifically bus stops. The proposed methodology first includes Geographic Information Systems (GIS) analyses of the pedestrian safety along the study corridors and around bus stops on them; this e...
Investigating Noung Male and Female Road Users' Behaviour as Pedestrians and Drivers ÖZTÜRK, İBRAHİM; Öz, Bahar (2021-01-01) Young road users constitute one of the most vulnerable groups in terms of experiencing road traffic accidents as either drivers or pedestrians. Pedestrian and driver behaviours are important predictors of the road users' safety. The present study mainly aims to investigate the relationship between behaviours of young male and female road users as drivers and pedestrians. A total number of 573 young road users (316 male, 257 female) aged from 19 to 28 (M = 22.2, SD = 1.77) participated in the present study. ...
Vibration Exposure of Front Seat Car Passengers Erol, Tuğra; Birlik, Gülin; Sezgin, Önder; Tarman, Işık Hakan (null; 2004-09-17) Vibration in the vehicle environment has long been investigated considering the driver's exposure. However not only drivers but also the front seat car passengers are exposed to considerable amount of vibration. In order to investigate the phenomenon, this research consisted of three stages. In the first stage of the study, model analysis has been carried out. Based on the results it has been suggested that increased damping in the lumbar area in contact with the backrest can decrease the vibration transmis...
Pedestrian violations: Reasoned or social reactive? Comparing theory of planned behavior and prototype willingness model DEMİR, BAŞAR; Özkan, Türker; Demir, Sila (2019-01-01) Pedestrians hold high responsibility in accidents because of their unsafe traffic behaviors. Pedestrian violations are an important traffic safety problem, especially in low and middle-income countries. The problem would be better understood and solved by theory-based research on pedestrian violations. The theory of planned behavior (TPB) and the prototype willingness model (PWM) are two leading decision-making frameworks that are applied to a wide range of behaviors. These theories address the reasoned and...
