AL-Sm: Soft road traffic Signs map for vehicular systems
نویسنده
چکیده
In this paper, we describe AL-Sm, a roadmap with traffic signs to be used in vehicular systems. AL-Sm is part of a more general system of traffic signs (TSs) management, called AL-S, which includes two sides: central map server and client vehicular system. The server allows establishing, maintaining and disseminating AL-Sm. The client localizes the vehicle in ALSm and detects TSs. In this paper, we focus on the AL-Sm establishment. AL-Sm can handle variable TSs and its update is easy, which keeps it coherent with the reality. Also, it improves the map-matching algorithm. We implemented AL-Sm easily using an Android device. Keywords—Road Traffic Signs, Roadmap, Map-Matching, Driver Assistance Systems, Autonomous vehicles

Self-Generated Road Status Maps based on Vehicular Ad Hoc Communication
The instantaneous knowledge of road course, condition and traffic situation ahead of the vehicle is of major value for all kinds of driver assistance systems. In this paper, a method for self-generating an up-to-date road status map of the local area onboard a driving vehicle is presented. A commercial digital road map is not required, since vehicles generate the map based upon satellite based ...
متن کاملRe-usability of traffic signs for inactive drivers with consideration of personal characteristics and sign features
There has been an increasing concern about inactive drivers who would easily lead to road accidents and fatalities once return to driving. This study investigated the re-usability of traffic signs for inactive drivers with consideration of driver factors and cognitive sign features. Fifty-seven Hong Kong Chinese, who possessed a full driving license but had not driven for an extended period, co...
متن کاملSimulating Vehicular Traffic Flows using the Circal System
Modern civil engineers have big problems on their hands; more cars use our road networks every year, leading to ever increasing congestion. Knowing how to change a road network to relieve congestion without spending millions of pounds doing so is a tricky business. Traffic simulators can go some way to helping the engineers know how flows will alter with changes in the network. Such changes cou...
متن کاملRoad collisions avoidance using vehicular cyber-physical systems: a taxonomy and review
Background Road traffic dynamics are complex in nature. According to Zhao (2011), road traffic demonstrates various complex systems properties like non-uniformity, non-linearity, and adaptability, hence, it can be considered as complex in nature. Manley (2014) notices that individual driver behavior and unpredictable movement choices are the key reasons of complexity in road traffic. In another...
متن کاملRoad-sign detection and tracking
In a visual driver-assistance system, road-sign detection and tracking is one of the major tasks. This study describes an approach to detecting and tracking road signs appearing in complex traffic scenes. In the detection phase, two neural networks are developed to extract color and shape features of traffic signs from the input scenes images. Traffic signs are then located in the images based ...
