The paper deals with experimental simulation measuring and the analysis of defect distribution in passenger car tire under dynamic loading. The main reason for detection of defect extension is to recognize an influence of closed air, small bubbles, separations in tire and it is mainly connected with its quality during its service in a vehicle in terms of road safety. This analysis should help constructors to solve critical conditions in tire casing, whether material selection and individual components proportions are suitable and fit or even the whole construction of tire casing is suitable. The reason for detection of internal defects in tire casing is to avoid the wear of those tires which already contain some internal defects and already recognised separations, which could propagate during the movement of vehicles. This is closely connected with the occurrence of tire destruction and the main purpose is to prevent its critical status and later vehicle crash and human life menace.

Gravel-filled arrester beds, also called safety-escape ramps or vehicle run-out areas, have long been a road-safety feature for safely stopping heavy road vehicles from running off the road. In the recent past, there has been consideration given to installing these features on highway access ramps to provide safe areas to stop passenger cars driving at highway speeds. The work presented in this article was performed to investigate the behaviour of standard-size passenger cars on gravel-filled arrester beds, with a particular focus on the achievable vehicle decelerations and the ability of the arrester beds to safely stop a passenger car coasting in an uncontrolled manner. The findings show that the achievable average decelerations are in the range of 0.3 g for coasting vehicles and up to 0.9 g when the vehicles are braking. The results prove that more research is required to quantify the influence of the gravel parameters on the achievable decelerations.

Tire/pavement contact characterization is a key point for both vehicle and road optimization in the context of road safety. LCPC laboratory has recently developed and validated an infrastructure-based measurement system to acquire the complete 6-components tire/road force tensor. In this paper; this system will be further assessed facing a testing vehicle equipped with a dynamometric wheel, in emergency braking situations, for dry or wet pavement surfaces. Regarding road management, the validated embedded system will offer the advantage of concerning a large set of vehicles, without need of any instrumentation. Measurement differences between the two systems will be discuss in terms of (intermediate) tire characteristics.

The development of a new stationary dynamometer is described, in which a passenger car is subjected to a system of forces and couples similar to that which it would experience on the roads. Speeds up to 200 km/h can be simulated. Tests on the dynamometer can be carried out in complete safety, and measurements made with an accuracy that would not be possible in tests on the road; indeed, measurements can be made on the rig which would be very difficult to make on a moving vehicle. Some of the possible applications of the dynamometer are discussed; it could, for example, be used for the study of braking, traction, steering, road holding, tyre behaviour, and deflection of headlight beams. Some of the work that has already been done is described. It is considered that dynamometers of this nature can make a great contribution to road safety.

Traffic Rules

Transportation has evolved greatly in recent years. With the modern Technologies, the automobile industry has obtained new heights with the respect to speed, efficiency and security. Despite growth and improvement in technology there has been rise in the rate of accidents. The technology used in the proposed design is embedded system. It is used to access, process, store and control the data. Now-a-day’s traffic rules are frequently violated by the drivers and over speeding occur due to bad driving behaviour. It may not be possible to view the regulatory (sign) boards placed by the Road safety Department to alert the drivers in such kind of places and there is a chance for accident. The main objective of the Project is to design and develop a new system that can effectively detect speed violations on the road, and support the driver to obey traffic rules while driving by maintaining the speed of vehicle in accordance to the speed limit prescribed for the particular zone. The proposed system gives an alert with the help of voice module and LCD. The main objective of the project is to overcome the challenges which include accidents that occur due to lack of concentration, conversing over phone while driving and the pollution emitted by the vehicles.
