The automotive industry needs sustainable seating products which offer good climate performance and superior seating comfort. The safety requirement is always a concern for current seating systems. The life of the present seating system is low and absorbs moisture over a period of time which affects seat performance (cushioning effect). Recycling is one of the major concerns as far as polyurethane (PU) is concerned. This paper presents the development of an alternative material which is eco-friendly and light in weight. Thermoplastic Polyolefin (PO) materials were tried in place PU for many good reasons. It is closed cell foam which has better tear and abrasion resistance. It doesn't absorb water and has excellent weathering resistance. Also it has a better cushioning effect and available in various colours. Because of superior tear resistance, it is possible to eliminate upholstery and would reduce system level cost.

India has the highest number of road accidents in the world. With over 130,000 deaths annually, the country has overtaken China and now has the worst road traffic accident rate worldwide. This has been revealed by the World Health Organization (WHO) in its Global Status Report on Road Safety pointing to speeding as the main contributing factor. This paper studies and details all the approaches for the reduction of accidents adopted by various countries and especially the necessity of speed governors in Indian vehicles and the role of the same in reduction in accidents with other benefits of speed governors with regard to fuel efficiency, noise & pollutant emissions both in Indian and International aspects.

Overloading is not only a problem for larger goods vehicles, it is equally a problem for smaller vehicles, such as vans, cars and passenger carrying vehicles. Reports indicate that nearly 70% of all traffic on national highways comprise of cargo vehicles while 22% of cargo vehicles are involved in road accidents. Overloading increases the risk of traffic accidents and causes excessive wear and damage to roads, bridges, pavements etc. This paper specifies in detail the existing Indian Legislation on Overloading, different methods of monitoring, Vehicle Overload Control in other countries and India recommendations to curb Overloading of vehicles.

Evolution of Bus Design in India

Buses have been main means of mass transport in organized as well as unorganized sectors in India. Though the art and science of Chassis Designing had been practiced and matured by all Indian OEMs, Body design had long not been accorded high priority by them. Till 1989, there was no comprehensive set of rules enforced. Bus designs were developed with scant regard for safety and emission. OEMs sold their products in the form of drive away chassis and the Body Design & Body Building was largely left to Body Builders, many of whom employed poor design, build and quality control practices. Spurious materials, parts, non-uniform construction resulted in number of accidents and many of them were fatal. Central Motor Vehicle Rules (CMVR) kicked-in 1st July 1989. With roll out of CMVR, various safety related features like entry/exit door, emergency exits, window frames, their locations, dimensions and designs were defined.
