A warning message is sent to the authorized user via GSM. The advantage of this system is proper detection and faster response time leading to faster diffusion of the situation, compared with the manual methods. To give intimation to RTO office, RTO can control the speed of vehicle through remote PC Keywords: Gas detecting sensors,GSM modem, Picmicrocontroller,Ultrasonic distance sensor ________________________________________________________________________________________________________ I. INTRODUCTION It is common that on a typical day in modern society, a person has to face a considerable number of problems with current transportation systems, such as traffic congestion and parking difficulties, longer commuting times, higher levels of CO2 emissions, and an increased number of accidents, among others. Consequently, modern society could face serious problems with traffic congestions. Finally, even though the economic costs of transportation are significant, the human cost resulting from vehicular accidents is high. According to the Commission for Global Road Safety, road crashes kill at least 1.3 million people each year and injure 50 million, with 90 percent of these road casualties occurring in low and middle-income countries. These motor vehicles contribute to over 30% of the hazardous gases that are released into the atmosphere. The embedded system is used inside a vehicle cabin such that the presence or leakage of toxic gases can be detected by the gas sensors and proper precautions can be taken to avoid the driver from getting fatigue or drowsiness.

Emission Measurement Equipment The Axion system, which is a portable emission measurement system, was used to measure the emissions and fuel consumption of the vehicles in real operating conditions. In each mobile test, the Axion equipment was first setup onboard the vehicle, a short version of the stationary test was conducted, and a 10-min trial run was conducted to assure that collection of data was occurring during vehicle operations. Then, the vehicle was operated for three 30-min segments on its normal mowing route. During the route, the equipment was visually monitored from a following vehicle, whereas the location, speed, and operation of the mowing vehicles were measured using an onboard X-driven video camera/GPS unit and a Sky TRX GPS unit. The Axion system is an updated version of the Montana System produced by Clean Air Technology International and used by Frey et al. in a number of onboard real-world emission measurement studies including off- road graders and construction equipment. The Axion system provides second-by-second measurements of four gaseous emissions: hydrocarbons(HCs), carbon monoxide (CO), nitrogen oxide (NO),carbon dioxide (CO2), and a semi-quantitative measure of PM. The Axion system measures NO concentration using an electrochemical cell, and reports the mass emission rates by using the molecular weight of NO2. The Axion reports the mass emission rates in terms of equivalent NO2 mass because this is the convention for measuring total NOx (NO2 + NO) emissions using chemi luminescence.
