2.Accelerometer based accident detection System
An accident is a deviation from expected behavior of event that adversely affects the property, living body or persons and the environment. Security in vehicle to vehicle communication or travelling is primary concern for everyone. The work presented in this article documents the designing of an accident detection system. The accident detection system design informs the police control room or any other emergency calling system about the accident.
An accelerometer sensor has been used to detect abrupt change in g-forces in the vehicle due to accident. When the range of g- forces comes under the accident severity, then the microcontroller activates the GSM modem to send pre-stored SMS to a predefined phone number. Also a buzzer is switched on. The product design was tested in various conditions. The test result confirms the stability and reliability of the system
3.Implementation OF Real Time Passenger Information System Using GPRS (RTPIS)
RTPIS provides travel information to passengers and tourists enabling them to make informed decisions about modes, routes and departure times. The RTPIS framework can be broadly divided into two contexts: (1)Pre-trip context and (2) On-trip context. Pre-trip context:-The former provides information like timings, fares and routes well before the commencement of travel, through the Internet or the Short Messaging Service (SMS). The Ontrip context: - provides information like location and places of interest (POI) while on the move. This is achieved using on-board and at-stop terminals (displays and audio announcement units).
4.Advanced Rural Transportation Systems (ARTS)
Advanced Rural Transportation Systems (ARTS) provide information about remote road and other transportation systems.

10.Approach lightening system/pilot controlled lightning at airport runway for energy conservation
Pilot Controlled Lighting (PCL), also known as Aircraft Radio Control of Aerodrome Lighting (ARCAL) or Pilot Activated Lighting (PAL), is a system which allows aircraft pilots to control the lighting of an airport or airfield's approach lights, runway edge lights, and taxiways via radio. At some airfields, the aerodrome beacon may also be ARCAL controlled. ARCAL is most common Anton or little-used airfields where it is neither economical to light the runways all night, nor to provide staff to turn the runway lighting on and off.
It enables pilots to control the lighting only when required, saving electricity and reducing light pollution. The ARCAL frequency for most aerodromes is usually the same as the UNICOM/CTAF frequency, although in some rare cases, a second ARCAL frequency may be designated to control the lighting for a second runway separately (an example of this is runway 01/19 at the airport in Sydney, NS). To activate the lights, the pilot clicks the radio transmit switch on the ARCAL frequency a certain number of times within a specified number of seconds.
There are two type of ARCAL systems, type J and type K. When either type of system is activated, a 15-minute countdown starts, after which the lights turn off. While the lights are on, whenever a lighting command is issued, whether it changes the lighting intensity or not, the 15-minute countdown is reset. At some airfields, the lights may flash once to warn pilots that the lights are about to go off, before turning off two minutes later.
When using ARCAL, it is strongly recommended that aircraft on final approach to the airfield issue a fresh lighting command, even if the lights are already on (especially if the lights were activated by another aircraft). This is so that the lighting does not turn off at a critical moment (such as when crossing the runway threshold).
11.Design and control of Segway
The purpose of the project was to design and build a 1/5th scale Segway cart. The cart was modeled after a two wheeled transportation device that uses sophisticated electronics to balance. The cart was designed to follow a line as fast as possible while still keeping a load balanced atop. The cart was limited to several maximums; a height of 6 inches, a mass of 1-kg, wheel diameters between 0.5 and 6 inches, and removable handlebars from 7-9 inches.
The cart also had to support a cylindrical mass with specifications of, a mass up to 2-kg, and a diameter of up to 6-inch. The cart was designed to rock on its wheels over a range of 60 degrees forwards and backwards as well as to follow a black electrical tape line on a light colored floor. The cart was expected to be self-contained including the power source. With the above design constraints, the cart was then designed to be lightweight, structurally strong enough, inexpensive, and to follow the specified path.
The cart was constructed of hollow aluminum tubing, which made up the frame. The tubing was soldered together. The cart used a spinning hanging mass attached to a potentiometer to sense the angle of tilt. By measuring the change in voltage in the potentiometer as the cart tilted, the balancing of the cart was regulated. Photo sensors were implemented for detecting the black electrical tape and to start the cart in motion
12.Electronic Toll Collection (ETC)
The Electronic Toll Collection (ETC) is designed to determine if a car is registered in a toll payment program,alert enforcers of toll payment violations, and debit the participating account.

This is so that the lighting does not turn off at a critical moment (such as when crossing the runway threshold).
• The purpose of the project was to design and build a system that can turn of and turn on relays of light while the Airplane approaches and leaves the runway. The lights will be turning on and off on the movement of airplane. Hence when no airplane is there lights will be off only.
• This will be based on RF (radio frequency) and through turn on the relay of lights on runway. As soon as the light is gone it will turn off the relay of light at the runways.

19.Vehicle-to-Vehicle cooperative communications
In this paper, we provide a measure of reliable vehicle-to-vehicle communication, which is referred to quality-supporting duration (QSD). QSD is defined as a maximum allowable time that ensures a given outage probability target. When designing frame length or feedback interval for road safety systems, QSD can be used as a reference time interval during which the reliable communication is possible. We investigate QSD in cooperative communication environments.
Both a single-relay case and a multiple-relay case are considered. Each vehicle is assumed to have a random velocity that is uniformly distributed and it is unchanged during the time span considered in the paper. But the distance between vehicles are time-varying since the speeds are different form vehicle to vehicle. The outage probability of vehicle-to-vehicle networks environment hence depends on the time-varying distance and is also time-varying.
We first express speed-average outage probability. With numerical investigation, we show QSD against the initial distance, the speed range of the vehicles and the number of cooperative relays, respectively. QSD decreases when the initial distance increases or the speed range increases. But QSD increases when the number of cooperative relays increases.

25.Participatory sensing based real-time public transport information service
Modern cities continuously struggle with infrastructural problems especially when the population is massively growing. One affected area is public transportation. In default of offering convenient and reliable service the passengers tend to consider other transport alternatives. However, even a relatively simple functional enhancement, such as providing real-time timetable information, requires considerable investment and effort following traditional means, e.g. deploying sensors and building a background communication and processing infrastructure.
Using the power of crowd to gather the required data, share information and send feedback is a viable and cost effective alternative. In this demonstration, we present Traffic Info, our prototype smart phone application to implement a participatory sensing based live public transport information service. TrafficInfo visualizes the actual position of public transport vehicles with live updates on a map, and gives support to crowd sourced data collection and passenger feedback.

This project implements a high speed data acquisition system using Mega32 microcontrollers and a Controller Area Network (CAN). Recording data is essential to testing and developing a racecar. Recording what each sensor is doing can tell an engineering how the car is performing, and most importantly, how to make it faster. A well outfitted car can have many sensors, with Formula One cars having well over 100 sensors.
If taking the derivative of the data a very high sampling rate is required to give useful data, at least 500 Hz. Our system uses multiple transmitter nodes to acquire data from sensors and transmit the data in packets over a CAN bus. Each transmitter consists of a ARM7 microcontroller, an external Analog-to-Digital converter, a CAN controller and a CAN transceiver.The CAN packets are received by a single receiver node and stored to a Secure Digital (SD) card.
The receiver node consists of a ARM7, a CAN controller, a CAN transceiver, and a SD card. The goal of the project was to create a system which can record 10 bit ADC channels recorded by ARM7 and transmitted over the CAN bus. In addition, the system should be expandable to accept CAN packets sent from other modules, such as an ECM or a standalone O2 unit. 500 Hz on the 32 AD channels was set as a goal for sampling frequency.
