Abstract :
In this project, a prototype of the small metro capable of showing the station on the LCD display with various other facilities is designed. This metro is run on the DC gear motor. Metro train is auto stop on 5 different stations and reverses automatically with Voice Announcement facility. The DC motor is attached with the gear inside to reduce the speed of the vehicle. For controlling the direction of the motor we use H bridge circuit. With the help of H bridge it is possible to control the direction of motor on either side. ....etc

INTRODUCTION
The national commission on urbanization (NCU) has noted that “urban transportationis the single most important component instrumental in shaping urban development & urbanliving” In the next millennium, almost all the metropolitan cities are a serious threats ofenvironmental pollution, traffic congestion, parking problem, population burden etc.Massrapid transit systems (MRTS) are rail based urban transit systems and the only mode of
public transportation capable of carrying large number of people in ....etc

METRO TRAIN PROTOTYPE

ABSTRACT
This project is designed so that students can understand the technology used in the now a day’s driver less metro train which is used in most of the developed countries like Germany, France, and Japan etc. These trains are equipped with the CPU, which control the train. The train is programmed for the specific path. Every station on the path is defined; stoppage timing of the train and distance between the two stations is predefined.

INTELLIGENT METRO TRAIN
OBJECTIVE:
In this project we have to announce the place in LCD.The train we have to stop automatically 2 mints in the stop
BLOCK DIAGRAMS:
There is RF transmitter (Tx) in the train and their is a RF receiver (Rx)
Connected to PIC 16F877A micro controller to control the movement of DC motor that’s is movement of train depends on TX signal the display will come in LCD.
Hardware Software requirement:
1.PIC
2.16X2 LCd
3.7805
4.Tx module
5.Rx module
6.Train model
....etc

RUBBER TYRED METRO


INTRODUCTION
A Rubber-tyred metro is a form of rapid transit system that uses a mix of road and rail technology.
In this the vehicles have wheels with rubber tyres like a bus, but using a set of two parallel concrete or corrugated steel rollways, each with the width of a tyre.
The vehicles have wheels with rubber tyres which run inside a guide way for traction, as well as traditional railway steel wheels with flanges on steel tracks for guidance.

HISTORY

INTELLIGENT TRAFFIC MANAGEMENT SYSTEM FOR METRO CITIES


Introduction

The project “intelligent traffic management system for metro cites”, is based on the microcontroller which will provide the controlling of the traffic depending upon the density.
According to the signaling i.e. continuity between the IR transmitter and IR receiver the
Timing of the green, red ,orange lights will be glown for the particular time depending upon the density.
The micro controller will monitor ....etc
