INTELLIGENT METROBUS STOPS
Systems Development Life Cycle

STAGE 1: OPERATIONAL– NEED DETERMINATION
* Reduce the traffic
The metrobus system, which IETT has effectuated in order to reduce the traffic density at the main arteries of traffic in Istanbul and to provide quick and comfortable transportation, primarily started to serve at Topkapi-Avcilar route. * To encourage more use of public transport 

The metrobus system, which reduced the Access time of Topkapi-Avcilar to 22 minutes, it was 67 minutes previously, will be extended to Beylikduzu at the European side of Istanbul and to Kozyatagi the Anatolian side of Istanbul. One bus can carry  600.000/day. The number of people that typically travel in a car - making bus travel greener and reducing congestion on our roads. Metrobus improves reliability and more people will be encouraged to leave the car at home and use the bus more often. The metrobus system, which displays further development potential than other express lines; whose investment and operation costs are absolutely lower than other railways; whose establishment is completed in a shorter time relatively, has primarily reduced the traveling period, providing time saving. Since the vehicles move on their specific road, the accident rate and risk reduces. High-tech devices within the system provide a safer and more comfortable travel. By means of its environment-friendly engines, the emission rates reduce drastically and the hybrid engine provides approximately 40% fuel savings Its drawing near alongside the stop facilitates the disabled travelers to get on the metrobus. Operational Capabilities

* Intelligent Metrobus Signs provide;
* Real time travel information at high-use bus stops
* Timetables, route maps and local area maps
* Need minimum maintenance and have a long service life
* No need excavation, easy fitting
* Promoting more people to use public transit
* Audiable signange fort he visually impaired
* Save %75 energy more than traditional stops
* Solar-powered system, friendly to environment
* Can be used as a lighting and 220 Volt AC power supply in case of emergency or natural disaster * Can call emergency with the emergency/panic button
* Intelligent metrobus sign system should be designed to withstand malicious use (A push button also triggers an audible message of the same information to help passengers with a visual impairment) .

User Classes
* Public: people who are using metrobuses searching which line they will use, arrival time of the metrobus or looking at the city map. * Maintenance personnel: people who service, adjust, maintain and repair equipment

STAGE 2: OPERATIONAL CONCEPT FORMULATION
* Existing metrobus stops are being upgraded and some new metrobus stops built along for future metobus routes. This ensures that passengers have reduced waiting times and easier access to buses. * LCD displays on metrobus stops show arrival, departure and estimated time of arrival calculation information based on the vehicle tracking data. This tracking information is provided using satellite signals from the Global Positioning System (GPS) .The data is transferred to the control centre by GPRS communication. * Positions of all metrobuses are tracked so that predictions of arrival times on information displays at metrobus stops are continually updated. * The metrobus stop acts as an active environmental sensing node, powering itself through sunlight and collecting real-time information about the surrounding environment

STAGE 3: OPERATIONAL CONCEPT FORMULATION
* Main task
The system would provide real-time information on LCD display screens at these stops. The information indicate the fixed route of the metrobuses on graphic maps, the number of stops and the estimated time before arrival. * Human Task

The user will be able to check his current location, closest metrobus stop's location and...
