green zone is an area in the center of the city

PROBLEM DESCRIPTION

 

A city has decided to create a green zone. The green zone is an area in the center of the city in which there is restricted access by motor vehicles. Vehicles (such as cars and trucks) are only allowed to enter the green zone if they have a green zone permit. The permit number is encoded on a bar code sticker, which is displayed on the windshield of the vehicle. When the vehicle enters the green zone, a remote laser scanner reads the barcode permit number and transmits it to the Green Zone Monitoring System. When the car leaves the zone, its bar code is also scanned and sent to the system.

 

The system maintains a database of pre-paid green zone permits, from which the owner of the vehicle is billed for each trip and for the duration of the trip. There is a maximum charge for each day. The amount billed varies by time of day: peak-time, off-peak and night, and vehicle category, such as car, SUV, truck, taxi, bus, etc… The amount is deducted from the pre-paid green zone account at the end of each green zone trip. A person that resides in the Green Zone and has a vehicle registered in the same address needs to apply for a resident permit, which allows unrestricted access into and out of the Green Zone.

 

If the car does not have a green zone permit, then a video camera takes a picture of the vehicle license plate. From an external vehicle license database, the address of the vehicle owner is determined and a fine is sent to the driver.

 

The system includes an automated vehicle license recognition capability, which decodes vehicle license photographs taken by the vehicle camera. The system is also accessed by Green Zone operators who may view information about green zone permits and accounts, green zone trips, monitoring points, and vehicle fines.

 

The order of the sensors at the green zone entry and exit points is vehicle location sensor (which detects the presence of the vehicle), vehicle laser scanner, and vehicle camera. you may assume that each of these sensors is asynchronous.

 

You may assume that there is a microcomputer at each entry point and each exit point, to which are connected the vehicle location sensor, vehicle laser scanner, and vehicle camera. You may also assume that there is one centralized server, which stores all the system information in a database.

 

 

·       1. For the above described system specification, identify the architectural styles that are likely to be the appropriate. Tabulate the reason for selecting and rejecting various architecture styles.        

 

·        2. Finally, sketch out the overall architecture that would meet the specified requirements.
