Traffic Light System

• The system is a roster of four times in each branch of the road, except to turn left directly

• If one branch of green lighted streets, the only branch right next to the one who should be allowed to turn left directly

• In the four-way branches, each branch 2 edge must be paired sensor road vehicle counters.

• Sensors are used to count the number of vehicles in the four branches of the vehicle in one cycle time, so the program can determine the portion of the red light and green light in each branch   

•  Software will determine the most number of vehicles based on data that have been obtained from the sensor , and determines the amount of time for each branch of the sensor , branch with most vehicles will get more green light times

• If there is no vehicle in one of the branches, then the system will turn on the red light on the branch, and will continue until there are vehicles that are in the branch

Software Processes

In software-making,there are 6 different type of software process:
1.Waterfall
2.Prototyping
3.Iterative Developement
4.Rational Unified Process
5.Timeboxing
6.Extreme Programming and Agile Process

Each type of process have its own benefit and shortage

	1	2	3	4	5	6
Risk on software-making	H	L	L	L	L	M
Quality of the product	H	L	H	H	H	M
Time Efficiency	L	H	H	H	H	H
Maintainability in the process	N	Y	Y	Y	Y	Y
Management	Linear		Linear	Paralel	Paralel	Paralel
Difficulty on software-making	H	M	H		?	M

H = High

M = Medium

L = Low

N = No

Y = Yes
