Traffic jam solving
When I took an over view of the situation of traffic in major cities of Vietnam such as Hanoi and Ho Chi Minh City, it’s getting very serious by time passing. I was wondering and curious to look for any possible solution for the current circumstances and the causes of traffic in Vietnam, and recommends suitable groups of problem solving to decrease traffic jam in big cities of our country.
In our country, bus have been running to a big role of vehicle transportation of numerous of citizen in Vietnam on daily basis. This is one the vehicles transportation methods using by public passengers that make few positive external benefits like produce less toxic toward the environment, comparing toward to number of toxic airs that were produced by cars and sometime reduce the traffic crisis of big urban city in our country.
My goal is exploring the way that bus could help thousands of students in Ho Chi Minh City will have a better way to go to school every day without dealing with traffic jams, avoiding late to class. Bus not only bring beneficial toward student, it can be a great tool for the traffic economic in Vietnam.
In order to achieve our goal, I will include with the method of the transportation of the bus, transportation map of Ho Chi Minh City and the requirement of moving around of the people.
Ho Chi Minh City is one of the busiest and biggest city in Vietnam, with enormous infrastructure and convenient. Because of that, the transportation of our bus are very convenient thanks to a well-regulated or comprehensive road system and safety for the people who walk to the bus, what’s that mean is people would have good abilities of being safe to walk on side street to the bus.

The component of bus system
The component of this system included with parking at the terminals of the route, the measurement stations on the route, types of vehicles used in the system. Roads are going through student pickup stops, roadways that often cost in traffic jams or high traffic levels. Roads run through large populated areas and have a large student population as well.
As we can see, which of the transportation route of bus always have the start line and the finish line. In order to build a bus route, we will model the construction of bus routes on a particular route. The rest of the route will apply the same model. Here, we choose the route “depart from the starting station, which is the central bus station, go to Tran Dai Nghia school, the central school in District 1, contain the most demand consumers(student) toward the bus transportation. With this route, we use the model and apply the maximum flow problem to construct the path. Included with:
-Starting point: City Center Bus Station
-Finish point: Tran Dai Nghia school
From the point of departure to the destination, the bus must pass through stops built on the roads. Each stop is a peak on the graph. Every points on the graph are the connection road between each peaks.
The number of the graph is calculated based on these factor: the number of students distributed on the routes, road bumps often occur, traffic jam high density roads and the length of the road.
Road name The amount of students distributed Traffic Jam High traffic density Length(Km)
Le Thanh Ton 50 1 3 2
Nguyen Hue 25 4 2 2
Tran DaiNghia 156 3 6 1
Ly Tu Trong 32 1 3 4
Dong Du 72 0 1 1,5
Explanation: Display the numbers from small to large traffic density from low to high, the level of traffic jam from less to large.
Based on the above analysis, we have the maximum flow problem as follows:
(Model of each route on the road)
In there, every peak in the graph are described as follows:
Peak one: The starting point, the central bus
Peak two: Pick up passenger station at Le Thanh Ton
Peak three: Pick up passenger station at Nguyen Hue
Peak four: Pick up passenger station at Ly Tu Trong
Peak five: Tran Dai Nghia School
Applying the formula for the maximum flow problem, we get 9. Corresponding to the way on the graph.
1 ->2 -> 4 -> 5 = 9
From the above results, we construct the bus route: The starting point -> pick up passenger station at Le Thanh Ton -> pick up passenger station at Ly Tu Trong -> Tran Dai Nghia school.
If we do not follow the result number from this maximum flow problem, which is 9, it will cost traffic jam and increasing chances of accidents on the road
