# Case study solution of southwestern university traffic problem with solution

The expected problem would be after the game from the stadium to the interstate highwayhence the university planning committee is thinking of turning some streets closest to the stadium into one-way streets. How must SWU address the possible traffic problem caused by the football game?

Related Questions - If there is no expansion, what is the maximum number of cars that may actually travel form the stadium to the interstate per hour?

Which streets would you recommend expanding to get the total capacity of the system to 35, per hour? The case requires finding the maximum number of cars that the roads from the stadium to the interstate can accommodate. Hence, the maximum flow network model will be used.

Do not expand the roads Status Quo - As stated that based on past experiences, as long as the street capacity is within 2, the problem of traffic congestion is not too severe. Expand the roads - On the other hand, the severity of the problem increases dramatically for every 1, cars added on the street. The figure is different from the 33, cars that Dr.

Lee suggested because he only took into account the number of cars coming out of the stadium node 1. Although the three roads directly from the stadium branches 1- 2, and support a total of 33, cars, the remaining roads where these branches lead to cannot accommodate the same capacity. For example, 15, cars can travel from node 1 to node 2 but only 12, cars can traverse from node 2 to node 5 — leaving 3, cars stuck.

### Southwestern university traffic problem

In order to increase total capacity to 33, road can be expanded in order to accommodate all 15, cars who travelled from At the same time, road can also be expanded to accommodate the cars from road now with 15, capacity after expansion and road 8, capacity.

Expanding road to accommodate a total of 15, cars and expanding road to accommodate a total of 23, cars will increase the maximum capacity of the system to 33, as shown in the table below: The total number of cars from node 1 is only 33, so even if the subsequent roads from node 1 will be expanded, the maximum capacity would depend on how many cars can the roads from the entry point can accommodate.

From our initial expansions which increased total capacity to 33, we can expand road to move up total capacity to 35, There are only 12, cars that can travel road However, node 3 can accommodate up to 14, cars 8, for road and 6, for road To maximize the capacity of node 3, road can be expanded and this would result to a maximum capacity of 35, cars. Results showed that only 28, — and not 33, — can actually pass the roads from SWU to the Interstate every hour.

The same results showed that if SWU wants to accommodate 35, cars at any time, they have to expand 3 roads: As the numbers indicate, this group recommends that expansion works must be done to meet the projections of the SWU Board. However, this recommendation comes with a caveat — important considerations prior to commence of the project: Starr said he wanted to have a 35, capacity road network.

- There are only 12, cars that can travel road
- Lee has sug- football program now that a big-name coach has been hired.

However, as can be seen, 3 roads must be expanded to accommodate this objective. Now, perhaps it is too much to beg the question for their basis of expansion. His projections are due to their high- profile football coach. Is this all worth it? Are there rights-of-way that will be affected? Will this hamper the day-to-day operations of the campus?

Can this coach really haul in the 35, cars — enough to pay for the roadworks?

### Expert Answer

Have a sustainable program Roadworks are certainly not cheap. To give an actual computation of a road network, the actual cost in constructing a 1 km x 6. This does not yet include the profit margins. These are the figures that the football matches must pay for initially. And what about right of way? SWU is expanding, therefore are these road networks exclusively theirs to begin with?

Roads are likewise expensive to maintain. At least, all roads are only guaranteed to last 3 years without any repairs. Thus, sustainability is the key. If the money to pay for the roads will solely come from the football games, then SWU must sustain its football team. Make comprehensive plan on roadwork implementation Say that the project pushes through, the next issue to face is the problem of road expansion.

Does SWU implement the expansion simultaneously? The expansion must meet the timeline before the season opens.

- Roy worked at general motors until the factory was closed down and the work sent overseas - duration;
- Lee has suggested that the current capacity is 33,000 cars per hour.

Offhand, they are the most benefitted at this point. SWU School The board must have a logical explanation for the road works. Authorities The projected income from the games must outweigh the expenses and there must be a medium to long-term planning involved to sustain the expansion of the road networks.

- However, this recommendation comes with a caveat — important considerations prior to commence of the project;
- How must SWU address the possible traffic problem caused by the football game?
- From our initial expansions which increased total capacity to 33,, we can expand road to move up total capacity to 35,
- These flows include some streets closest to the stadium being trans formed into one-way streets for a short period after each game with police officers directing traffic;
- Expand the roads - On the other hand, the severity of the problem increases dramatically for every 1,000 cars added on the street.

More so, if the expansion works commence, there must be appropriate measures taken so as not to disrupt campus operations. However, if this program fails, the students may Campus eventually bear the burden of these costs being added to their operation matriculation. Surrounding Initially, if rights of way are affected, SWU must compensate the Community owners accordingly. Also, if the work pushes through, SWU must address the noise and emissions that may be caused by the works.

Otherwise, the expansion poses huge discomfort to the surrounding communities as well as risk to health.
