Question

Because traffic is growing heavy in the central part of a city, traffic engineers are planning to change all the streets, which are currently two-way, into one-way streets. Explain how to model this problem

Short answer

The problem of traffic can be modelled by creating a G-shaped undirected graph to represent the city's streets and locations. The graph's edges will represent the streets, whereasthe vertices will represent the traffic intersections.

Step-by-step solution

Concept/Significance of graph

Graphs are extremely valuable and widely used data structures. They are used to explain a wide range of object connections and, in practice, may be applied to nearly anything.

Explanation

Visualising the city's top view as a graph using various symbols and notations can be done by creating a G-shaped undirected graph to represent the city's streets and locations.

The graph's edges will represent the streets, whereas the vertices will represent the traffic intersections.

The graph is then made orientable such that it becomes firmly linked, resulting in a city with suitable direction.

Thus, the problem of traffic can be modelled by creating a G-shaped undirected graph to represent the city's streets and locations. The graph's edges will represent the streets, whereas the vertices will represent the traffic intersections.
