2. Multiple routes per edge:
Alternatively, if the routes are meant to be stochastic, each element can consist of a list of (route, probability) tuples, where the first element in the tuple is one of the routes a vehicle can take from a specific starting edge, and the second element is the probability that vehicles will choose that route. Note that, in this case, the sum of probability values for each dictionary key must sum up to one.
For example, modifying the code snippet we presented above, another valid way of representing the route in a more probabilistic setting is:"
