## Question 2## aWe have seen in class that a norm penalization has the property to provide results with a lot of entries equal to zero. We exploit this property of the norm to study spatial traffic patterns. For this we study the following optimization problem: ## bThe matrix represents information on the traffic patterns. For example, we can expect some neighboring links to have the same traffic conditions. In particular, we can encourage neighboring links to have the same speed. We realize that two links and with travel times and and length and have the same speed if and only if ## cIn this section, we will experiment our traffic pattern with different |
