Advances in electronics, computers, sensor technologies, software tools and communications made it possible to establish a connected transportation system where vital for control and traffic management information is shared among users and infrastructure in a speedy manner. This kind of connectivity provides a unique opportunity to model, control and optimize traffic in ways not possible before. In this talk I will cover examples where models and control and optimization techniques are used to improve traffic flow, manage congestion, improve mobility and safety with benefits to the environment. I will emphasize the use of analysis and how mathematical models are chosen based on the problem under consideration. For large complex traffic networks the use of simple mathematical models is replaced with simulation models or digital twins which are part of the control and optimization decision making in order to generate more accurate results. One of the examples to be discussed in detail is integrated traffic flow control using variable speed limit, lane change and ramp metering control. Another example where simulation models are used in a co-simulation optimization approach is a centrally coordinated cyber physical freight routing
