review text: The book deals with modelling of the dynamic processes performed by flows of vehicles in a road network. The flows form a dynamic system, input of which is given by a set of vehicle inflows at individual origin network nodes for each origin-destination pair. When the elastic departure time is considered, the input is described by the cumulative numbers of vehicles departing from the origin nodes for the given destination nodes during a given time period. The basic parameters, which are used here to describe the system behaviour, are time dependent values of the inflow and the exit flow for each network link and the number of vehicles on the link for each origin-destination pair at each instant of time of the given time period. The following common constraints are required for above values in any dynamic model presented in the book: a) relationship between state variables (the number of vehicles on the link) and control variables (the values of inflow and exit flow on the link); b) flow conservation constraints; c) flow propagation constraints; d) definitional constraints; e) nonnegativity constraints; f) boundary constraints. Besides the common constraints, which are required for usual case of a dynamic flow system, the vehicle drivers are supposed to comply with a general rule of behaviour. The rule of behaviour states that any vehicle driver chooses the time shortest way to his destination whenever he has a choice. The authors made an assumption that each vehicle driver is given the relevant information about the state of network in the considered system. Various cases are studied under these presumptions. There are completed mathematical programming models there for the instantaneous and the actual traversing times, which are known to drivers for their decision making. This way, the instantaneous dynamic user optimal route choice model and the ideal dynamic user optimal route choice model arise. It is proved that an optimal solution of the programs mentioned abov…
