This paper presents a parsimonious review on the definitions, classifications, objectives, constraints, network topology decision variables, and solution methods of the Urban Transportation Network Design Problem (UTNDP), which includes both the Road Network Design Problem (RNDP) and the Public Transit Network Design Problem (PTNDP). The current trend and gap in each class of the problem are discussed and future directions in terms of both modeling and solution approaches are given. This review intends to give a bigger picture of transportation network design problems, allow comparisons of formulation approaches and solution methods of different problems in various classes of UTNDP, and encourage crossfertilization between the RNDP and PTNDP research.
