Transport policies in polycentric cities

This paper studies how transit lines should be developed in polycentric cities. In several growing metropolitan areas, local authorities have to decide whether rely on existing radial connecting suburban areas the city-center, or develop new circular directly areas. An efficient system aims at reducing external costs of transport (congestion and pollution) by attracting private car users. We study effect two types policies modal split. First, we compare three administration regimes (public, semi-public private) transport. Second, consider opening a line linking suburbs. find that it reduces aggregate user cost but is not Pareto-improving unless crowding high lines. Our analysis complemented numerical illustration based an open source Fortran program. tool needs relatively small set data can used policy makers wishing investigate pricing reforms possibility for specific case study.
