Functional ITS Design Issues

摘要: This chapter discusses a number of topics that form the conceptual framework and building blocks for developing ITS designs as described in chapters follow. Topics include: Relationship design approaches to general transportation planning principles. The impacts volume, speed, density, capacity issues, recurrent non-recurrent congestion are introduced discussed.
