This text illustrates the process and elements of urban transportation planning, design and impact estimation, and offers practice in undertaking typical projects. It focuses on the linkages and interaction with public policy on user service levels and resulting design and impacts. Reviews and design modifications are essential and integral parts of the creative transportation design process, providing immense challenges in combining technical excellence with established and evolving public policy. The book concentrates on the application of generally accepted procedures of transportation systems design. It should assist in providing a perspective on the total process, so essential to understanding and participating in effective programme and project management, and in maximizing effective project control and administration. The material also reviews selected fundamental concepts that should enable people with backgrounds in economics, urban and regional planning, and related disciplines, to become aware of projects and their scope likely to be encountered in practice. It presents analysis formats suitable for manual or computer estimates.
