This publication, “Illinois Traffic Crash Facts and Statistics for 1998,” is designed to serve your needs in researching and reviewing motor vehicle crash involvement in Illinois. Illinois continues to work to reduce traffic deaths and injuries through safety programs, such as education and enforcement of seat belt, child restraint and DUI laws.
It is well known that urban form is highly correlated with the evolution of transportation systems. In order to develop planning tools that are responsive to the complicated interaction between transportation and land use, it is helpful to identify the typical characteristics of the development of urban form. The relationship between transportation
