The major focus of highway agencies throughout the country is to provide a safe and efficient transportation system. In the past, these agencies did not always seek input on projects from other affected parties Recently, designing roadways to consider the capacity and safety issues while addressing its physical and human environmental setting has been emphasized through Context-Sensitive Design (CSD) initiatives. CSD is defined as the project development process, including geometric design, that attempts to address safety and efficiency while being responsive to or consistent with, the road's natural and human environment. It addresses the need for a more systematic and all-encompassing approach in project development which recognizes the interdependency of all stages and views them along a continuum. To achieve such balance, trade-offs among several factors are needed and are routinely made in most projects. The projects included here are examples of CSD projects. |
