This Guide is about designing highways that incorporate community values and are safe, efficient, effective mechanisms for the movement of people and goods. It is written for highway engineers and project managers who want to learn more about the flexibility available to them when designing roads and illustrates successful approaches used in various highway projects. It can also be used by citizens who want to gain a better understanding of the highway design process. The challenge to the highway design community is to find design solutions, as well as operational options, that result in full consideration of sometimes conflicting objectives. This Guide helps meet that challenge by provoking innovative thinking for fully considering the scenic, historic, aesthetic, and other cultural values, along with the safety and mobility needs, of our highway transportation system. This Guide is presented in three parts: Part I - The Design Process; Part II - Design Guidelines; and Part III - Case Studies. (Author/publisher)
