FIELD STUDIES AND INVENTORY OF FREEWAY GUIDE SIGNS

The first part of this report describes traffic operation field studies conducted on urban freeways in Dallas and Houston. Major signing modifications were made to the freeway guide signing by state forces exogenous to the research effort. Before and after studies considering lane volumes, lane changes and erratic maneuvers were collected and evaluated. Some specific and a few general conclusions and recommendations were offered. The second part of this report will document research conducted on various aspects of urban freeway guide signing. This report descibes the results and findings of a physical inventory of freeway guide signing in ten cities in the United States. Four of these cities inventoried were: Dallas, Ft. Worth, Houston and San Antonio. The six out-of-state cities were: Atlanta, Chicago, Denver, Kansas City, Los Angeles and New Orleans. Data were collected on numerous physical design features including: number of sign panels, number of concurrent routes, and bits of information. Message content and meaningfulness, as such, were not evaluated. A "bit" of of information on freeway guide sign was defined as a route number, destination name, or any one of 12 other similar message items.
