Title: ROADWAY MODELING AND DATA CONVERSION FOR A TRANSPORTATION FACILITIES INFORMATION SYSTEM

Availability: Find a library where document is available Abstract: Many transportation agencies are in the process of developing roadway management systems to assist with their rehabilitation and maintenance programs. All require a centralized data base to manage the large amount of data collected for each highway section. Described in this paper is a research project that used the utility industry (gas, electric, and so on) interactive graphic data base for highway applications. As a roadway section is similar to an electric line, many of the modeling concepts are therefore also similar. A computer model of the highway system was developed that used five types of facilities. Type 1 is a point facility (sign, signal), whereas Type 2 represents a highway span facility. The Type 4 and 5 facilities represent the data elements and the pictures associated with the interactive graphics. All data are stored at appropriate X and Y coordinates. The roadway model developed with the five facility types allows the user to trace the connectivity of the highway route as well as to obtain the requested highway information. Also described in this paper is a case study that was conducted to test the model. U.S. Geological Survey maps were digitized and merged with the Pennsylvania Department of Transportation's Systematic Technique to Analyze and Manage Pennsylvania Pavements condition information for roadways in a county in Pennsylvania. It was found that the facility models adequately describe the highway system. The user, however, must be careful in the digitizing process. Map document shrinkage and expansion (due to humidity) is enough to change the document location reference. It was also found that manual digitizing is extremely time consuming, and it is necessary to develop computerized interface data conversion routines.
