Abstract

The use of Global Positioning Systems (GPS) has been a springboard for many transportation related projects. GPS allows for efficient real-time capturing, storing, and transferring data in the field. The data can be manipulated, analyzed and mapped with the aid of Geographic Information Systems (GIS), visually displaying a robust product. When working on signal coordination solutions, transportation engineers rely on accurate, quantifiable data for making proper engineering decisions. The key components of information that is necessary for proper signal coordination is vehicle counts, speed, time and delay. The expanding GIS and GPS technologies have made it easier for one person to collect spatial data with attributes of time and velocity. This paper will compare some of the methods used to collect travel time information, and give clear reasons to why GPS is a better solution for collecting travel time data.
