Creation and customization of a GIS-based traffic control planning tool
The purpose of this study is to develop a tool that will assist in the development of traffic control plans. Using information from TxDOT Dallas District and several other sources, a GIS-based map has been assembled that combines data from many different formats into one user-friendly environment. The capability provided in the tool includes geometric properties of all TxDOT-controlled freeway segments, as well as daily and hourly demand data and capacity information specific to both general and HOV lanes. By selecting a segment on the map and opening the tool, the user can easily navigate through the collection of data in just seconds, which will significantly reduce the amount of time required by the traffic engineer to gather site-specific information when analyzing temporary traffic control.
