RESULTS OF THE PORTABLE TRAFFIC MANAGEMENT SYSTEM OPERATIONAL TEST

Minnesota Guidestar, as part of its program to establish an intelligent transportation system (ITS), supported the development of a portable traffic management system (PTMS). This paper describes PTMS system design and presents the operational test results. The PTMS system components include a traffic control center (TCC), closed circuit televisions (CCTV), portable camera mounts, spread spectrum radio, changeable message signs (CMS), a portable traffic signal, and highway advisory radio (HAR). Video images collected from the CCTV cameras are digitized, composed, and sent to the TCC via spread spectrum radio. This information, along with data gathered from an event sites existing traffic control infrastructure is processed by traffic control personnel. Based on the conditions identified, the TCC operators implement changes to existing traffic control infrastructure, the information is provided on the HAR and CMS, and the cycle time of the portable traffic signal. The operational test consisted of evaluating PTMS at six event sites in the Twin Cities area including the Minnesota State Fair and a Senior PGA Tour event. The operational test evaluation assessed the effectiveness of PTMS in the following categories: transportation system impacts; user acceptance; system costs; system performance; and system benefits.
