Abstract:Traditional contracting and procurement procedures when applied to electronic data communication. computing, and software are not entirely appropriate for Advanced Traffic Management Systems, particularly if low-bid is the prime consideration for award. Purchasing and procurement legislation for the State of Texas and other states was reviewed to determine applicability in procuring Advanced Traffic Management/Intelligent Vehicle Highway Systems. In particular, researchers considered compatibility issues in expanding existing systems. The current Texas Information Resources Act (SB 381), enacted in mid-1994, appears to offer the most flexible mechanism for implementing and expanding these complex systems. Through the catalog purchase procedure, TxDOT bas the opportunity to more nearly specify the most appropriate traffic management system for a given set of circumstances and to provide for expansion and extension of systems with minimal compatibility problems. National efforts to develop a standard architecture and communications protocol will further enhance the ability to procure compatible system components. TxDOT should continue to monitor and participate in those national development activities.
