CURRENT STATUS AND PROSPECTS FOR REAL-TIME CONTROL

"Real-time" may mean one thing to system designers and another to system operators. A definition offered by this workshop for "real-time control" is: The capability to dynamically control traffic based on existing and projected conditions. Varying methods may be employed to achieve real-time control and these methods are often dependent on system type and complexity. Relatively little use is yet made of the great potential of real-time control. The industry is characterized by: A few "high" technology sectors but the majority have access only to low technology. Embryonic, government funded industry with limited free market or competitive driving forces. A fragmented approach to the development of software packages by Universities and DOTs, funded by taxes. This Workshop concluded that the industry ia a mess. It is fragmented with low incentives for private companies to invest. As a consequence: Integration of software packages is difficult to achieve (e.g., signal control and freeway control software). Maintenance and support of software is ineffective and inefficient. Only well funded organizations can afford the development costs (which cannot be recovered by selling several software packages.)
