Old proprietary architectures and centralised operations that are often inadequate and inflexible have been overtaken by a new generation of traffic management systems whose open, distributed architecture enables them to be incorporated and upgraded.
TRENDS applies the technologies of open distributed systems and networked, event-driven resilient distributed databases and the ANSA distributed systems architecture to provide event-driven services across the Internet, using industry standard browsers for the client interface.
The TRENDS design is applicable to any event-driven application. In the TRENDS project the chosen application area is road traffic information and control and, by building a working pilot system, TRENDS shows how: 1. information may be gathered in one city, passed in "real time" over the Internet, manipulated on a server in another city and then made accessible to users (both in the original source city and elsewhere) as a variety of services accessible via browsers 2. existing legacy traffic control systems may be incorporated into the client/service architecture and carried forward and developed rather than becoming isolated and stagnant.
In the traffic control marketplace this opens up a new market area. Currently, traffic control systems are custom built for the application, using bespoke software, with all the risks of timescale, budget and reduced technical goals. Their very cost limits their application to large cities or regions. With TRENDS a traffic control systems manufacturer or systems house can now : 1. offer a service over the Internet, enabling the user organisation - the road traffic authority - to buy traffic control services on a "pay as you go" basis, thus making such systems affordable by many more cities and regions 2. incorporate information from existing, legacy systems, encapsulating them and enabling the overall traffic control system to evolve and develop unhindered by the past.
