There are several companies specializing in a Digital Traffic Management System and some key factors that a design must include are the following:
Ensure that central systems are capable of network latencies during data transmissions. New communication protocols may be warranted which will be event-driven as oppose to the old polling-based protocols.
Making sure whether additional equipment will be required for an IP-based cable network from a TDM-based network with drop and repeat to be interfaced.
The execute of a bench test of compression equipment and video transmission before field installations, to make sure the minimal tolerable bandwidth necessary for the required video resolution and quality is present.
The reason for a digital traffic management system speaks for itself if you look at the reasons why it is a 100% better system as oppose to traditional systems. During the life of digital systems traffic volumes on arterial roads will increase dramatically. Signalized intersections will also increase and the best of all is that city road is less congested as it usually is suffering during incidents caused on the freeways. The traffic volumes of adjacent freeways will dramatically increase.
The city staff has improved ability to manage and monitor traffic in actual time and incidents will be responded to in a comprehensive and much faster manner. City’s neighbors will be increasingly aware of similar issues and new equipment installed will be creating integration of activities and better cooperation.
