Traffic flows improves with InfiNet Wireless

Introduction

By improving the signal timing between traffic lights, Georgia’s Regional Traffic Operations Program (RTOP) aims to improve traffic flow and cut vehicle emissions. To achieve this, it needs the fastest possible communications infrastructure. InfiNet Wireless provided the best bandwidth and the most fluid, manageable infrastructure through a wireless broadband solution. RTOP is now able to monitor all corridors from GDOT's Transportation Management Center over Ethernet. This creates quicker response times to repair signal problems.

Requirements

• Fast, reliable communications that contribute to better traffic flow
• High bandwidth networking that can transport data rapidly across city and county borders
• A system quick enough to synchronize signal timings across a vast metropolitan area
• A flexible system that can be adapted as the infrastructure changes
• A networking infrastructure that is cost effective to install, reliable and can be managed with maximum economy
• Performance, reliability, scalability
• A good local support team

Solution

• Installation of high capacity point-to-point wireless networking
• Specifically, InfiNet Wireless InfiMAN 2x2 R5000-Smc/54.300.2x63.2x21/4 licensed as a PTMP, across 30+ locations in the region covered by the Georgia Department of Transport
