MISSION CRITICAL COMMUNICATIONS FOR TRAFFIC
MANAGEMENT SYSTEMS
S.N. Boriyev
TATU Karshi branch named after Muhammad al-Khorazmi
A basic tenet of smart city programs is the deployment of technology to
manage assets and resources more efficiently. Within this movement, city
transportation infrastructure is often a top priority, given its extensive use and
impact on residents, businesses and emergency response. Now with the growth
of smart transportation systems, the arrival of connected vehicle technology and
the future of autonomous vehicles, there is an increasing demand for maximum
network bandwidth and high availability communications.
Architecture of a smart traffic management system
The Traffic Management Center (TMC) is the central facility where
vehicle and pedestrian movement is monitored and controlled. The Digi router
provides secure and reliable communications between intersection equipment
and the TMC, while Digi Remote Manager® (Digi RM) provides central control
over the communications infrastructure. The Traffic Cabinet Communications
diagram presents the various entities and their connections. The principal system
functions are as follows:

Backhaul communications:
Multiple concurrent cellular and fiber links
ensure continuous communications with the TMC. IPsec VPNs ensure secure
passage through any network.
•
Local network:
The router’s built-in four-port Ethernet switch supports
connections to IP-enabled equipment within the cabinet. A Power-over-Ethernet
(POE) switch expands the port count and supplies power to multiple IP cameras.
