Traffic Light System

The Traffic Light System by Citelum: • Planning of all the possible scenarios for each traffic light (beam patterns)

• Management of priorities by type of vehicle (bus, bicycle, car, tramway, etc.)

• Event management: change of the beam plan in case of an unexpected event (accident, demonstration, etc.)

• Traffic management: adaptation of the timing of traffic lights to regulate traffic

• Equipment compliance for people with reduced mobility and visually impaired persons

Did you know?

Fluidity and road safetyThe traffic light system defines the rules of priority at intersections to better ensure the security of users.

Once connected, it takes into account all the available information in order to fit real-time traffic, priority hierarchy of vehicles as well as other events which could impact traffic.

Citelum, thanks to its experience in urban mobility, guarantees more optimized and fluid trips thanks to the implementation of a smart and controlled traffic light system.

You wish to:• Ensure the safety of users on the roads• Get a smoother-flowing traffic• Facilitate the circulation of emergency vehicles• Improve the citizens’ quality of life

In France, there are 205 000 crossings of

red light violations per year

A « Green Wave » rewards people who

drive at a reasonable speed, with a road

marked with green lights

Crossing a red light is punishable with a €135€ fine and the loss of 4 points on

the driving license (France)

TYHow does the Traffic Light System work?

City analysis:• Analysis of the vehicles flows and number at each intersection to determine the most appro-

piate duration of red / green cycles

• Study of users’ needs and identification of places of interest

• Integration in the analysis of the « Urban Transport Plan » of the city (when it exists)

Equipment and urban planning proposal:• LED traffic lights

• Cabinets on the road (controllers)

• Safety equipments: radars, magnetic sensors, video cameras, etc.

• Materials for visually impaired and disabled people: call buttons for pedestrian, magnetic loops, audible traffic lights, etc.

Works, Operation and Maintenance:• Equipment installation

• Planning of the « beam plan » and installation of a control software

• Equipment maintenance (obsolescence or deterioration)

• Quick intervention in case of an accident (<4h)

Supervision with MUSE®:• Remote monitoring equipment

• Real-time control and diagnosis of all equipment and services

• Communication with the command center of the city to manage emergencies and other events

• Data analysis

• A safer and more attractive city

• Traffic and related pollution reduced

• Optimized maintenance and operation through the use of LED and robust materials
