CITY OF DUBAI (UNITED ARAB EMIRATES) (2012/2014)
"Dubaï Al Safooh - RS Design – Traffic lights Expertise"

Problematic
The construction of the first tramway line in Dubai (the Al Sufouh Tram) was entrusted to Alstom-Besix Consorsium. It is completely powered by ground-based electric supply system. Ceryx Trafic System worked as a subcontractor for Alstom as specialist of road signalling for studies to commissioning. CeRyX Trafic System had raised awareness all project stakeholders on the importance and on the functioning of the priority for the tram.

Missions of CeRyX Trafic System
- Presented the principles of trams priority at traffic lights junctions
- Attended Alstom in developing and rereading general specifications and detailed system design
- Made recommendations regarding the implementation of tram detection loops on the 10 kilometers from the first line
- Participated in the development of the specification of each junction.
- co-authored the testing process and recipe of priority subsystems at traffic lights
- participated onsite in setting the final point of the subsystem during scale tests in preparation for the inauguration of the system

MARTINIQUE ISLAND (FRANCE) (2011/2012)
"Analysis & proportioning studies of N5 interchanges for the Martinique Island public transport implementation"

Problematic
The local authority of Martinique Island decided to improve the public transport service by creating a bus line with a high level of service. CeRyX Trafic System was the subcontractor of the engineering group of consulting firms which was chosen to be the main contractor support for this bus line. Our mission was to conduct urban development studies about the N5 lane – where the buses will run.

Missions of CeRyX Trafic System
According to the existing traffic flows, CeRyX Trafic System has :
- Estimated the 2015 traffic situation
- Calculated the intersections traffic capacity in 2015
- Realized a technical drawing of the intersections to optimize the bus line circulation
- Proposed an adapted  traffic light functioning for each intersection

CITY OF GRENOBLE (2010-2011)
"Manoeuvring area optimization – Intersection of Chavant/Pasteur in Grenoble"

Problematic
CeRyX Trafic System conducted studies, organized the works contract (from works supervision through completion) and the commissioning tests. In 2006, the realization of the tram line C created traffic disorders in the Chavant/Pasteur area: 2 tram lines cross in this place (lines A and C) and share a single station, located just between 2 difficult intersections. More than that, the traffic lights and the railway signalling interfered with the each other functioning.

Missions of CeRyX Trafic System
With the agreement of the state technical service and the qualified organism of France delegate, CeRyX Trafic System has imagined and created an innovative functioning: From now, some of the railways signalling missions have to be managed by the traffic light controller (road signage).
The railway signalling no longer manages converged routes, but still manages conflicting ones: the command of the railway needle and its security. This new managing solution permits a smoother global functioning and a bigger reactivity. Signalling communication with the driver is now simplified.

GRAND LYON (2009/2011)
"Take-over of the operation of traffic-light-controlled junctions on lines T1-T2"

Problematic
Tram lines T1 and T2 have been in service since 2001. The lines needed to be modernised and updated to improve priority at traffic lights and cut journey times. An experiment was conducted on four junctions on the T1 line in 2008. The results of this experiment were highly promising, and a decision was made to apply these same principles to all junctions on both lines.

Missions of CeRyX Trafic System
CeRyX Trafic System provided the following services :
- An assessment of the layout and workings of the existing system
- Recommended changes (layout and workings)
- Production of operational documentation in line with the new principles
- Adjustments after deployment
- Preparation of the lists of completed work
