CITY OF AJACCIO (current of 2014)
"Traffic study of the seafront crossroads functioning in Ajaccio, during the phase of work"

The city of Ajaccio asked for CeRyX Trafic System to realize a traffic study as part of the works for the seafront outlets. The goal of the study was to improve traffic flow, and had to provide ideas of new traffic light crossroad functioning – especially on the castelvecchio intersection.

Missions of CeRyX Trafic System
- definition of 3 deviated traffic scenario, each one related to potential urban design for the Castelvecchio crossroad
- checking of the different crossroads functioning impacted by the deviated traffic, and proposition if necessary, of better functioning to absorb the additional traffic
- realization of measurements of crossroads capacities impacted by the deviated traffic to give the final schemes of the considered crossroads, with new urban design and traffic light functioning

"Dynamic simulation of the 60000 workers public transport system on the petrochemicals site in Johor"

The Petronas company have built a petrochemical complex near the sea in Johor. As this area is long as 5 km, 60000 workers are needed to make it works. They live in a camp, closed to the area. In order to bring them to the construction area, a dedicated bus lane has been setup. During this mission, CeRyX Trafic System assisted Technip company and participated to setup the public transport system

Missions of CeRyX Trafic System
- writting of a technical note with all the informations required to size the number of bus needed.
- metrics are determined, like exchanging times, bus boarding station functioning and 40 itineraries analyses
- collaboration to define the ground plane and make the bus system
- test ofthe system in all the area, one more time, with the dynamic simulation, with something like 300 buses circulating and 800 personal cars.
