Traffic Light

  • Client: TACSE
  • Year: 2010

Tacse and Stimulo partnered to do the technical development of the new LED traffic light of Barcelona.

In order to modernize the city facilities and catch up with the latest technologies, Barcelona City Council decided to change its traffic light networking system. Tacse, the Spanish leader in the design and manufacturing of railway equipment, got the rights to produce the new LED traffic light. To meet timings, costs and regulation requirements, they came to Stimulo to make the full technical development of the traffic light. Stimulo and Tacse faced two big challenges: turning the selected design into a robust solution while meeting the manufacturing and costs requirements.

The engineering team had to face the multiple technical demmands, like the wind ressistance of multiple modules, which was solved through an internal aluminum multi-column that met the regulatory and environmental requirements.

Given the high innovative materials requirements, Stimulo collaborated with AMADE (Center of Analysis of Advanced Material for Structural Design of Girona University).

Another critical issue of the development was the ability to customize and automate some processes, especially the ones using 3D and parametric software solutions. This made the decision-making process faster and clearer to all the team members. Two prototypes were made before making the final molds. The first helped us to validate the dimensions and proportions of the traffic light, while the second helped us to optimize the assembly sequence. In order to ensure a perfect result, stimulo supervised the production and the pilot run series. During these few years Stimulo has collaborated closely with Tacse in the management of innovation through new products.
