Spain tests new traffic lights: red and amber combo aims to ease congestion
A new approach to traffic management
The Spanish Directorate General for Traffic (DGT) is piloting a novel traffic light system in Granada, designed to improve traffic flow and reduce emissions. Moving away from the traditional red, amber, and green sequence, the new system features a simultaneous red and amber light, a configuration previously unseen in Spain. This initiative aims to provide drivers with more control over their speed and braking, ultimately leading to smoother traffic movement during peak hours.
Granada's pilot program
The first tests of this unique system are underway at an intersection on the Chana district and Sierra Road in Granada. The local council believes this change can significantly impact traffic congestion. The initial response has been mixed, with some drivers experiencing confusion, but officials are confident that drivers will adapt quickly. The system's implementation marks a shift in the DGT's approach to traffic management, exploring options beyond the standard color sequence.
How the combined lights work
The simultaneous red and amber light doesn't mean drivers should stop immediately. Instead, it's intended as a signal for drivers to regulate their speed and prepare for a potential stop. If the traffic conditions allow, drivers can maintain their speed and proceed through the intersection as the light transitions to green. The DGT believes this allows for a more gradual deceleration, reducing the need for abrupt braking and improving overall traffic flow.
Potential benefits: time savings and reduced emissions
The DGT estimates that the new system could save drivers an average of 0.5 to 1.5 seconds per intersection. While seemingly small, this time saving can accumulate significantly during rush hour, especially at intersections with multiple phases. The city council estimates improvements of up to 7% in cycle time, leading to a reduction in emissions and fuel consumption. The local police confirm a saving of approximately one second when crossing the intersection.
Valencian roads also getting an upgrade
Beyond Granada, a new warning system is being rolled out on Valencian roads to alert drivers to the presence of wild boars. This system utilizes luminous signals to increase driver awareness and reduce the risk of accidents involving these animals. This demonstrates a broader commitment by Spanish authorities to enhance road safety and adapt to changing environmental conditions.
Comparing to european practices
The simultaneous red and amber light system is already used in certain European countries, but its introduction in Spain represents a significant departure from established practices. The DGT is actively monitoring the performance of the system in Granada to assess its effectiveness and potential for wider implementation across the country. The goal is to create a more efficient and responsive traffic management system for all drivers.
Addressing driver confusion and future plans
The initial confusion among drivers is acknowledged by the authorities. They are working to clearly communicate the purpose of the new system and encourage drivers to adjust their driving habits accordingly. The functionality is being presented as similar to the pedestrian crossing timers, which indicate the remaining time to cross. The DGT will continue to evaluate the system’s impact on traffic flow and safety before making any decisions about a nationwide rollout.
