“Intelligent traffic lights” in Merida a possible solution to traffic chaos.

MERIDA, Yucatán. – The corner  of Paseo de Montejo and Avenida  Colón  will be where state authorities will install the first “smart” traffic lights, as part of the Integrated Urban Transport System (Situr Sistema Integral de Transporte Urbano) in the city of Mérida. Smart traffic lights on Calle 60 across from Plaza Galerias and Prolongación de Montejo near Villas la Hacienda are also part of the new traffic light system, in an attempt to solve traffic problems in the area.


On January 5, state authorities launched the first phase of the Situr project, to monitor areas of high traffic such as the intersection of Jacinto Canek with Calle 128.

The first stage includes 159 intersections:·

  • 117 are already signalized.·
  • On the “Metropolitan Circuit” (Circuito Metropolitano) bus route there are 69 intersections (43 of them signalized).
  • Merida has a total of 297 signalized intersections with 109 in the downtown area.


The first phase of the project includes 7 stages with a total length of 281.3 kilometres (175.8 miles), beginning with the Metropolitan Circuit (Circuito Metropolitano) bus route, which has a total length of 123 kilometers (76.8 miles) in both directions.



The “smart” traffic lights synchronize the signal, governing the timing and duration of the lights.  The system is activated by traffic within 200 meters of the lights.  Travel time is reduced because priority is given to the heaviest flow of traffic.  



In Mérida’s metropolitan area, 1,441,622 million trips are made each day, of which 676,409 (49.9%) are by public transport and 454,000 (31.5%) are by private vehicles. The remainder are on foot or by bicycle.

The areas considered for the first stage are: Metropolitan, West Plazas, West University, Hospitals, Suburban Areas, Industrial city and Santa Gertrudis Copó. The system is expected to be fully operational by 2018.
