In spite of Confirmed increase in vehicle fleet Some drivers are licensed in the state technical solutions Can be adopted in cities To help with blood circulation. Among the most defensive are adaptive cues, also called intelligence.
The Recife As well as all the cities in metropolitan areaThey suffer from a lack of modern equipment that helps ease traffic. The capital, for example, has not yet captured it.
For those who don’t know, adaptive traffic lights allow for real-time programming, balanced according to the volume of road traffic.
That is, through the sensors, It is possible to program more green time for a specific street or road Which has more vehicles, at the expense of another, with less traffic, for example. The sound sensor, installed on the track, helps with programming.
JABOATÃO starts in the fore
The Jaboatão dos Guararapes municipality leads the way in the Recife metropolitan area. It will have, by the end of 2022, a central real-time traffic control system.
The traffic light network modernization project is in the process of bidding and will include 40 intersections with smart traffic lights operating in a real-time autonomous mode.
The system will operate intermittently until traffic lights begin to open and close when necessary, depending on the vehicles’ demand.
The traffic got worse and there was no time or schedule left. Understand the reasons
According to Jaboatão City Hall, everyone will work with data connections, broadband connectivity and a 4G data chip. Virtual loops will count vehicles by cameras. And each camera will have four virtual rings, that is, they will consist of four rotating lanes.
This information will be transmitted to the center, which will make the programming in real time and change direction intelligently, according to the number of vehicles on the main and secondary roads.
The project also has a solar electric generator for the main intersections in the municipality and a UPS for up to three hours in the event of a power outage.
Reeve is still analyzing
While Jaboatão is bidding, Recife is still analyzing the possibility of adopting smart traffic lights. The municipal administration was to give the go-ahead to the Traffic and Urban Transport Authority (CTTU) to determine the best technology to use among the many on the market.
But, as explained by the head of the CTTU, Taciana Ferreira, there are still no forecasts for the purchase of equipment. We have run some tests with the latest technology and got positive and negative results. That is why we have no horizon to say. But we continued our studies.
We also identified areas that have the potential to obtain a positive result, such as in the lanes of roads that do not experience significant interference. But adaptive traffic lights are still a high investment. That is why we continue to bet, in parallel with this analysis, on traffic engineering solutions that improve road capacity,” he explained.
To get an idea of how much development is required in the technological management of city trafficRecife’s traffic light network consists of 700 traffic lights, and consists of equipment that accepts, at most, fixed schedules, which cannot be changed according to the volume of traffic. They do not adapt.
In the second period of the State of Giraldo Giulio (PSB), Recife occasionally tested two smart devices, in the neighborhoods of Pena and Imberibera, at a time when exit from the southern region was closed after the implementation of the blue belt buses on Avenida. Antonio de Guys, in Pena. It was working at the time, but then the traffic lights were removed.
Professionals working in the sector, hear them JC, Claim that Recife is over underdeveloped in this area. That many cities have already adopted this technology, such as São Paulo (SP), Porto Alegre (RS), Belo Horizonte (MG), Vitoria do Espírito Santo (Spain), Osasco (SP), and Duque de Caxias (RJ).
The same experts also point out that investment in transportation technology is more of a public administration policy initiative than a high-cost investment. While the constant-time controller costs from R$15,000 to R$20,000, those capable of operating in adaptive mode range from R$35,000 to R$40,000.
For each crossing, the cost will be, on average, 80 thousand Brazilian reals. And in the case of Recife, it is expected that it will be necessary to use them on up to 250 of the 700 traffic lights, representing a total investment of R$ 20 million for the municipal administration. Experts say adaptive traffic lights greatly improve traffic even when they don’t solve the problem.
