Intelligent traffic management system in Lisbon

in Regional · 22-05-2010 00:00:00 · 0 Comments

Lisbon will soon be implementing a new traffic management system, which is expected to save drivers 30 percent of their time spent in the capital’s traffic jams.

This new technology to be installed throughout Lisbon allows the system to control the city’s traffic with intelligent networks, which in turn controls the changeover time of traffic lights. Besides the time advantage this system brings, it also cuts down CO² emissions considerably.
Lisbon Council signed a protocol with Siemens, the company developing the system, on Friday for the installation of the intelligent system network throughout the capital.
Francisco Rauter, a Siemens traffic solutions specialist, said “Using intelligent algorithms for control, traffic can be managed. This is analysed in real time by cameras spread throughout the city, which control the traffic lights in order to optimize traffic.”
This system also assesses traffic flows at certain times of the day, if there are any accidents, construction work or other situations that might affect traffic.
This technology is already being used in the USA, Germany and the United Kingdom, having improved waiting times in traffic by 30%. The date for the installation of this system in Lisbon has not yet been set by Siemens, although the company disclosed it will be soon.
If these changes are made together with the planned switch to electric vehicles, the path to improve the city’s sustainability will be set. By 2020, the government hopes that 10% of all vehicles circulating on Portuguese roads will be powered by electricity, hoping to guarantee a 25% reduction of CO² emissions.
Another innovative technology that might be put into practice in Lisbon are the ELV (Extra Low Voltage) traffic lights, which work at 48 volts, instead of the conventional 200 volts, representing huge savings in energy.
