save time&energy / traffic light

save time&energy

This concept designed to solve problems common to cross streets in large cities.
traffic signals display time waiting in each root. existing traffic signal displays are programmed according to statistic data extracted from traffic studies.so the cross time for roots is static; but the dense of cars all day and night long is unpredictable. Solving the problem I proposed a dynamic system that :
• counts number of cars crossing in each root any time,
• compares root crowds,
• and states optimum cross time for each root.
this concept helps to decrease fuel consumption,metropolis air pollution and dead time behind traffic signals
