JIMENEZ, MARGARITA  e  SARMIENTO, IVÁN. ADAPTIVE CONTROL SYSTEM AND OPTIMIZATION OF ROAD TRAFFIC IN A SIGNALIZEDCORRIDOR APPLICATION TO THE CITY OF MEDELLIN. Dyna rev.fac.nac.minas [online]. 2011, vol.78, n.169, pp.71-78. ISSN 0012-7353.

There are three key aspects to consider in designing an adaptive control system. The first aspect is related to the nature of the traffic phenomenon. This is far of being approached from the perspective of a deterministic model. The second, is inherent to a physical reality, considering that the road network, regardless of their design and / or establishment support a maximum traffic flow and a maximum density defined by their size, number of lanes and traffic conditions. All demonstrate, that more sophisticated than the system is, it is not possible to improve the performance of traffic flow per unit of time, beyond the physical limitations imposed by the road design and traffic regulations. On the other hand, initial investment costs plus operating costs and external costs related to the efficient flow of traffic are a third factor to consider as a result of the previous two. Likewise, the magnitude of the cost will largely depend on the degree of intelligence that is allocated on the strategy to implement the technology used in the detection and communication system.

Palavras-chave : Traffic flow; evolutionary algorithms; strategies of responsive control; sensible strategies of control to the traffic.
