i translated the description from spanish to english and this is the result: A Figure 4.74 shows the crossing of a rodovia as an access route. Vehicle detection sensors are placed along tracks C and D (in the road) and on tracks A and B (access route). As seen from these sensors, it will be LOW (0) level when no vehicle is present and HIGH level (1) when there is some current. Or traffic signal not crossing and controlled according to the following logic: 1. O sinal da direção leste-Oeste (L-W) will be green when both tracks C and D are occupied. 2. O sinal da direção leste-Oeste will be green whenever the C or D runways are occupied, plus those A and B are unoccupied. 3. O sinal da direção norte-sul (N-S) will always be green as long as both tracks A and B are occupied, plus C and D are unoccupied. 4. The north-south direction will also be green when tracks A or B are occupied while both tracks C and D are empty. 5. The east-west direction will be green when no vehicle is present. Using the two outputs A, B, C and D as inputs, project a logic circuit to control or semaphore. There must be two outputs, N-S and L-W, which will be HIGH level when the corresponding light is green.
