In this work, a model of an automated traffic light
controller (ADS - 3G) had been designed, simulated, tested
and implemented, using experimental techniques in electronic
engineering, to manage the traffics at the busy four way
junctions along Sahuda road in Mubi North Adamawa State,
Nigeria. The designed was achieved with the help of 12V
automated solar energy power supply, time base (555 timer),
decade counter, D-flip-flop, timing sequence selector for
red, green, amber and yellow light and relay circuit for
switching the appropriate light. The average volume of
vehicular traffics observed for the period of one week
(4/4/07 - 11/4/07) for Masalachi, Stadium, Sahuda and Sarki
roads are 2368, 1996, 1982 and 138, respectively which
prompted the development of the model (ADS - 3G) to allowed
17.50, 14.00, 10.50 and 7.00 s accordingly. This model is
capable of eliminating the inefficiency and likely error
associated with human traffic controller by minimizing
accident and unnecessary traffic jams at the junction.
Key words: Solar energy, traffic jam, traffic flow,
traffic light controller and human traffic. |
