(iii) Thorough analysis and comparison of the different traffic light programs for the Malaga city case study: these cycle programs were generated as candidate solutions by means of four optimization algorithms: PSOTL, DETL, RS, and SCPG (human experts' solutions).
DETL. This algorithm also performs a population-based search, but following in this case the operation scheme as specified by the Differential Evolution algorithm (version DE/rand/1) [44].
As described in Section 3, given an urban scenario related to a certain area in a real city, the cycle programs of traffic lights operating in this area are optimized by means of several specialized algorithms: PSOTL, DETL, RS, and SCPG, described in Section 3.3.
As stated in the introduction, we include a varied analysis including four specialized algorithms for computing cycle programs of traffic lights: PSOTL, DETL, RS, and SCPG.
In this regard, we can see that PSOTL is significantly different to RS for all the scenarios (thus, an intelligent algorithm is needed), whereas solutions provided by DETL are not statistically different to the ones provided by the human experts, represented in SCPG (so DETL is just equivalent to the expert's solutions, not better).
Numerically speaking, these cycle programs (the ones generated by PSOTL) are better than the ones provided by DETL, RS, and SCPG by 79.01%, 71.29%, and 83.03%, respectively.
