Erratum for “Optimization of Synchronized Scheduling for Dual-Source Trolleybus Network”

The following corrections should be made to “Optimization of Synchronized Scheduling for Dual-Source Trolleybus Network” by Changfeng Zou, Ning Sun, Baoyu Hu, and Hongliang Li, https://doi.org/10.1061/JTEPBS.TEENG-7232:

In the “Computational Complexity” section, the first sentence incorrectly refers to Eq. (18); it should refer to Eq. (20). The corrected sentence follows:

It was assumed that $D_{d,i}^p$ is the departure time range of line $i$ trip $p$, as shown in Eq. (20).

In Table 14, the code of common stations was repeated as $b_1^2\text{-}{b}_{17}^2$. The revised table is included herein.

In the “Result of Case Study” section, the first paragraph in the “Analysis” subsection, the solution sets $S_3$ and $S_2$ were switched in the third sentence. The corrected sentence should read:

Comparing $S_3$ and $S_2$, on the premise of the same fleet size, $S_3$ has more synchronizations, and $S_3$ is better than $S_2$. Therefore, although $S_2$ is a feasible solution of the example, it is not used as a Pareto effective solution.

In Fig. 26, the solution sets $S_3$ and $S_2$ were switched in the original figure. The corrected figure is included herein.

In the “Sensitivity Analysis of Algorithm Parameters” section, the first sentence included the incorrect variable for crossover probability. The corrected sentence is as follows:

The two-stage algorithm mainly involves four parameters: population size (pop size), number of iterations (Gen), crossover probability ($P_c$), and mutation probability ($P_m$).

The description of what is included in Fig. 28 was incorrect. The correct description contained in the “Sensitivity Analysis of Algorithm Parameters” is as follows:

According to the above analysis, setting pop size = 150, Gen = 300, the results of using the two-stage algorithm with different crossover and mutation probabilities are shown in Fig. 28.

To preserve the published version of record, these details have been corrected only in this erratum.
