## 3 Dataset Analysis
### Dataset Overview  
The description of the dataset is provided in Tables 2-5 by presenting several relevant statistics. The timespan is between 2002 and 2023, from 519 published sources--see Table 2. Within our dataset of 1127 documents, the majority have been published in recent years, resulting in notably low average years from publication of 4.96. This trend underscores the contemporary scholarly focus on the transportation domain and ABMs. Moreover, the average number of citations per document stands at 21.41, reflecting the increasing interest of the scientific community in these subjects. Notably, there is a substantial average of 2.906 citations per year per document, emphasizing the ongoing relevance of the research. However, it is important to note that the dataset comprises a substantial 45,200 references, with an average of 40.11 references per document. This underscores the depth and breadth of the literature informing the research within the transportation and ABM domains. The annual scientific production serves as a pivotal indicator, offering insights into the progression of research within the analyzed domain. Notably, this indicator reveals a noteworthy evolution over the examined timeframe (Figure 2). \begin{table}

Table 5: Authors’ collaboration. At the outset of our analysis, there is a discernibly scant number of papers. In 2002 and 2003, for instance, only two relevant articles are observed, and there is a dearth of such articles until 2008 (Figure 2). However, from 2008 onwards, a distinct upward trajectory emerges, culminating in 2021, where we observe a zenith with a total of 138 articles. This remarkable increase demonstrates an annual growth rate of 21.67%, attesting to the growing scholarly interest and productivity within the domain (Figure 2). The average article citations per year serves as an informative metric, highlighting a discernible positive trend spanning from 2002 to 2023 (Figure 3). The zenith in this metric was observed in 2008, with an average of 31.57 citations per article (Figure 3). However, it is noteworthy to acknowledge that this year represented an exception. Subsequent to this peak, in the following year, the average declined to 3.68 citations per article, which aligns closely with the overall average spanning the entire period. This fluctuation underscores the variable citation patterns within the domain, with 2008 presenting an anomaly amidst the broader trajectory (Figure 3). In the year 2008, the document identified as the most globally cited (authored by [PERSON] et al. [61]--as presented in Table 6) was published, accumulating a notable 5.5-fold citation advantage over the second-ranked document (3749 citations compared to 664 citations). In order to assess the impact of each article, the information provided in Figure 3 uses a specific metric named MeanTCperArt (mean total citations per article). As revealed in Figure 3, a substantial disparity between 2008 and subsequent years is observed, largely attributed to the influential paper authored by [PERSON] et al. [61].
