“…Anastasopoulos [42] developed a random parameter multivariate Tobit model to account for the unobserved heterogeneity of collision injury rates by severity. Other research also developed a random parameter multivariate Tobit model to analyze the crash rate by injury severity and found significant heterogeneous effects of estimates which varied across observations [43,44]. Guo et al [45] modeled the correlation and heterogeneity in crash rates by different collision types by developing a random parameters multivariate Tobit model.…”

“…The number of accidents that have occurred at individual tram stops are relatively rare. But at the same time, emergencies arise in which people who cross the carriageway to tram stops may suffer [17,18]. Conflict situations between pedestrians walking to a tram stop and vehicles usually arise when pedestrians cross the carriageway.…”

“…Since then, this approach has been applied to many research domains, such as medicines [42], social science [43], and especially in the safety analysis domain [44][45][46][47]. The incorporated spatial and temporal effect terms in the Bayesian spatiotemporal models "borrow strength" from neighboring locations and contiguous time periods to better accommodate the data [48,49]. Compared to the trained spatiotemporal features in the machine learning approaches, the Bayesian statistical approaches usually specify a structure for the spatial and/or temporal effect terms, which would greatly increase the interpretability of the results [50].…”
