Exploring the effects of area-level factors on traffic crash frequency by severity using multivariate space-time models

Amin Azimian et al.

Summary: The study reveals positive associations between primary roadway density and all crash severities, as well as negative associations between intersection density and injury and no injury crashes. School density and rates of driving under the influence are positively associated with no injury crashes. Mean travel time to the hospital is positively associated with fatal crashes, while urbanity is negatively associated.

Exploring analytical, simulation-based, and hybrid model structures for multivariate crash frequency modeling

Tanmoy Bhowmik et al.

Summary: In safety literature, two methods are used to incorporate the potential correlation between multiple crash frequency variables: simulation-based approach and analytical closed-form approach. This research compares simulation-based multivariate models with Copula-based closed-form approaches for analyzing crash counts at the zonal level. The study introduces a hybrid approach that combines analytical and simulation methods, showing superior performance in fitting and predicting crash data compared to purely simulation-based models.

An accelerated hierarchical Bayesian crash frequency model with accommodation of spatiotemporal interactions

Haipeng Cui et al.

Summary: The study proposes a Bayesian spatiotemporal interaction (BSTI) approach for crash frequency modeling with an integrated nested Laplace approximation (INLA) method to expedite the Bayesian estimation process. In the study area of Manhattan, the BSTI model with Type II interaction is found to outperform others in terms of goodness-of-fit and the ability to reduce the dependency of residuals. The research also suggests that unobserved heterogeneity is mostly attributed to spatial effects instead of temporal effects.

Investigating the safety and operational benefits of mixed traffic environments with different automated vehicle market penetration rates in the proximity of a driveway on an urban arterial

Seyedeh Maryam Mousavi et al.

Summary: Traffic congestion is worsening in large cities due to rapid urbanization, causing concerns for road users. Autonomous Vehicles offer opportunities to improve traffic safety and operation. Increased market penetration rates of AVs can significantly enhance traffic density and reduce accident risks, especially in high traffic scenarios.

Spatial analysis of road crash frequency using Bayesian models with Integrated Nested Laplace Approximation (INLA)

Romi Satria et al.

Summary: The study developed an INLA-CAR model to assess crash severity on a highway section in Banda Aceh, Indonesia, and found that including spatial correlation in the model is important. AADT was identified as the most influential factor in both models and across all severity types, but the impacts of land use and horizontal alignment varied across severity types.
