Highlights: [•] Residence characteristics of drivers who caused traffic crashes were investigated. [•] Bayesian Poisson-lognormal model was adopted in this study. [•] Population and commute mode were related with the number of at-fault drivers. [•] Age, commute time, and income were associated with the number of at-fault drivers. [•] Findings from the study can identify residence areas with risky drivers. [Copyright &y& Elsevier]

To convert HOV (high-occupancy vehicle) lanes to HOT (high-occupancy toll) lanes, it is necessary to evaluate the relevant benefits to drivers, to highway maintenance, to traffic management, and to the whole society under various combinations of tolls, motorists’ perception error, and travel demand. This paper assesses the benefit and effect of an HOV/HOT lane project on the I-394 corridor network in the Twin Cities by using an analytical multiclass stochastic dynamic transportation network model with Monte Carlo simulation and the method of successive averages. Specifically, the effects of various toll schemes for HOT lane design and operations are investigated. The results are analyzed, yielding useful insights for the design and evaluation of HOT lanes.

Car-following models, which describe the reactions of the driver of a following car to the changes of the leading car, are essential for the development of traffic flow theory. A car-following model with a stochastic memory effect is considered to be more realistic in modeling drivers’ behavior. Because a gamma-distributed memory function has been shown to outperform other forms according to empirical data, in this study, we thus focus on a car-following model with a gamma-distributed memory effect; analytical and numerical studies are then conducted for stability analysis. Accordingly, the general expression of undamped and stability points is achieved by analytical study. The numerical results show great agreement with the analytical results: introducing the effect of the driver’s memory causes the stable regions to weaken slightly, but the metastable region is obviously enlarged. In addition, a numerical study is performed to further analyze the variation of the stable and unstable regions with respect to the different profiles of gamma distribution. [ABSTRACT FROM AUTHOR]
