A new, non-canonical Poisson regression model for the prediction of crashes on low-volume rural roads

open access: yesIATSS Research, 2012
The purpose of the study was to compare the prediction power of a simplified non-canonical Poisson crash-prediction model to other model types. The model, fitted to serious and fatal crash data from 86 two-lane low-volume rural highway segments, showed a

Approximation of time headway on two-lane highways using test car approach [PDF]

open access: yes, 2014
Time headway is an essential variable in various traffic engineering applications such as capacity and level of service (LOS) analyses of road segments and intersections, traffic safety analysis, generation of vehicles in microscopic simulations, and so ...

A Cellular Automaton Model for the Traffic Flow in Bogota

open access: yes, 2004
In this work we propose a car cellular automaton model that reproduces the experimental behavior of traffic flows in Bogot\'a. Our model includes three elements: hysteresis between the acceleration and brake gaps, a delay time in the acceleration, and an

Portuguese two-lane highways: modelling crash frequencies for different temporal and spatial aggregation of crash data

open access: yesTransport, 2018
The identification of contributory factors to crash frequencies observed in different highway facilities can aid transportation and traffic management agencies to improve road traffic safety.

An Empirical Model for Optimal Highway Durability in Cold Regions [PDF]

open access: yes, 2016
We develop an empirical tool to estimate optimal highway durability in cold regions. To test the model, we assemble a data set containing all highway construction and maintenance projects in Arizona and Washington State from 1990 to 2014.

Public Perceptions of the Midwest’s Pavements: Policies and Tradeoffs in Pavement Improvement [PDF]

open access: yes, 2004
With the budget crisis plaguing so many states, pavement management will compete more vigorously for limited funds. Findings reported from a tri-state pooled-fund research project provide insights and guidelines for pavement improvement derived from the ...
