Passing Segment Length Determination on Two-Lane Highways

open access: yesTransportation Research Procedia, 2017
Abstract Passing lane has been often constructed to dissipate traffic queues growing behind slow moving vehicles. These queues may appear randomly on a two-lane highway depending on geometry, traffic volumes, location and vehicle performance. For example, on the uphill side of a highway with relatively high AADT, a transient queue can rapidly grow ...

Using Non-Parametric Tests to Evaluate Traffic Forecasting Performance. [PDF]

open access: yes, 2002
This paper proposes the use of a number of nonparametric comparison methods for evaluating traffic flow forecasting techniques. The advantage to these methods is that they are free of any distributional assumptions and can be legitimately used on small ...

Collision prediction models with longitudinal data: an analysis of contributing factors in collision frequency in road segments in Portugal [PDF]

open access: yes, 2016
In spite of the strategic importance of the national Portuguese road network, there are no recent studies concerned with either the identification of contributory factors to road collisions or collision prediction models (CPMs) for this type of roadway ...

Virtual-MIMO-Boosted Information Propagation on Highways

open access: yes, 2015
In vehicular communications, traffic-related information should be spread over the network as quickly as possible to maintain a safer transportation system. This motivates us to develop more efficient information propagation schemes.

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 ...

Crash prediction model for two-lane rural highways in the Ashanti region of Ghana

open access: yesIATSS Research, 2011
Crash Prediction Models (CPMs) have been used elsewhere as a useful tool by road Engineers and Planners. There is however no study on the prediction of road traffic crashes on rural highways in Ghana.

Crossroads II: Marshall Report 996 [PDF]

open access: yes, 1999
Lake County, Illinois is already experiencing a traffic congestion problem. By the year 2020, when its population is projected to increase by at least 250,000, traffic congestion will likely be significantly worse.
