Traffic Speed

Analysis of Headway and Speed Based on Driver Characteristics and Work Zone Configurations Using Naturalistic Driving Study Data

The objective of this paper is to analyze headway and speed distribution based on driver characteristics and work zone (WZ) configurations by utilizing Naturalistic Driving Study (NDS) data. The NDS … [Read more...] about Analysis of Headway and Speed Based on Driver Characteristics and Work Zone Configurations Using Naturalistic Driving Study Data

Speed Variation and Safety in Work Zones

In addition to lower speeds, the difference between vehicle speed and the average speed on the roadway has been identified as a factor in roadway crashes. For work zones, the potential for such speed … [Read more...] about Speed Variation and Safety in Work Zones

Queue Analysis at Work Zones From Field-Collected Data

Estimation of the capacity of work zones is vital to manage the possibility of traffic flows exceeding capacity and resulting in unbearable queues during work zone lane closures. A plethora of … [Read more...] about Queue Analysis at Work Zones From Field-Collected Data

A Deep Machine Learning Approach for Predicting Freeway Work Zone Delay Using Big Data

The introduction of deep learning and big data analytics may significantly elevate the performance of traffic speed prediction. Work zones become one of the most critical factors causing congestion … [Read more...] about A Deep Machine Learning Approach for Predicting Freeway Work Zone Delay Using Big Data

Evaluation of the Effectiveness of Dynamic Speed Feed Back Signs in Work Zones on High-Speed Kansas Roadways

Work zones are essential to keeping our roadways preserved or reconstructed so that they are safe and efficient. Work zones tend to increase safety risks due to the normal driving’s changing … [Read more...] about Evaluation of the Effectiveness of Dynamic Speed Feed Back Signs in Work Zones on High-Speed Kansas Roadways

Modelling of Queue Length in Freeway Work Zones – Case Study Karaj-Tehran Freeway

In this study, the traffic parameters were collected from three work zones in Iran in order to evaluate the queue length in the work zones. The work zones were observed at peak and non-peak hours. The … [Read more...] about Modelling of Queue Length in Freeway Work Zones – Case Study Karaj-Tehran Freeway
