Traffic Congestion

The National Performance Management Research Data Set (NPMRDS) and Application for Work Zone Performance Measurement

Transportation agencies are increasingly using probe vehicle data for transportation system performance management and as a resource for meeting the federal requirements of monitoring and reporting … [Read more...] about The National Performance Management Research Data Set (NPMRDS) and Application for Work Zone Performance Measurement

Fault-Tolerant Control of Variable Speed Limits for Freeway Work Zone Using Likelihood Estimation

Freeway work zone with lane closure can lead to disruption to local traffic and cause significant impacts on mobility, safety and environmental sustainability. To mitigate traffic congestion near work … [Read more...] about Fault-Tolerant Control of Variable Speed Limits for Freeway Work Zone Using Likelihood Estimation

Machine Learning Approach to Forecast Work Zone Mobility Using Probe Vehicle Data

The aim of deploying intelligent transportation systems (ITS) is often to help engineers and operators identify traffic congestion. The future of ITS-based traffic management is the prediction of … [Read more...] about Machine Learning Approach to Forecast Work Zone Mobility Using Probe Vehicle Data

Influence of Traffic Delay Produced During Maintenance Activities on the Life Cycle Assessment of a Road

This paper analyses the relevance of the traffic delay generated during the A-8 Spanish Motorway maintenance activities in order to make recommendations for inclusion within the LCA of roads. Six … [Read more...] about Influence of Traffic Delay Produced During Maintenance Activities on the Life Cycle Assessment of a Road

Evaluation of Interstate Work Zone Mobility Using Probe Vehicle Data and Machine Learning Techniques

According to the Federal Highway Administration (FHWA), US work zones on freeways account for nearly 24% of nonrecurring freeway delays and 10% of overall congestion. Historically, there have been … [Read more...] about Evaluation of Interstate Work Zone Mobility Using Probe Vehicle Data and Machine Learning Techniques

Practical Road-Resistance Functions for Expressway Work Zones in Occupied Lane Conditions

In order to create a practical road-resistance function for work zones under different lane occupation conditions, the expected speed of vehicles was calibrated in the work zone simulation model based … [Read more...] about Practical Road-Resistance Functions for Expressway Work Zones in Occupied Lane Conditions
