Service-life Pavement Performance Simulation: Capturing the Influence of Traffic Flows by Big Data Analysis

An ideal road management system requires a real-time assessment of pavement performance. But there are many root causes of the status quo that the expectation and the system have not been achieved yet. One of them is the monitoring system. In the Netherlands, the measurement is carried out once a year because of the budget and also because it is...

Safety assessment of the interaction between an automated vehicle and a cyclist

The operation of automated vehicles in shared areas requires attention with respect to the interaction between AVs and vulnerable road users, including cyclists. Currently, the programmed interaction behavior of AVs is based on the knowledge of the interaction between conventional vehicles and cyclists. However, cyclists may react differently to...

Road Infrastructure Requirements for Improved Performance of Lane Assistance Systems

There is a pressing need for road authorities to take a proactive role in the deployment of automated vehicles on the existing road network. This requires a comprehensive understanding of the road infrastructure requirements that would lead to safe operation of automated vehicles. In this context, a field test with Lane Departure Warning and...

A methodology for the assessment of Operational Design Domain of Lane Keeping Assistance system equipped vehicles: The case of Tesla Model S

In this research, a methodology to assess the Operational Design Domain of Lane Keeping Assistance System equipped vehicles is developed. The method is mainly intended for use by manufacturers of semi-automated vehicles to assess the situations and conditions in which their lane keeping systems that are already available in the market, can and...

Increasing speed limit compliance in motorway work zones: A human system integration approach

Speeding in motorway work zones lowers the perceived safety of road workers and increases the accident risks of traffic participants. In a work zone, traffic participants share the road with road workers. Road workers are often vulnerable and feel threatened by vehicles passing with high speed. Traffic participants are also at risk since driving...

A Potential New Structural Design for Flexible Pavement

Throughout the history of pavement structure, the parallel layer structure has dominated the structural design of pavements. In other words, the entire road pavement share a uniform thickness design regardless how many lanes there are. However, due to traffic regulations and driving habits, the traffic flow most probably does not distribute...
