Opportunities and barriers for measuring traffic safety indicators based on vehicle sensor data: A Delphi Study

Current indicators for measuring traffic safety such as fatalities and severe injuries are lagging indicators, meaning that an accident first needs to happen before it can be measured. With the rise of automation in vehicles, the opportunity may arise to measure leading indicators. These can proactively measure traffic safety by measuring...

Multi-leader Adaptive Cruise Control Systems considering Sensor Measurement Uncertainties based on Deep Reinforcement Learning

Adaptive Cruise Control (ACC) relieves human drivers’ tasks by taking over the control of the throttle and braking of the vehicles automatically. However, it has been demonstrated in many empirical studies that current production ACC systems fail to guarantee string stability. It is believed that if vehicles can take the longitudinal dynamics...

Identifying and testing the Operational Design Domain factors of Lane Keeping System at horizontal curves using PreScan

The European Commission has mandated the requirement of advanced safety features in all vehicles sold in the EU from 2022 onwards. This will help drivers get gradually used to ADS, eventually transitioning to fully autonomous driving in the distant future. There are more vehicles on road now equipped with lane-keeping systems and other driver...

Promoting Road Safety Between Automated Vehicles and Cyclists

Interacting with cyclists is a difficult challenge for Automated Vehicles (AVs). It is important that the introduction of AVs does not lead to a decrease in cyclist safety. This study presents a new methodology that is developed to assess road safety between AVs and cyclists. Surrogate Measures of Safety are identified specifically for the...

Analysing Mobility Hubs using Microsimulation Travel Demand Model: The case of OCTAVIUS

The traditional transport hubs are shaping into the idea of the mobility hubs with the advent of multiple vehicle-sharing forms, such as bike-sharing and car-sharing. Also, a gradual shift in the culture of consumption towards more usage and less ownership, as well as the shared economy supported by internet platforms and mobile apps, allows...

Exploring preferences in the Netherlands for MaaS mobility packages, as a transportation alternative for short-distance trips: A Stated Preference Experiment: Mobility as a Service

Cities of the Netherlands are the driving forces to develop and encompass a cluster of markets that boost productivity. In recent times, cities have tended to demonstrate the rapid transformation, more spatially dispersed and growing in demand for transportation. Reasonably, all the trips done intra-city are short-distance trips (i.e. trips less...

Booking and Payment Integration of Air- and Public Transport for First/Last Mile Airport Trips: A Conceptual Framework and Business Model Canvas

In this research, the link between air travel and the first/last mile trip with public transportation will be researched, as in practice, ticket platforms (such as Booking.com or Expedia) do not yet provide this integrated air- and public transport service. Eventually, the idea would be to create an integration platform that serves as a mediator...
