Monte Carlo-Based Microsimulation Approach for Estimating the Collision Probability of Real Traffic Conflicts

During driving in real traffic, often conflict situations arise which do not lead to an accident; however, they offer a good indication of traffic (un)safety. There are many methods and indicators for classifying whether a current driving situation can be considered as a conflict or not (e.g., time to collision, post-encroachment time). However,...

The Weakness of Robustness

Cross-comparison of three surrogate safety methods to diagnose cyclist safety problems at intersections in Norway

Relying on accident records as the main data source for studying cyclists’ safety has many drawbacks, such as high degree of under-reporting, the lack of accident details and particularly of information about the interaction processes that led to the accident. It is also an ethical problem as one has to wait for accidents to happen in order to...

Een nieuwe veiligheids filosofie voor een Secure Haven

Security Haven is een tweejarig onderzoeksproject op het gebied van innovatie aan infrastructuur en de daarbij betrokken wet en regelgeving, dat in juni is afgerond. De kerngedachte achter het project is veiligheid en comfort te combineren voor zowel stad als mens. De gemeente Den Haag is er veel aangelegen de status van internationale stad te...

Development of a micro-simulation model to predict road traffic safety on intersections with surrogate safety measures

This paper describes an ongoing research project at TNO in the Netherlands for assessing the safety of road networks using micro-simulation techniques. A benefit of micro-simulation comes from the ability to evaluate the safety of new ITS systems, new infrastructure design, management strategies and different traffic compositions beforehand. The...

Layer of protection analysis: Selecting cost effective safety measures

Traditionally, in process industry risks are reduced by applying technical solutions and taking organisational measures. The performance of both types of 'solutions' depends on many factors and can not easily be compared. Especially the effectiveness of organisational measures such as the use of procedures, education, training and improving the...
