Data quality management related to road infrastructure condition and safety

When doing safety and accident studies related to road surface characteristics the quality of the used data are of extreme importance. The definition, the techniques and strategy of collection of both condition as accident data can differ a lot between and within countries. An example of such confusion is the data considering pavement friction and skid resistance. In Europe currently more than 15 measuring devices for skid resistance are covered in the CEN standards. The availability of enough friction is the most essential road characteristic for safety issues. Other examples is the use of expressions of road condition such as rut depth. No standard exist and different calculations are used implying that they need careful consideration before exchange of accident analysis results are done. Most road surface indicators are developed for indication of road wear, not accident analysis. The Road Administration in Sweden have paid attention to this and made a number of actions to improve the quality of data. There are many quality aspects on data and data collection such as reliability, robustness, suitability for the purpose (relevant), performance, safe to collect, easy to maintain and costs. This presentation will present some actions and quality improvements for data and data collection that has been done in Sweden.

Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.



The five-year anniversary of European Road Profile Users' Group (ERPUG) Forum will take place at Ramboll head quarter, Copenhagen, Denmark October 19-20, 2017.


Self-driving buses in Sweden next year?

A self-driving, fossil-free bus. This idea might become reality through a forthcoming collaborative project involving the Swedish National Road and Transport Research Institute (VTI), Linköping University and several other participants. The project group aim...


New climate-proof solutions for hard surfaces in cities

High-density road infrastructure that emphasise maximum durability and minimum maintenance create inflexible systems, which put increased stress on urban trees and lead to increased risk for flooding. Over the past five years, the ‘Climate-proof solutions for...


VTI is preparing for automated vehicles

Automation of traffic systems will lead to major changes. The European Union’s (EU) CoEXist research project began in June 2017 with the aim of preparing cities and road operators for the introduction of self-driving vehicles. The Swedish National Road and...


Vehicle Driver Monitoring: sleepiness and cognitive load

To prevent road crashes it is important to understand driver related contributing factors, which have been suggested to be the critical reason in 94 per cent of crashes. The overall aim of the project Vehicle Driver Monitoring has been to advance the...
