Understanding the relationships between road surface properties and high speed friction is key to managing the risk of loss of vehicle control. It is understood that, in wet conditions, texture depth ...

There has been much debate in the literature and elsewhere regarding cycle helmets and their potential to prevent injury. This cycle helmet safety research report was commissioned to provide a ...

Visually impaired pedestrians have reported problems with detecting the tactile central delineator used to separate cyclists from pedestrians on shared, segregated routes. This was reported to be due ...

This study aimed to assess the impact of interacting with two infotainment systems, Android Auto and Apple CarPlay, on four driver performance measures: reaction time, driving behaviour, eyes-off road ...

Currently, during automated vehicle trials there are two personnel present within each test vehicle: the Safety Driver and the Test Assistant. This summary report presents recommendations on how to ...

In England, Local Authorities provide network-level Road Condition Monitoring (RCM) data to the Department for Transport each year, so that the DfT can publish annual official statistics for road ...

The main aim of this study was to determine whether any real factors contribute to the exclusion of cyclists from some pedestrian areas. In these areas where cycling is permitted, it has been achieved ...

The asphalt Pavement Embodied Carbon Tool (asPECT) is a carbon footprinting tool for asphalt road pavements. It was first developed in 2009 as part of a programme of work funded by the collaborative ...

The report gives the findings of a study of accident risk based on a national stratified sample of 300 urban priority crossroads and staggered junctions on single carriageway roads (2917 personal ...

Road surface friction on the Strategic Road Network (SRN) is managed through the requirement to provide skid resistance and texture depth. The requirements have been in place since the 1980s and were ...
