Major and minor disturbances can have a considerable impact effect on the performance of road networks. In this respect, resilience is considered as the ability of a road section to resist and to recover from disturbances in traffic flow. In this contribution an indicator is presented, the Link Performance Index for Resilience (LPIR), which evaluates the resilience level of individual road sect...

The development of performance metrics is critical in the evaluation and advancement of intelligent systems. Obtaining the pinnacle of intelligence in autonomous vehicles requires evolutionary standards and community support. In order to analyze and compare competing implementations of intelligent systems, the critical components of the system must be decoupled to facilitate repeatable trials t...

Bridge condition assessment in most European countries is based on visual inspection combination with damage of bridge components. For adequate management, the needs to be further developed move from component level system functionality and finally priority ranking for repairs network. Although provides only qualitative insights into cannot predict load-carrying capacity, it still very often wa...

OBJECTIVE To examine if HIV-seropositive (HIV+) individuals are at risk for impaired driving. METHODS Sixty licensed drivers (40 HIV+, 20 HIV-) completed a neuropsychological (NP) test battery and driving assessments. Eleven HIV+ subjects were NP-impaired. Driving-related skills were assessed using 1) two driving simulations (examining accident avoidance and navigational abilities), 2) the Us...

The main objective of this study was to determine if a minimal increase in road light level (luminance) could lead to improved driving performance among older adults. Older, middleaged and younger adults were tested in a driving simulator following vision and cognitive screening. Comparisons were made for the performance of simulated night driving under two road light conditions (0.6 and 2.5 cd...

Driving Decision-making Mechanism (DDM) is identified as the key technology to ensure the driving safety of autonomous vehicle, which is mainly influenced by vehicle states and road conditions. However, previous studies have seldom considered road conditions and their coupled effects on driving decisions. Therefore, road conditions are introduced into DDM in this paper, and are based on a Suppo...

Road safety performance indicators are comprehensible tools that provide a better understanding of current safety conditions and can be used to monitor the effect of policy interventions. New insights can be gained in case one road safety index is composed of all risk indicators. The overall safety performance can then be evaluated, and countries ranked. In this paper, a promising structure of ...
