Road safety performance indicators for the interurban road network

Accident Analysis and Prevention, 2013
Various road safety performance indicators (SPIs) have been proposed for different road safety research areas, mainly as regards driver behaviour (e.g. seat belt use, alcohol, drugs, etc.) and vehicles (e.g. passive safety); however, no SPIs for the road network and design have been developed. The objective of this research is the development of an SPI

Is road safety management linked to road safety performance?

Accident Analysis and Prevention, 2013
This research aims to explore the relationship between road safety management and road safety performance at country level. For that purpose, an appropriate theoretical framework is selected, namely the 'SUNflower' pyramid, which describes road safety management systems in terms of a five-level hierarchy: (i) structure and culture, (ii) programmes and ...

Modeling road-cycling performance

Journal of Applied Physiology, 1995
This paper presents a complete set of equations for a “first principles” mathematical model of road-cycling performance, including corrections for the effect of winds, tire pressure and wheel radius, altitude, relative humidity, rotational kinetic energy, drafting, and changed drag.

Awareness of Deficits and On-Road Driving Performance

The Clinical Neuropsychologist, 2011
This study examined the relationship of neuropsychological and on-road driving evaluations among adults with acquired brain injury (ABI), and the extent to which that relationship is moderated by awareness of deficit. Participants were 62 pairs of adults with ABI and significant-other informants and 40 healthy controls (N = 102).

Predicting the performance of automatic road detection

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
We introduce a methodology to predict the performance of road detection based on the ridge detector. The method is based on measured image statistics of the road and its immediate surroundings. It predicts the performance of the detection as well as the optimal parameter set which is needed for this detection.

On the Road to Improved Performance

Public Performance & Management Review, 2006
The rationale behind performance measurement requirements at all levels of government has to do with changing the way budget decisions are made. Supporters of performance measurement requirements argue that the use of performance measures will enhance, or even change, the way that budget discussions and subsequent decisions are made.

A Road Map For Improving The Performance Of Performance Measures

Health Affairs, 2011
The desire to improve the quality of health care has prompted the increased use of performance measures. These measures examine the outcomes of interventions for evidence of improved health and are used to hold providers accountable for the quality of health care.

Performance of geosynthetics in unpaved roads

International Journal of Geotechnical Engineering, 2010
AbstractThis paper presents results of field studies on unpaved low volume roads constructed over weak subgrade using geosynthetic reinforcement. The relative advantages of placing different reinforcing materials like geotextile, biaxial or uniaxial geogrid, geocell layer and tire shreds at the interface of subgrade and base course are studied in terms

Boosting performance of road infrastructure

Built Environment Project and Asset Management, 2011
PurposeSingapore's land transportation is governed by a comprehensive set of rules, regulations, operations and systems to ensure its effectiveness and efficiency. The Land Transport Authority (LTA) is the main agency in charge of road operations. Despite the LTA's best efforts, road related problems still surface every now and then.

Deicing Performance of Road Salt

Transportation Research Record: Journal of the Transportation Research Board, 2014
This paper describes the results of a field study designed to quantify the effects of various factors on the snow-melting performance of salt. Many tests were conducted in a realistic environment over two winter seasons, covering more than 70 snow events, with temperatures ranging from −14°C to 3°C and snowfalls ranging from ∼0.2 to 21.0 cm.
