State awareness, risk awareness of and calibration by road users : a literature study.

In addition to the three original principles for a sustainably safe traffic system, two new principles have been introduced in Advancing Sustainable Safety (Wegman & Aarts, 2005) – (social) forgivingness and state awareness. In the following years, these principles have been defined in more detail. This report provides a comprehensive explanation of the term state awareness and the role it plays in safe traffic participation. Houtenbos (2009) has further elaborated the principle of social forgivingness. This report may be accessed by Internet users at: http://www.swov.nl/rapport/R-2010-02.pdf
