An Assessment of the Evidence

A traffic safety problem arises for society if travelers fail to make good decisions. Sufficient incentive, information and competence must exist for 

Regardless of incentives and information, travelers must be sufficiently competent to make good decisions. The belief that individuals are incompetent to make risky decisions arises from research on behavioral decision rules in complex situations and on attitudes. Traffic safety dedsions are suspect because risks may be misperceived and expected safety benefits may be undervalued. Ola Svenson and his colleagues, for example, report based on their attitudinal study that subjects show optimism bias they feel they are more skillful and safer than typical drivers. They state that drivers who feel immune may discount measures such as seat belts. A sununary of this and other representative evidence of representative incompetence is presented in column 2 of Table 2-1. Next to these results, in column 3, is the evidence of competence for each subject natural hazards and insurance, gambling, risk perception, and safety belt use. 

My first conclusion is that the individual benefit-cost approach is highly useful for understanding traffic safety behavior and for thinking about traffic safety policy. The framework is general enough to incorporate the technolo cal and risk homeostatic approaches as special cases. My second conclusion is that roadway users are sufficiently competent and their safety

Following an assessment of the criteria in Table 3.2 it may become evident that there is only one viable route, but more probably two or three options will be difficult to choose between. In this case the alternatives should be screened experimentally to refine the data in Table 3.2 and to complete a pro-forma similar to that shown in Table 3.3. 

Thus, an assessment of the present situation would suggest, on balance, that experimental evidence appears to support the Radical Mechanism over the Carbocation Mechanism, although a number of important questions remain far from being resolved.

Commercial and public transportation heavily relies on human operators. There is growing evidence that sleep loss may play a large role in transportation accidents. A committee formed at the 1986 meeting of the Association of Professional Sleep Societies found that numerous performance failures leading to catastrophic events occur most often at times of day coincident with the temporal patterns of brain processes associated with sleep (3). In addition, an investigation in the Netherlands showed that the highest accident rate in public transit accidents occurred in bus drivers who began an early work shift (4). An assessment of the impact of sleep loss in commercial and public transportation is therefore needed. 

Gas vans are mentioned in numerous publications among the subject literature, but their existence is never examined critically or even questioned. The state of subject research was outlined most recently by Mathias Beer.1 We shall refer to this summary on occasion. Unfortunately, space limitations preclude an analysis of the general thesis we must restrict ourselves to touching on those points which, in our view, require closer examination in the present context, which has as its purpose the critical assessment of the evidence in the issue of the gas vans . 

This was indeed an alarming state of affairs, since in this age of illustrated magazines and television, photographs have a powerful pedagogic influence on the people, and faked photos therefore have a propagandistic and even incendiary effect that can hardly be overestimated. This is particularly so in the context of the National Socialist persecution of the Jews, as this is a topic for which the vast majority of the people have by now acquired a sort of Pavlovian response, a ritualistic consternation that renders any critical assessment of the evidence presented virtually impossible. 

The validation plan should require an assessment of the project success, and the validation report should present, or refer to, the evidence to support this. It is normally the case with a BMS project that the documentation is too large to attach to the report. It is, therefore, sensible to present the documentation in a list form with the location of each document referenced. This report must also clearly state that the system is validated and is approved by the user and Quality Assurance (QA). 

Classification is made on the basis of the appropriate criteria, outlined above, and an assessment of the total weight of evidence. Classification as a reproductive toxicant is intended to be used for chemicals which have an intrinsic, specific property to produce an adverse effect on reproduction and chemicals should not be so classified if such an effect is produced solely as a non-specific secondary consequence of other toxic effects. 

The role and status of a textbook. If a book is to be a useful guide to drug use it must offer clear conclusions and advice. If it is to be of reasonable size, alternative acceptable courses of action will often have to be omitted. What is recommended should be based on sormd evidence where this exists, and on an assessment of the opinions of the experienced where it does not.
