Evaluation of central town areas without pedestrian crossings

Areas in town centres without crosswalks are characterized by a special type of operation and appropriate design of the streets and streetscape. Pedestrians continually cross whole areas as opposed to bundled/grouped crossings at crosswalks. A first study of examples of town centres without crosswalks was conducted in a study commissioned by the Swiss Association of Transportation Engineers (SVI 2002/001). The aim of this evaluation is now to find out whether the first study’s positive findings on installations that were new at the time are still valid today, after having been in operation for a longer period, and to examine whether new streetscapes installed since the time of that first study are showing positive effects. With this longitudinal look, the suitability of areas without pedestrian crossings within town centres/on main roads will be evaluated in depth. Examples in other countries will also be included in the study.

Effect of Travel Recommendations

The aim of this research project is to develop a solution for standardized travel time information (for private transport) that supports drivers in their choice of routes and at the same time aids implementation of traffic management. Travel time information on variable message signs needs to be perceived and understood quickly by drivers. There should be as little distraction as possible from surrounding traffic. Standardizing the presentation of the information will allow fast perception due to a familiarization effect. As a result, road infrastructure managers will be able to achieve the best possible steering effect and at the same time to avoid endangering the safety of traffic participants unnecessarily.

Evaluation of the bicycle campaign Sicherheit hat Vortritt

On behalf of the Fund for Road Safety (FVS), a campaign to increase road safety for bicyclists was conducted in 2014-2016. What are the traffic psychology effects of this campaign on the target group? Based on evaluation criteria stemming from various constructs (traffic-related knowledge and attitudes, assessment of danger, etc.), this study aimed to produce relevant findings and in addition to contribute knowledge towards standardizing evaluation procedures for assessing traffic safety measures.

Subjective assessment of health risks taking hearing protection as an example

Loud music can damage hearing. This is something that most people in Switzerland are aware of – at least apparently. Nevertheless, the majority of people do not protect their hearing when at clubs or concerts. This can result in considerable damage to health, from tinnitus and temporary threshold shift to permanent, irreversible hearing damage. The aim of this study is to investigate individual cognitive reasons as to why people do not wear protective ear plugs. In particular, we aim to find out whether people subjectively view their objective health damaging behaviour as at all dangerous. Participants will be surveyed directly during concerts, in order to set subjective assessment in relation to real behaviour. The study is designed to show effective prevention approaches to hearing protection and risk behaviour, with the objective to increase the use of hearing protection over time and in this way prevent hearing damage.
