In the Netherlands, older cyclists run an increased risk of bicycle crashes. Critical factors are low-speed interactions, stopping, (dis)mounting, and potentially misjudging riding speeds. A Bicycle Light Communication System (BLCS) was therefore developed that displayed riding speed, braking, and turning intentions. In an experiment, 21 older and 20 younger cyclists observed BLCS-signals of a lead cyclist and estimated speeds of an approaching cyclist, with and without BLCS. Interviews were conducted to assess general opinions on BLCS and its influence on cycling behaviour.In a small follow-up study, twelve older cyclists used a BLCS-bicycle one week to explore first user-impressions. The majority evaluated the BLCS positively, mainly the turning indicator and brake light components, even though interpreting the speed signals was difficult. Although the first userimpressions revealed that the direction indicator does not influence selfreported balance (positively or negatively), the majority reported that they would like to use a BLCS themselves.

It is therefore meaningful to study the effects of ageing and the factors that make older cyclists vulnerable in order to increase the safety of older cyclists and prevent crashes and injuries, which is also a priority of the Dutch government (Rijkswaterstaat, 2016).Crash statistics in the Netherlands indicate that after a decline for many years, the number of fatal traffic crashes has increased by 10.6% from 2017 to 2018 (CBS, 2019). This increase also included cyclists and relatively many older cyclists are seriously injured due to a bicycle crash, also outside the Netherlands (OECD/International Transport Forum, 2013). Exact statistics concerning bicycle crashes are limited as bicycle crashes with a relatively minor outcome are not or less often officially reported than crashes with a severe outcome (Juhra et al., 2012;Wegman, Zhang, & Dijkstra, 2012;Schepers, 2013). It is estimated that a large proportion of these crashes are Single-Bicycle Crashes (SBCs): crashes where no other road user is involved (Schepers et al., 2015). In 2016, the majority of SBCs in the Netherlands concerned a loss of balance while cycling (62%) or while getting on or off the bicycle (10%), and 17% collided with an object or a person (VeiligheidNL/Rijkswaterstaat, 2017). Schepers and Klein Wolt (2012) in their literature review found that the majority of SBCs could be divided in infrastructure-related and cyclist-related crashes. Infrastructure-related crashes occur due to the condition of the road surface or the impact caused by an object. In approximately 50% of the SBCs they investigated, the infrastructure was a significant contributor to the cause of the crash (Schepers, 2008;Schepers & Klein Wolt, 2012). Older cyclists are particularly involved in crashes related to narrow bicycle facilities, entering the verge, or colliding with objects or bollards (Schepers, 2008). The SBC-category of cyclist-related accidents concerns crashes due to the cyclist losing control over the bicycle. This might occur, for example, while mounting or dismounting the bicycle, while cycling at low speeds, or when making mistakes or misjudgements (Schepers & Klein Wolt, 2012).Although the term SBC basically implies that no other road user was directly involved in the crash, this does not mean that there was no influence of another road user on the occurrence of the crash at all (VeiligheidNL/Rijkswaterstaat, 2017). Indeed, recent studies indicated that SBCs may also be related to the behaviour of another road user or could be preceded by an interaction with another road user (Boele-Vos et al., 2017). It is possible, for example, that an approaching cyclist leaves little room for other cyclists and that someone therefore has to change course to prevent a collision and subsequently falls down due to hitting a kerb or an object. Although strictly defined this would be registered as a SBC, it was the behaviour of another road user that triggered the chain of events that eventually ended with a crash. 1 12 Chapter 1value for themselves, preferably as quick a...
