Nearly 1.3 million people die in road crashes each year, on average 3,287 deaths a day. In 2013 in the European Union more than 6 % of all who died in road traffic crashes were cyclists. The number of cyclist killed on roads in the EU has decreased by only 9 %, compared to the total fatality decrease of 18 % from 2010 to 2013. The majority of cyclist fatalities are males (78 %). For the larger countries, Belgium and The Netherlands had the highest proportion of female cyclist fatalities (> 30 %). In general, 55 % of the bicycle fatalities in the EU countries were killed inside urban areas but there are large differences between the countries. In the last couple of years there has been an enormous effort on reduction in cycling fatality numbers across almost all ages in the EU. As a result of this effort, the number of accidents started to slightly decrease. This paper reviews the literature concerning cyclist-motor vehicle collision and road safety management according to the cyclist role in the accident rise. The paper examines pedestrians safety in order to determine what kind of factors of transport infrastructure, vehicle technical parameters, cyclist behavior and road or street category have the influence on cyclist and vehicle accidents and identify technical reasons of the accidents rise. A review is conducted of information in the literature on the injury outcome of a cyclist/vehicle collision for a given impact speed and the likely consequences of reducing the travelling speeds of vehicles in terms of the frequency and severity of cyclist injuries.

“…Limiting or removing roadside objects increases the forgivingness of a road because obviously a road user cannot collide with these anymore but they can often also return to the road safely (Wegman, Aarts, and Bax 2008). Since it is not always possible to remove such objects, their visibility can also be increased by changing colour, increasing contrast, or adding delineation (Schepers and den Brinker 2011;Fabriek, De Waard, and Schepers 2012).…”

Cycling on the edge: the effects of edge lines, slanted kerbstones, shoulder, and edge strips on cycling behaviour of cyclists older than 50 years

To prevent single-bicycle crashes, this study is the first to evaluate effects of slanted kerbstones, edge lines, shoulder strips, and edge strips on cycling behaviour of cyclists !50 years. In Experiment 1, 32 participants cycled on a control path and paths with edge lines, slanted kerbstones, and three types of 0.5 m wide shoulder strips (with grey artificial grass, green artificial grass, or concrete street-print). In Experiment 2, 30 participants cycled a different route including a control path and paths with edge lines or 0.3 m white edge strips. Cyclists rode closer to the main cycle path's edge in the shoulder strips conditions, although the presence of these strips resulted in a larger total distance to the verge compared to the control condition. Furthermore, cyclists cycled further from the verge in the edge strip condition than the control condition. Safety implications of the shoulder and edge strips are considered to be positive.

“…Although minor cycling accidents in the Netherlands are underreported (Schepers & Klein Wolt, 2012;Wegman, Zhang, & Dijkstra, 2012), estimations are that in more than 60% of all cyclist accidents leading to injuries no other traffic participants are involved (Schepers, 2013). In 50% of all single-sided accidents, infrastructural factors are of influence (Schepers & Klein Wolt, 2012;Schepers & den Brinker, 2011;Fabriek, De Waard, & Schepers, 2012) and 33% of these accidents happen on a cycle path (Schepers, 2008). Westerhuis and De Waard (2016) studied the behaviour of older cyclists in a naturalistic cycling setting and identified behaviour potentially leading to an accident.…”

An important factor in single-sided accidents of older cyclists is that they ride off the cycle path onto the verge. Two experiments were performed to assess the feasibility of using virtual 3D objects in the verge to affect the lateral position of bicyclists. In the first experiment, different virtual objects were placed in the shoulder and 1150 passing bicyclists were observed using a fixed camera. The (standard deviation of the) lateral position and speed in four conditions with virtual objects differing in colour, structure, or 3D effect were compared with a control condition in which no virtual objects were applied. In a second experiment, the behaviour of 32 bicyclists aged 50 years or older was measured by mounting two digital action cameras with GPS on the participants' bicycles. The participants cycled a route of approximately 12 km in which several locations were passed, one of these contained 15 virtual objects similar to the ones used in the first experiment placed in the shoulder of the cycle path. Cyclist behaviour was compared with behaviour at a control location consisting of a solitary twoway cycle path with a grass shoulder. Results indicate that the virtual objects in the tested format had little overall effect on cyclists' behaviour. However, bicyclists were positioned closer to the virtual objects and the shoulder when they looked at the objects or when they reported that they saw them while cycling. This suggests that the overall visibility of the object design may have been too conservative.
