Walking and Cycling Seniors The most vulnerable road
Walking and Cycling Seniors The most vulnerable road users Heike Martensen Belgian Road Safety Institute
The risk of walking and cycling? ‣ Walking and cycling is good for all of us! ‣ Environment ‣ Condition ‣ Health ‣ What are the risks? How can we make it more safe? ‣ Data needs ‣ Crash data ‣ Hospital data ‣ Mobility data 1
@Risk ‣ Risk of severe injury (MAIS 3+) ‣ Risk per km travelled ‣ Relative to average car occupant Belgium 2007 -2011 2

The risk of walking and cycling? ‣ Large risks for ‣ Beginners ‣ Elderly ‣ Especially 75+ ‣ ‣ ‣ Motorcyclists Cyclists Pedestrians 4

The aging society – increasing mobility Seniors are a very heterogeneous group. Mobility is increasing. Source: GOAL, 2012 7
The aging society – crash statistics Number of elderly fatalities and percentage of all road fatalities, EU, 2005 -2014 Crash statistics reflect rising share of elderly people in society and transport. Source: ERSO 2016 8
Fatal crash victims in Belgium 900 Half of the elderly victims who died in traffic were pedestrians or cyclists.

Age related changes ‣ Safer ‣ More careful, more respect for rules ‣ Avoiding critical situations (rush-hour, darkness) ‣ Limitations ‣ Sight: sharpness, periphery, darkness, depth ‣ Attention: double tasking, overview, relevance ‣ Reaction time: perception, judgement, decision, execution. ‣ Flexibility: Head turns, balance, steadiness ‣ Vulnerability: Resistance, recovery ‣ Wide differences among elderly! 10
Pedestrian accidents ‣ 1 out of 3 pedestrians killed was falling (no vehicle involved) ‣ In Belgium not a “road traffic accident” ‣ Mostly elderly pedestrians ‣ For vehicle related crashes: ‣ 7 out of 10 was crossing road (elderly) ‣ Unsigned and zebra crossings ‣ Main causes: ‣ Misjudgement of vehicle speeds ‣ Overestiation of own walking speed Feypell, Papadimitriou, & Granié, 2010 ‣ Traffic density Dommes, Cavallo, Vienne, & Aillerie, 2012 Liu & Tung, 2014 ‣ Two sided traffic Ewert, 2012 11
Cyclist accidents ‣ 4 out of 10: no motor vehicle involved ‣ Seldom registered by police ‣ Main causes for elderly: ‣ Fall (-> 75+) ‣ Obstacle (-> 50+) ‣ Other cyclist (-> 50+) ‣ For vehicle related crashes: ‣ Crossings ‣ Turning left Nuyttens & Van Belleghem, 2014 Davidse et al. , 2014 Martensen, 2014 12
Accident with seniors ‣ More accidents at crossings ‣ Left turn (cars & cyclists) ‣ Crossing (Pedestrians) ‣ What’s going on? ‣ Complex situation ‣ Judgement distance & speed of others ‣ Perception of others in periphery. ‣ Balance & stability ‣ Why so serious? ‣ Physical vulnerability 13
What to do? ‣ Safe for elderly -> safe for everybody ‣ Overview ‣ Right angels ‣ Traffic from one side only ‣ Sight distance ‣ Lower speed
What to do? ‣ Maintenance ‣ Surfaces (potholes, slippery leaves, ice…) ‣ Avoidance of obstacles ‣ Curb
What to do? ‣ Data ‣ Falling pedestrians & cyclists are never/seldom registered by police ‣ Linking hospital and police data ‣ Including pedestrians falling into accident statistics? ‣ Other aspects can make elderly refrain from walking and cycling ‣ Darkness ‣ Fear of crime ‣ Need for detailed mobility data
Conclusion ‣ Walking & cycling is healthy! ‣ But … ‣ Walkers and cyclists have an increased risked for severe injuries ‣ Especially 75+ ‣ Half of elderly killed in traffic have been walking or cycling ‣ Making cycling & walking safer is a necessary precondition for promoting it – especially among seniors.
