Causes of road casualties ROAD ENVIRONMENT Britains most dangerou s roads 4 ROAD ENVIRONMENT Worst road. Why? A537 through the Peak District, known as the Cat and Fiddle, had severe bends, steep falls from the carriageway and was edged by dry-stone walls or rock face for almost all its
length. Fatal and serious collisions on the route - popular with tourists, goods vehicles and motorcyclists - rose from 15 in the three years to 2005 to 34 between 2006 and 2008. Single carriageway A road. Most crashes happened at weekends during the summer in dry, daylight conditions. 5 Most improved roads 6 ROAD ENVIRONMENT 7
ROAD ENVIRONMENT Roads and deaths 19% of traffic was on motorways, but this accounts for 5% of casualties 38% of deaths occurred on rural A roads with 62% on all rural roads but only 40% of the traffic Nearly 60% of all casualties occur on urban roads 8 ROAD ENVIRONMENT Design of streets and environment Areas of high road user accidents tend to be characterised by: Large open carriage way for vehicles.
Areas of mixed land-use Areas where houses have little or no outside areas for recreation. No segregation of heavy volume traffic from pedestrian and other light traffic. Housing and streets where pedestrian and other travellers safety has not been considered and were often designed pre-motor-vehicle. Hence greater on-road parking and narrow pavements increase road user conflict and increases the potential for accidents (Christie 1995). Crossing of main roads to get to services increases road user danger it has been found that children from families with the lowest quarter of income 9 cross 50% more roads than those in families in the highest income quarter SKILLS Skill Deprivation Self-reported skill Everyone better than the average driver!
Can this be the case? Objective studies suggest 10 Poor hazard prediction Close focus of gaze Inability to multi-task High level of concentration on primary order tasks, leaving little processing for other areas of skill. Steering Gear changing SKILLS
Novice driver eye gaze and fixation 11 SKILLS But does not show why there should be differences between male and female road users. Need to turn to attitudes and other psychosocial variables 12 ATTITUDES Self versus others The public know that driver behaviour is a major
contributory factor in the vast majority of road accidents (Cauzard, 2003) but there is a consistent view that others drive in a more risky manner than individuals themselves do (King and Parker, 2008) Not just driving older children and adolescents think they have good attitude and skills towards road safety but believe that others especially those in their peer group do not (Tolmie. 2006). 13 ATTITUDES Self versus others Individuals do not believe they are dangerous on the roads And
Believe others are a danger on the roads I am not likely to be responsible for an accidents, others are likely to be responsible. Therefore little I can do. Hence, less likely to need to plan to avoid them Campaigns aimed at dangerous driving are for other drivers not themselves. Such campaigns re-emphasise this difference (2CV, 2008 and Flaming Research, 2008) The third-person effect (Davison, 1983). 14 High support for enforcement, engineering solutions and education ATTITUDES Norms Positive attitudes to the speed limit and dangers of
speeding 90% agree important that people drive within the speed limit (British Attitudes Survey, 2005 in DfT, 2008) 39% agree it is dangerous to drive over the speed limit at all 2007) (Angle et al., 76% of drivers completely agree that driving too fast for the conditions is dangerous (Angle et al., 2007) Public support tougher enforcement of speeds especially in residential areas and surrounding schools (Brake, 2004; Higginson, 2005; Holder n-d; Quimby, 2005) 77% support 20mph zones (British Attitude Survey, 2007 in DfT, 2008)
On the whole, the public have good knowledge of the speeding and accident link (Brake, 2004; Fuller, Bates et al., 2008; Higginson, 2005; Holder n-d; RAC, 2007; Quimby, 2005;) 15 But drivers continue to drive over the speed limit A conservative estimate suggests 49% of drivers continue to drive over ATTITUDES Norms Why? Driving over the speed limit is not necessarily speeding Speeding is 1mph over (33%); speeding is 5mph over (33%) (Higginson, 2005) 10mph over is normal view for speeding (Corbett, 2001)
Driving over the speed limit is not necessarily breaking the law 94% of drivers consider themselves law abiding (RAC, 2007) drivers conceptualisation of law abiding does not involve speeding (Moller, 2004). Laws & rules of driving were judged subjectively not simply followed (Christmas, 2007). Social comparison/contagion model Other people are doing it, more often and faster than me Almost all drivers believe other drivers speed (c.90%) (Holder et al., u/p; SARTRE, CAuzard, 2003) More likely to speed if believe others are speeding (Fuller et al., 2008) Other people drive faster than myself (Fuller et al., 2008) A view especially held by younger drivers (Yagil, 1998) and faster drivers (Aberg et al., 1997; Haglund and Aberg, 2005)
OK to drive over the speed limit it isnt speeding, it isnt 16 breaking the law and others are doing it and are doing it more dangerously than myself.

Reduction in accidents Though low numbers before and after Poorer road positioning More difficult to predict driver behaviour Increase in delay to emergency vehicles Increase in pollution Noise Vibration Poorer bus rides 23 ENGINEERING SOLUTIONS infrastructure
Shared space Providing less complex and self-explaining roads, which have clear signage and road markings as well as intuitive infrastructure is likely to benefit all road users, in addition to the older driver (Box et al., 2010; pg. 43) Vs. Creating a more complex to encourage sharing of space and a levelling of priorities amongst different users (Engwicht, 1992; Hamiton-Baillie and Jones, 2005). This should help reduce speeds of drivers who have to informally negotiate the space with other road users and the ambiguity of the road scene. But we dont know the tipping point between the two? what may create complexity and additional attention amongst a younger driver may well be very different to that of an older driver who could find a highly complex environment too difficult to negotiate and actually increase the likelihood of an accident. Further research is needed to examine the interaction between infrastructure design and the affect on ability and skill of older drivers. 24

Probably quite justified first 6 months of driving over represented in accident statistics (esp. youngsters) (DfT, 2008; Emmerson, 2008) Learner drivers have poor conceptualisation of what makes a good driver (Emmerson, 2008) Learning really begins after the test was a view consistently held but reluctant to take formal training (Christmas, 2007) 26 Learning from experience Learning from mistakes Forming habits and learning norms EDUCATION Driving tests, learners and safety Time for radical review of driving learning

Context, theory and interventions Despite widespread deployment, little evidence to suggest attitude and behaviour change (OConnell, 2002; Thomas et al., 2007) Incurable optimism leads people to believe message is not for them (OConnell, 2002) Driver can give drivers an excuse for their behaviour problem is with other drivers (Silcock, et al.,1999) Fear inducing adverts have very little effect on driver attitudes and behaviour (Fylan et al., 2006) Could be methodological problems as much as campaign themselves (Dragutinovic and Twisk, 2006) Lack of theory cited behind the development of the message 30 Popular psychology approach Vs.

ENFORCEMENT SEAT BELT USE Context Compulsory to fit front seat-belts to new cars from 1967. Voluntary use encouraged through clunk-click campaign in 1970s Seat-belt use around 40% Law to wear seat-belts in front of vehicle from 31st January 1983 (3 year trial then permanent from 1986) Seat belt compliance 90% Rear seat-belt use 17% up to 40% in 1991 when made compulsory Up to 85% in 2008 (higher for children) with associated campaigns
32 However, of 1,432 car occupants killed in 2007, 34% had not belted up and of these 370 could have survived if properly 33 34 ENFORCEMENT SEAT SEAT BELT BELT USE USE High compliance Compliance behaviour is clear and unambiguous Legislation was initially heavy but without fines Associated successful
campaigns 35 Behaviour is easy to perform Little associated perceived costs or risk Image is positive ENFORCEMENT DRINK DRIVING Context High support and compliance for drink-driving laws High support for drink-driving laws (Higginson, 2005)
Clamp-down on drink-driving is positively perceived (RAC, 2007) Support for high penalties 72% suggest drink-drivers should get a ban of 5 years (DfT, 2008) 94% support a more severe penalty 85% think limit should be no drinks at all (DfT, 2008) Women and those in lower socio-economic groups are more punitive (DfT,2008). 15-19 year old boys more tolerant than girls about drink-driving (OBrien et al., 2002) but is still unacceptable amongst youngsters (Thomas et al., 2007) Drink-driving known to be major cause of road accidents (Cauzard, 2003; Fuller et al., 2008) 75% thought the public were unable to judge how much they can drink before being over the drink-drive limit, but felt they were able to themselves! Driving on cannabis thought to be more acceptable than drink-driving according to 15-19 year olds (Thomas et al., 2007). Substantial number of drivers who still find it acceptable to have at least 2 36
drinks and drive (Higginson, 2005) ENFORCEMENT DRINK DRINKDRIVING DRIVING Context But high number still drink-drive Serious accidents, (fatalities and serious casualties) involving drink-driving are falling over past 20 years but slight casualties are increasing. 37
Reported casualties: 11,190 (5% of all road accident casualties) Fatalities 380 in 2009 (11% of all road accident fatalities) Serious injured 1,480 Slight casualties 10,130 ENFORCEMENT DRINK DRINKDRIVING DRIVING Legislation 44% of population have driven after drinking some alcohol in previous year 8-9% of population believed they had driven over the limit in last year Most likely to be 17-29 year old males (25% admitted to driving over limit in previous year). Also 17-25 year olds over represented in accident stats relating to alcohol. 38
ENFORCEMENT DRINK DRINKDRIVING DRIVING Legislation Legislation is quite tough Around 500,000 breath tests carried out a year of which around 100,000 are found to be positive. Limit in UK is 80mg alcohol per 100ml of blood (most EU countries are 50mg/100ml and Sweden is 20mg/100ml) Endorsement for drink-driving remains on licence for 11 years Max imprisonment for driving over limit is 6 months and a fine of 5000 and a minimum ban of 12 months of driving Causing death by dangerous driving carries maximum 14 years in prison and a minimum 2 year driving ban (and requirement to take 39extended driving test before being able to drive again)

41 ENFORCEMENT Speed cameras (1) 42 ENFORCEMENT Speed Cameras (2) More on this So they work? Yes Studies have shown that a reduction in the speed limit to 20mph in built-up areas causes a 60 per cent fall in accidents Evidence from Swindon showed a 30 per cent reduction
in the numbers of people killed or injured since cameras were installed At 10 of the sites in Swindon where cameras were introduced, no road accident deaths have been recorded No... Critics say it's not speed that kills but tiredness and careless driving. It's this that should be targeted with safer driving campaigns Speed cameras are being used as an easy way for the authorities to bump up their revenues, antagonising the public 43 Cameras are counter-productive in creating a tendency for drivers to break the speed limit when they are not Road Safety Audit The Road Safety Audit is an evaluation of Highway Improvement Schemes to identify potential road safety problems that may affect any users of the highway and to recommend measures to eliminate
or mitigate these problems. It is now considered by many council officials as an essential, integral part of town planning and many private organisations now consider it at least desirable and often essential. The Auditors need to take all road users into account, particularly vulnerable users such as pedestrians and pedal cyclists. Having identified any potential road safety problems, the Auditors then make recommendations of possible solutions. The client then reviews the findings of the Road Safety Audit, deciding which recommendations to accept, and therefore implement within the scheme design and construction. For those recommendations that are not accepted, good reason should be given. 44 Road safety Audit Road Safety Audits are undertaken at various stages of the highway improvement scheme and comprise:
Stage Stage Stage Stage 1 2 3 4 Completion of preliminary design Completion of detailed design
Completion of construction Monitoring (12 months and 36 months) A stage 1 and 2 Road Safety Audit are quite often combined. Road Safety Audits can be requested for: Major and minor highway improvements Traffic management and calming schemes Pedestrian and cycling schemes New and amended junctions Motorway improvements Road Safety Audits are undertaken by an Audit Team, which must be independent to the Design Team.
The Audit Team comprises of a minimum of two persons with appropriate levels of training, skills and experience in Road Safety Engineering and/or Accident Investigation. The members of the Audit Team may be drawn from within the Design Organisation or from another body. Site visits are a specific requirement of the Audit and both day time and night 45 time visits are usually required in the later Audit stages.
