Road Safety Flashcards
What are some factors for causing crashes
Road user factors: influence of drugs, poor judgment, inexperience. Vehicle factors: Poor vehicle conditions Road environment factors: Poor geometry/ alignment, hazards, slippery surface
What are the differences between a forgiving and unforgiving road?
forgiving = flat grad, nice smooth surface, comfortable geometry. Unforgiving= Narrow roads, cheap surfacing, tight geometry
What are some human factors
Accounts for 57-65% of crashes Visual sensory system = Not evolutionary equipped for driving at high speeds. Mental workload= stressed minds cause reaction times to decrease. A hysteresis response. Change blindness= What we see may not be there.
what is rasmussens model of driver psycology
Driver skilss = 1) Knowledge 2) Rules 3) skill
What are the specific objectives of the WHO global status report?
Assess the status f road safety of a core set of road safety indicators and a standardized methodology. Indicate gaps in road safety Help countries identify the key priorities for intervention Stimulate road safety activities at a national level
What is the systems approach to road safety
Identify a lead agency in GOVT to guide national road safety effort Assess the problem, policies and institutional settings related to road traffic injury and capacity for road traffic injury prevention Prepare a national road safety strategy and plan of action Allocate financial and human resources to address the problem Implement specific actions to prevent road traffic crashes, minimize injuries and evaluate the impact of these actions; reduce expensiveness and inappropriate speed, reduce drink driving, increased usage of safety measures such as seat belts, support the development of national capacity and international cooperation
What are the 3 approaches to Road safety?
Systems approach = Recognizes human body is vulnerable and humans make mistakes Comprehensive approach = Involves identifying the interactions between the human road user vehicle and the environment Safe road traffic system = compensates and accommodates for human vulnerability and fallibility
What is the safe systems approach?
Human beings make mistakes and crash are inevitable human body has limited ability to withstand crash forces Systems designers and users must all share responsibility for managing crash forces to a level that does not result in a death or serious injury requires a whole approach to implement in NZ
What is the UN decade of action?
Identify 10% of the road network that carries the highest traffic volumes Benchmark road safety performance of the network using assessment ratings
What are the historic laws which has caused reductions in crash?
Seatbelt 1973 breath testing 1987 GFC 2008 Economic recessions population growth
What are some facts about NZ road safety in an international context
Deaths per 100,000: NZ is quite high despite being a small country. Significantly higher than Scandinavian counties, who have adopted a 0 death visions.
What are some post crash analysis methods
Safety= Crash reduction system Behavior = enforcement statistics Distractions = crash types, enforcement
How do high income countries compare to low income countries?
Asia pacific region has the highest road deaths. Due to religious beliefs making people less afraid of death and also because they have large populations Low income countries and middle income countries have more road deaths because they have limited capital so these countries instead focus on more pressing matters other than road infrastructure and safety.
