Road traffic behavior

The Social Attitudes to Road Traffic Risk in Emope (SARTRE) project started in 1991. It consists of a European wide survey about knowledge of road traffic laws and road traffic risks, attitudes regarding road safety issues, repotted road traffic behaviors, transport habits and needs in several European countries. Variorrs topics related to road safety are the focus of the project such as alcohol, drags or phone use while driving, speeding, use of advanced driver assistance systems and the transport infrastructure and envirorunent. After the first edition of SARTRE, a follow-up was performed in 1996 (SARTRE2) and 2002 (SARTRE 3). For this fourth edition of the... 

Employers should make road traffic safety a priority, enforcing policies that require use of safety belts and prohibit unsafe behaviors such as impaired driving and use of cell phones and other mobile devices that might distract the driver while the vehicle is in motion, the report concluded. 

In connection with road traffic, with its special condition of self-determination of the rate of work, studies by Taylor [6-40] and Wilde [6-41] have indicated that there is an adequate awareness of the risk content in particular situations. Both authors carried out field experiments which showed that drivers regulate their behavior within the MME-system so that the risk they experience fluctuates only between narrow limits. Thus Taylor reported that drivers tend to increase the speed of the vehicle in situations in which low risk is perceived, and to reduce speed if the perceived risk increases again. The perceived risk was determined in these experiments using the psycho-physiological measure of the galvanic skin response. In a similar experiment Galton and Wilde [6-42] showed that the subjective risk was determined on the basis of a verbally formulated risk scale. The test route consisted of 11 sections with heterogeneous traffic...

Although this table was developed for a different industrial sector the behavior types match well with the situations of a driver in road traffic, and the values can therefore be used for assessing the significance of human error in vehicle based systems. 

In the remainder of the book I will explore the reasons why highway safety is improving - and the reasons why it isn t, especially from the perspective of the road user behavior. Because the road user - driver, cyclist, or pedestrian - has been historically viewed as the only decision maker in the driver-vehicle-highway system, his or her role is critical. But the driver does not behave in a vacuum. The roadway environment and the vehicle characteristics are crucial components in the highway traffic system, as are other vehicles and road users, the legal and...

As the information on how road nsers perceive mles, measures and behavior in traffic can give additional insight in the pubhc snpport for certain measures taken or to be taken and the self-reported behavior also gives some additional insight in road user behavior, related data on road nser attitnde and behavior were selected and gathered. The SARTRE studies provided an appropriate source for this information. The studies span a number of years (1996, 1999, 2003 and 2011) the data are harmonized between European countries and are updated. From the SARTRE studies, the following issues were selected because they are relevant for road safety driver behavior (self-reported) and attitudes towards risk taking. 

Enforcement of traffic rules is an indispensable ally of other safety measures [ELV 04b] to promote homogeneous and safe traffic behavior between all road users. PTW operators, as other operators of motorized vehicles, must comply with traffic rales and typical enforcement activities, to control speeding, drinking and driving, non-respect of traffic rules, etc. 

Among others factors, the potential safety of a section of road is affected by its geometrical characteristics, features such as crossings and intersections, the lighting and signage, and the traffic behavior, as well as various dynamic factors relating to weather conditions, e.g. areas prone to ice. Examples of features, which can be responsible for safety risks in rural and urban road environments, are listed below ...

X Assessing applicants — Seventy percent of all companies (90 percent of large carriers) use safety-related criteria to evaluate driver applicants. Ninety percent or more of carriers use drug testing, past traffic records, on-road tests for evaluating driver behavior, and license qualification checks as effective means of assessing the safety risk of driver applicants. 

A generic term that mainly encompasses vehicle safety features, driver and pedestrian education and behavior, motor vehicle laws, and factors related to the design of roads and highways (Figure T.l).

The ABM approach is employed in the modeling of car traffic because it is able to capture individual drivers preferences (Galus et al., 2012). In particular for electric car mobility, ABM takes advantage of high resolution road network maps and allows for an accurate mapping between the transportation network and the electricity infrastructure. However, in order to evaluate interdependencies between road and electricity network, detailed data on the electric equipment, drivers behavior, and power demand are needed. 

The last part. Crash Causation and Countermeasures, focuses on what we have learned over the past one hundred years - and especially over the past few decades - about the causes of traffic accidents, their relative frequencies, and the means that have proven successfiil in combating accidents. The crash causation chapter also has a methodology component, because often the relative frequency of various causes of traffic accidents is methodology-bound meaning that different methods of analyses yield different conclusions. The countermeasures chapter is divided into first domains in which countermeasures can and have been applied organizational actions (such as "Vision Zero" mentioned above), behavioral changes in drivers and other road users, environmental treatments of the roadway and its furniture, and vehicular changes in both crash prevention and injury reduction. 

How we perform the tasks at each level - what biases, constraints, desires, limits, and skills govern our behavior is the subject matter of the theories and models researchers have proposed to explain on-the-road behavior. Note that our behavior does not occur in a vacuum, but has environmental inputs . These include not only the visible and immediate inputs from the roadway, the traffic, the weather, and the lighting conditions, but also the less tangible environment consisting of traffic laws, norms of behavior, and culture that govern the way we drive. For example, it is the latter that are responsible for stereotypes of New York drivers , Italian drivers , Israeli drivers , and English drivers . 

A written test and a driving test administered by the state. The written test assesses knowledge of rules of the road and various aspects of prudent driver behavior, while the driving test assesses the candidate s ability to handle a vehicle (but not necessarily in traffic).
