Technology issues and driving education

With more and more drivers competing for limited roadway space, traffic engineers
and safety experts are looking to new technologies to counter problems of congestion,
aggressive driving, and crashes.
The new technologies-such as automated toll roads, road pricing, intelligent
vehicle systems, smart highways, and electronic displays of information-may
offer benefits, but they also create issues and negative effects in relation
to freedom of travel, the role of the automobile in the transportation system,
driver responsibility, the environment, and even safety.
As leading risk psychology expert Gerald Wilde brilliantly demonstrates in
his book Target Risk , efforts to increase
safety through technology often have limited, or even opposite effects. People
seem to have a level of risk they accept in their lives, and technologies aimed
at reducing risk tend to lead to changes in behavior, Wilde argues. Unless
motivated otherwise, he says, they will tend to simply use the technologies
to get more benefits from the system, while maintaining their risk at the same
level. A prime example of this is studies showing that drivers of cars with
Antilock Braking Systems (a great improvement in braking technology) tend to
have more crashes rather than less. They tend to drive faster and more vigorously
than drivers without the systems.
Professor Wilde proposes that improving risk perception and reducing risk
acceptance through training, education, and motivation can be effective strategies
for countering these tendencies.
Even technologies that provide useful information to the driver can have their
problems. One problem is the danger of distraction. Giving a driver information
about congestion ahead, or a turn required to reach a destination, might be
too much if the driver is already overloaded due to things happening around
the car. Another problem is deciding the form in which information should be
provided. Individuals relate to information differently. Some prefer to hear
it, others to see it.
Cognitive Mapping is a branch of science that studies how people perceive
the world around them and how they best relate to information about it. It
covers such issues as the design of maps, signposting, human-machine interfaces,
and control systems.
Gary Burnett, a project officer with the HUSAT Research Institute at Loughborough
University in the U.K. is working on the design of human-machine interfaces
for the cars of the future. He's concerned that giving drivers guidance information
in terms of distances ("turn left after 300 metres") is not very effective
since many drivers appear to have a poor sense of distance. It can lead to "significant
visual demand" on the part of the driver, he says, as they become overly concerned
with in-vehicle visual displays. Junction layout information such as landmark
descriptions might be better, he suggests.
However, descriptive information can be a problem too. Landmarks change, and
in today's visually messy driving environment it's not always easy to recognize
intersections or distinguish them from other roadway features (such as entrances
to shopping plazas). As well, individual drivers may be visually tuned to different
kinds of cues and it could be difficult to design an information system to
suit most drivers. Consistency of roadway design could help here, and that's
something that traffic engineers are working on, says Richard Pain, a safety
coordinator with the U.S. Transportation Research Board.
Roadway design will increasingly conform to standards that drivers expect,
says Dr. Pain, and standardized visual cues will help drivers recognize roadway
features such as intersections and types of highways. The Netherlands, he points
out, have plans to adopt their entire road system to this concept within 20
years. "They've selected three primary categories of highways on which design
will match driver expectancy." The U.S. also has a federal highway design consistency
project under way, he says.
Driver educators may be able to play a significant role in matching driver
abilities to new technologies aimed at assisting them. In addition to informing
drivers about the technologies, and the issues surrounding them, educators
may be able to help drivers adapt. For example, they might be taught to perceive
distances, or roadway features, more accurately.
Developmental psychologist Catherine Sullivan sees a possible role for education
and training in helping drivers match with new technologies. However, she points
out, "individual differences are here to stay. It may not be possible to teach
someone who has problems with spatial information to estimate distances accurately."
"Any new device requires a certain degree of learning, and a happy medium
could be reached by finding out what system is easiest to learn," she says.
However, Dr. Sullivan adds "machines and systems should be designed to fit
the needs of the learner rather than the other way around."

Ramses,
What a truly beautiful seticleon of British cars thanks for uploading.I'm English so remember some of these models commonly on the road as a youngster. On our walk to school my brother and I always used to pass and admire a yellow Triumph Dolomite Sprint parked in a drive not far from our house.The Jag E-Types you have are particularly stunning. Bravo!
