BEHAVIOR OF PEDESTRIANS AT UNSIGNALIZED CROSSWALKS WHEN ALONE VERSUS WHEN IN A GROUP: AN OBSERVATION STUDY
IE 6910 Human Factors in Transportation Systems
Dhiraj Kumar Reddy Bokka
Pedestrian safety is a major cause for concern throughout the world as they represent the largest group of road-users and are more susceptible to physical injuries when involved in a crash. In the United States, pedestrian fatality has increased over the years, in 2012, 4743 pedestrians were killed in traffic crashes,which was a 6% increase as compared to 2011 (Traffic Safety Facts 2014). There have been substantial amount of research conducted on pedestrian behavior. One such study illustrates that the primary reason for vehicle and pedestrian crashes were attributed to risky behavior and incorrect decision making by the pedestrians while they crossed the streets (Zhou et al, 2009). Risky behavior could involve not abiding by the general safety precautions while crossing the streets, for example use of cellular phones, not being attentive to oncoming traffic, jaywalking or crossing the street when the red light is on.
This study aims at quantifying the pedestrian behavior at unsignalized crosswalks on Clemson University campus; where cars, mopeds, walking and using the transit are major transportation options. There is a continuous interaction between the pedestrians and the vehicles and thus, there is an increasing need to improve pedestrian safety as their well-being is important to maintain the overall safety culture of a university.
In a university setting, students are very often seen commuting in groups. Conformity tendency is a personality attribute which is a...

...rians observed would be greater than 30, the data will have a normal distribution. We are interested in the mean number of people looking both sides (i.e. being attentive) while crossing in groups and the mean number of people crossing attentively when crossing alone and comparing both the means by making use of statistical tools like SAS tool to draw our observations. If the mean number of people looking both sides in case of crossing alone is higher, then we can say we have sufficient evidence to draw conclusion for our hypothesis. Combined Box and Whisker plots would also be used to determine the mean number of people who are attentive on road depending on the group sizes and simultaneously compare mean number of attentive pedestrians for several group sizes. This will also guide our study on the maximum number of people who can cross the road safely as a group.

- Summary Robert Putnam's basic thesis is that there is a decline in civic engagement in urban cities. He goes on to explore different probable factors that are causing the decline in civic engagement. First off, he dichotomizes civic engagement into two categories: machers and schmoozers. Machers and schmoozers are people who engage in formal kinds of civic engagement (following politics) and informal kinds of civic engagement (hanging out with friends) respectively. Civic engagement, overall, is on the decline according to Putnam (informal activities in particular, however, are ones that Americans, on average engage in more often)....

- It is fairly simple for people to be regarded as a person who is suspicious, or subversive. Another thing which is very easily done to people is to dismiss them.

As the man was taking a walk, it seemed like a very cold place from the start of the story. As he gets stopped by the police car it begins to talk to him.... [tags: Ray Bradbury, The Pedestrian]

- Mankind has made great progression with inventions such as the television. However, as people dedicate less time to study or participate in sport, and dedicate more time to tune into their television, one might wonder if this is growth or decay. In "The Pedestrian", Ray Bradbury has decided to make a statement on the possible outcome of these advances. Through clever characterisation, themes and imagery, he shows that if society advances too greatly, then mankind may as well terminate itself.... [tags: Ray Bradbury, The Pedestrian]

The world in the year 2053 is populated by people who are more dead than alive. Their technology has made them very lazy. Walking has become obsolete, as the title of the story indicates....
