In the past decade, several researchers have studied the phenomenon of excessive pedestrian-induced lateral vibrations and full-scale measurements of various bridges under crowd loading have been carried out.
The earliest scientific descriptions of excessive pedestrian-induced lateral vibrations are dated back to the 1970s, but it was not until the beginning of the new millennium that bridge engineers fully comprehended the potential negative effect of pedestrian crowds on long-span footbridges.
When these coupled vibration modes are excited by walking pedestrians, excessive lateral vibration can be induced.
Some footbridges are so slender that pedestrian traffic can cause excessive vibrations and serviceability problems.
Although the offense the junkman and the pedestrian take is perhaps excessive, even bullying, these are manly reactions, and not just because they are violent.
"We've set the bar so low that a pedestrian cyclical rebound associated with excessive fiscal and monetary stimulus, arriving just in time for a presidential election, will look spectacular," said Robert Barbera, the chief economist of ITG/Hoenig.
Perhaps the most surprising finding was that excessive weight may prove a boon for pedestrians in a collision.
But, because of the excessive winds, the Golden Gate was closed to pedestrians.
One pedestrian said the $85 fine is excessive.
Poor street condition, heavy traffic and excessive noise correlate with onset of mobility limitation while pedestrian-oriented designs and access to recreational facilities are positively associated with physical activity and self-rated health in older adults.
The modern perception of urban planning is directed towards promoting pedestrian movement and, at the same time, limiting the excessive use of automobiles.
