This article is about highway and transport engineering, this time we talk about Pedestrian In Traffic Engineering

One of the elements requiring the attention of the traffic engineering is the pedestrian. Particularly in in urban and CBD (central business district) locations, the pedestrian presents an element of sharp conflict with vehicular traffic, resulting in high accident rates and traffic delays. Pedestrian movements and characteristic must be studied for the purpose of providing a design which minimizes pedestrian vehicle conflicts, increases pedestrian safety, and minimizes vehicle delays.

The pedestrian must be accommodated and considered in a variety of situations. At any intersection where pedestrians must cross the street grade, they must be able to do safely and conveniently. Where high volumes of pedestrians exist, these volumes must be adequately provided for by crosswalks. In such cases, it will also be vital to determine peak crossing volumes and peak queues of waiting pedestrians, so that adequate space and crossing time can be provided. In business districts, sidewalks must be wide enough to accommodate prevalent pedestrian volumes. Pedestrian walking speeds also need to be studied, as this will affect the timing of signals at intersection and the amount of space required. Where pedestrians board mass-transit vehicles, it is important that boarding times and other characteristics be studied in order that the bus loading zone, or transit station, may be properly designed as to size and location.

In these cases, the pedestrian and his characteristics are important inputs into traffic engineering decisions, and as such they merit a thorough analysis
