Impact Of Vehicular Traffic Congestion On Worker Productive Time: The Case Of Autobus Tera, Addis Ababa

Abstract

Urban transportation is a vital aspect of human life processes, as it aims to fulfill the need for mobility and accessibility to various activities, but this activity affected by traffic congestion. Suffer from congestion, leading to high operational costs, loss of time, high delay and high travel time. This study focuses on assessing the issue of traffic congestion in Autobus Tera, Addis Ababa and how it affects workers productive time. The purposive sampling technique was used when selecting workers who use public transport, like public bus, taxi and ride to arrive and departure from Autobus Tera. The data was collected using questionnaire and GPS instrument. Travel time index (TTI) is the ratio of the average travel time during peak period to the travel time during off peak period. The maximum Travel time index was 7.08. Workers spent about 7.08 times of the average commuting time travel to work place and back to home. About 3 hours and 13 minuities were lost due to traffic jam per day ( 21 hours and 9 minuities were lost due traffic jam per week). It was further established that in 8 working days, almost 3 working days were lost due to traffic congestion. The study results prove that the Travel time index (TTI) value in all selected routes greater than 2 this indicates inefficient transport system and the result shows that when people live closer to their workplace, they spend less time commuting. Urban planning decisions that lead to lower travel time index between home and workplace can improve communities effective time. Proximity between work place area and residential area during planning of the city is highly recommended for effectivity of workers.
