Increasing the Road Capacity Not Always Improves the Travel Time: A Before and After Study in Tirana
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 1
Abstract
The rapid growth of the car ownership last two decades in Albania has increased the need for higher transportation capacity. One of the most affected cities in Albania is Tirana where the capacity has not met the demand. Inevitably, the center of Tirana (Skanderbeg Square) plays a crucial part in Tirana Transp ortation System. After a closure of about 2 years, being under reconstruction planned to be car-free area, Skanderbeg Square opened to traffic in 2011 by motorizing it again. This study analyses performance parameters such as: Travel Time, Waiting Time, and Passenger Movements for bus and passenger cars passing through the Skanderbeg Square before and after it was opened to traffic. Kinostudio-Kombinat bus line has been selected as the only line passing through the center of Tirana. Changing the land use from car-free to motorized one has created a valuable possibility to compare the traditional approach; which focuses only on cost to the sustainable one; which includes the environment and social aspects, too in the evaluation. Wider roads, shorter travel times and higher speed travel at the center (CBD) have made vehicle usage more attractive. At the same time, bus travel times have been improved at the center of Tirana. However, the total travel times were not only enhanced, but at some locations (especially near the CBD) where deteriorated. This study showed that traffic congestion problems are not solved but are shifted to other parts of Tirana Transportation System. In addition, public transportation revealed to be overcrowded, forcing passengers to use other modes like passenger car. Last but not least, other modes like bike or motorcycle riding should be encouraged as alternative to the passenger car.
