Abstract
Traffic congestion is a critical problem in fast-urbanizing cities such as Addis Ababa, whose
infrastructure cannot keep up with the increasing demands of traffic. This research takes into
account the degree of congestion on the Asrasament-Compressive Road, which is an outlet
corridor connecting city and suburban areas and experiences more stress in comparison with the
central arterials. The study followed a quantitative methodology. Data collection was based
primarily on an integration of field measurements and observations, manual traffic counts, and
questionnaires. Subsequently, data were examined by descriptive statistics and an approach
adopted from the Texas Transport Institute and World Bank 2013 which computes the economic
cost in Egypt. The study measures congestion levels by travel time method and estimates economic
costs. Peak hours for severe delays are in the morning (8:15–8:30 AM) and afternoon (4:15–4:30
PM) with daily total delays being 67,833 vehicle-minutes (1,130.55 hours) and 508,033 person-
minutes (8,467.21 hours). Direct and indirect annual economic costs are 274.2 million Ethiopian
Birr, dominated by travel time delays. The findings highlight the unique stresses on outlet
corridors, and it is essential to have specific
