Abstract
As of now in Addis Ababa there are so numerous issues which are basically concerned with
deficiency of stopping space such as congestion of streets due to imbalance between on-street
parking capacity and demand of parking space by vehicle and Regarding this problem Addis
Ababa city traffic management agency has been implementing different types of parking
facilities one of which is marking of Box on Street parking areas on the outer lane of the existing
roads. However; the effects of these areas on existing traffic and efficiencies of these parking
facilities on service condition are not assessed adequately. Therefore this study asses
accordingly the effects and efficiencies of legal on street parking in Addis Ababa a case study on
Nifas silk lafto Sub-City From Bisrate gebriel square to Karl square. methods used for data
collection were field survey to conduct a comprehensive parking occupancy survey ultimately to
find the characteristics and efficiency of the parking space, to find vehicle maneuvering time
which are used to estimate the reduction of the adjacent lane capacity because of disruptions of
traffic flow while maneuvering of vehicles from parking lane. In the instance of secondary data
collection, relevant information was retrieved from relevant materials, such as published
literature and internet-based sources.
The results of the study indicate that on-street parking facilities in Bisrate Gebriel square to Karl
square road segment are inadequate mainly on mid-day period leading to illegal parking.
Another result of the study shows that reduction in lane width of traffic lanes and vehicle
maneuvering of parking vehicles on adjacent lane impacts road capacity. The average speed of
vehicles by 6.25 %.Which was found to reduce a speed of 0.0382 km/hr. for each percentage
increment of parking occupancy when on-street parking is considered removed from the kerb
side of the road this reduction on road capacity due to both allocations of traffic lanes for onstreet
parking and Disruption of Traffic flow of adjacent lane.
