    An Investigation on Safety, Comfort and Convenience of Pedestrian in Addis Ababa: A Case of Arterial Street’s Sidewalks
    (Addis Ababa university, 2020-06) Abebe, Nardos; G. Woldeamanuel, Mintesnot (professor)
    All major cities including Addis Ababa experience heavy pedestrian flows. Because of the shortage of satisfactory sidewalks, pedestrian roadways are often difficult to walk on. Since pedestrians are more vulnerable than other mode users, the primary objective of this research is to develop an understanding of the root cause to safety, comfort and convenience problems while using sidewalks, using pedestrian level of service and user rating methodology. Sidewalks play an essential role in transportation. Sidewalks deliver an isolated safe route for people to walk along a separated trail from motorized traffic movement. Instead of taking traffic flow operation as the assessing standard for pedestrian comfort convenience and safety, this research has studied the methods of assessing pedestrian level of service by analyzing both the pedestrian’s subjective perceptions and objective quality of the service. This study has used two types of PLOS methods, the Australian method and the Highway Capacity Manual integrating with both objective measurement and subjective assessment. The study also uses sidewalks with street vendor activities on them. The presence of street vendors along the sidewalk is neutrally considered, neither unimportant nor important. Their existence is noted because of the negative impact they may have on the available space for walking. The subjective assessment is mainly based on the user’s rating of pedestrian amenities using 821 individuals in 21 selected sidewalks in order to identify the perception of users for that designated segment. The objective measurement was taken in 21 selected sidewalk parts that are located throughout the city of Addis Ababa in order to identify the service level by fulfilling all the affecting factors required by the two PLOS methods. The results of the study indicate that both the PLOS and the perception assessment describes the studied sidewalks similarly with problem caused by vendor activities, pedestrian volume, and the number of pedestrian who interact with street vendors along with the shortcoming of the street network and sidewalk infrastructure in the form of physical and user characteristics.
