Abstract:
Every day, people are moving to perform their day to day activities and for different
purpose such as for work, school, recreation and others. Currently, pedestrian walkway
capacity is one of the problems in Addis Ababa. The walkway capacity and pedestrian
crossing affects the socio-economic aspects of the city as a whole. Also, there are some
problems occurred due to walkway problems in the city; traffic accident increases and
pedestrian LOS decreases and others. The aim of this research is to estimate the LOS
of walkway rehabilitation projects level of service of Addis Ababa city roads authority
in central Addis Ababa and to establish measurable actions. This paper focused to
assess the pedestrian level of service of the new walkway rehabilitation projects of
Addis Ababa City Roads Authority at selected road sections of central Addis Ababa
city. The study was based on three road sections. The selected sections were from 4
Kilo through Kidste Mariam to 6 Kilo, from Degol Square. to Kidste Mariam, from
Meskel Square to Post Office. In this research, simple random probability sampling
techniques was used. From 18,000 meters, only 3600 meters walkway sections are
selected for assessment. The pedestrian and vehicle traffic volume on the selected
sections and detail geometric data of the walkway are collected to evaluate its level of
service. The traffic data was collected through manual counting. The details of
geometric data and other important parameters of the walkways collected from the
office of AACRA, and field measurement. The analysis performed using HCM 2010
methods, and International Road Assessment Program (iRAP) Software.
Results from HCM 2010 indicated that 80% of the pedestrian sidewalks surveyed are
below LOS C and the results from International Road Assessment Programme (iRAP)
methodology shows that poor performance of the pedestrian walkway and the average
percentage decrease in iRAP score after all countermeasure was taken is 79%. Finally,
most of the pedestrian walkways are in serious problems and need some improvements
such as appoint school zone supervisors at school start and finish times, provide
pedestrian fencing, provide pedestrian refuge at pedestrian crossings, apply speed
management techniques (traffic calming) and reduce the operating vehicle speed.
