A preliminary evaluation of the impact of covid-19 on public transportation in Ibadan metropolis: a case study of Ibadan North local government
(Nigerian Society of Engineers, 2020-09) Okunlola, O.; Akintayo, F.O.
A number of measures have been put in place by different governments to combat the spread of Covid-19 virus. The virus has affected all forms of transportation. This paper is a preliminary study to evaluate the impact of Oyo State government lockdown measures on public transportation in Ibadan North Local Government Area between March and June 2020. Seven factors affecting public transportation as identified from literature include: availability of service, cost of service, comfortability safety /social distancing, parking difficulties and rate of accidents. Structured questionnaires were administered to purposively selected road users. The level of importance of each factor was determined and ranked by Relative Importance Index (RII). The study shows that there was a significant reduction in travel demand which in turn caused a significant increase in cost of transportation and waiting time for commuters.
Analysis and Design of Intersection for Improved Traffic flow at Awolowo Junction, Bodija Ibadan, Nigeria
(Department of Civil Engineering, University of Ibadan, Ibadan, Nigeria, 2019-12) Adigun, T.; Okunlola, O.; Akintayo, F. O.
Traffic Congestion is inevitable for residents of economically dynamic cites therefore city authorities have to devise means of managing congestion to ease commuters of constrains imposed upon them by traffic congestion. The need for improvement of traffic flow at Awolowo Junction Bodija Ibadan is germane due to traffic congestion at this intersection. The aim of this study is to improve traffic flow at Awolowo Junction Bodija Ibadan. Traffic survey was carried out at the intersection, the peak hour factor and the design hourly volume were determined then the saturation flow rate and the cycle length (using the concept of volume-to-capacity ratio) were determined following the steps outlined in the Highway Capacity Manual, thereafter the yellow interval and the green times were computed. The peak hour was between 4:00 pm - 5:00 pm with a flow of 2989 vehicles per hour and a factor of 0.94 with design hourly volume of 539, 1464 and 1177 vehicles per hour for North, West and East approach respectively. The data collected was checked against the traffic signal warrants of the Manual on Uniform Traffic Control Device and yielded positive result with warrant 3. The saturation flow rate was computed to be 2618, 4320 and 3913 vehicles per hour for the North, West and East approach respectively with a flow ratio of 0.21, 0.34 and 0.3 for North, West and East Approach respectively. A pre-timed traffic control signal was designed to improve traffic flow at Awolowo Intersection of UI/secretariat Road.
Gender in Civil Engineering Education: A Case Study of the University of Ibadan, Nigeria and Institut d’Enseignement Superieur de Ruhengeri,Rwanda
(Department of Civil Engineering,University of Ibadan, Nigeria, 2022) Akintayo, F. O.; Nyirajana, J.; Okunlola, O.
Engineering and technology are basic in any country’s development. Addressing the gender gap in civil engineering education will help to narrow the gender pay gap, enhance women’s economic security and ensure a diverse and talented STEM workforce. This paper focuses on gender disparity in civil engineering education at Institut d’Enseignement Superieur de Ruhengeri (INES), Rwanda, and the University of Ibadan (UI), Nigeria. Data were sourced from the graduating records of the Departments of Civil Engineering, INES Ruhengeri, Rwanda, and the University of Ibadan, Nigeria, covering a period of 5 years (2016 - 2021). Data were analyzed using excel tools. The Department of Civil Engineering, University of Ibadan, recorded a slight increase in the number of female graduating students from 5 in the 2015/16 session to 6 in the 2020/21 session, representing a 20% increment and a slight reduction in the number of male graduating students in the department from 37 in the 2016/17 session to 28 in the 2020/21 session representing a 32% reduction. At INES, Ruhengeri, the number of male graduating students in the Department of Civil Engineering increased from 46 in the 2016/17 session to 145 in 2020/21, showing a 215% increment, and the number of female students increased from 18 in 2016/17 to 23 in 2020/21 showing an increment of 28%. The overall percentage of females in civil engineering education is below 20% compared to over 80% of males in the two institutions. Although the number of male graduating students decreases as the year progresses, the increase in female graduating students is not significant. Hence the gender gap seems to remain with year progression. The study proposes an improvement in motivating female students by providing scholarships, including pedagogical motivation in science courses
