- ItemAssessment of Flow Rate of Motorcycle in Ibrahim Taiwo Road, Ilorin Metropolitan City-Northern, Nigeria(Journal of Architecture and Civil Engineering, 2021) Biliyamin A. Ibitoye, Mariam Funmilayo Daudu, Nurudeen A. Ibrahim, Nurudeen A. Adeyemoh, and Mukaila B. KazeemSharing of lanes by motorcyclists can cause injuries to their body because of the exposure of the part of the body due to the design of motorcycle. Due to lane sharing by motorcyclists’ fatal accident may occurred which can lead to death of the motorcyclists and lane splitting leads to confusion at intersections. Road accident in Nigeria is attributed to many reckless motorcyclists and absence on motorcycle lane forming part of the road. Motorcycle lane design and construction are important to reduce road accident claiming lives and causing causalities. This justifies the study on motorcycle lane design considering geometric features, traffic data and road users as elements of the design. Raw data were collected at Ibrahim Taiwo road Ilorin from four different sections, A,B,C and D using video recording from Monday to Sunday at the peak hours of 7am-9am in the morning and 2pm-4pm in the afternoon.
- ItemThe Effects of Styrene-Butadiene (SBR), Polyethylene Bag (PEB) on the Properties of Bitumen(Global Scientific Journals, 2020) Ige J. A., Ibitoye B. A. and Adeyemoh N. A.This study investigates the use of Styrene-butadiene (SBR) and Polyethylene Bags (PEB) as modifiers on properties of bitumen. Bitumen modifier (SBR, PEB and SBR/PEB) at 0, 3, 6, 9, 12 and 15% by weight of 500g hot bitumen were used. The bitumen and percentages of SBR, PEB, and SBR/PEB were heated until the PEB, SBR, and SBR/PEB added was melted, thereby stirred thoroughly with each other in each container of the specimen. The modified bitumen (i.e. bitumen with the additives at 3, 6, 9, 12 and 15%) and unmodified bitumen (control bitumen) were allowed to cool to a temperature of 85oC. The modified and unmodified bitumen were subjected to penetration, ductility, softening point of bitumen, and flash and fire point of bitumen tests. The results obtained in each test shows that using SBR/PEB as modifier on the properties of bitumen would not only increase the lifespan of the road pavement but also serves as the means of managing the waste menace.Utilization of these waste (SBR and PEB) in bitumen proved that it would enhance the properties of the bituminous mix in addition to solve disposal problem.
- ItemComprehension Analysis of Traffic Signs by Drivers on Urban Roads in Ilorin, Kwara State(Journal of Engineering Research and Reports, 2022) Sikirat Damilola Mustapha and B. A. IbitoyeTraffic signs are the oldest and most commonly used Traffic Control Device (TCD). These signs convey messages in words or symbols and erected to regulate, warn, or guide the road users (motorists, and pedestrians). This study investigated the level of compliance of traffic control devices among drivers with different sociodemographic characteristics in Ilorin. A descriptive research design of survey type was used in the conduct of the study. The population for this study covers commercial and private drivers in Ilorin. The research instrument used for the study is a well-structured questionnaire. The data gathered were analysed using frequency counts and percentage for the demographic data, and factors that affect the non-understanding of drivers to traffic control devices. Statistical analysis was done with SPSS. For chi- square, only the years of driving experience was found statistically significant with a p-value of 0.006 and for Analysis of Variance (ANOVA) both educational experience and years of driving experience were found to be statistically significant with p-value of 0.001 and 0.000. It was deduced that major factors affecting the non-understanding of traffic control devices by drivers in Ilorin were lack of previous knowledge of the signs, lack of adequate enforcement and non-availability of control devices on most roads in Ilorin.
- ItemUnderstanding of Traffic Signs by Drivers on Urban Roads – A Case Study of Ilorin, Kwara State(Journal of Engineering Research and Reports, 2022) Sikirat Damilola Mustapha and B. A. IbitoyeThe effectiveness of traffic signs, which are used often to promote safe driving and are designed to convey critical information quickly, is contingent on drivers' ability to understand them. Therefore, researchers in Ilorin set out to determine how well-understood and compliant traffic control devices were among drivers representing a range of demographics. The study was conducted using a descriptive survey research approach. The population for this study covers commercial and private drivers in Ilorin. The three local government areas in Ilorin were selected Ilorin South, East and West. A multi-stage sampling technique was used to select three hundred and eighty-four (384) drivers from the population for the study. The research instrument used for the study is a wellstructured questionnaire. Statistics including frequency counts and percentages were used to examine the demographic information, the total proportion of drivers who properly recognized the traffic control device, and the variables that contribute to drivers' inability to comprehend traffic control devices. The average comprehension percentage of warning signs, regulatory signs, information sign, driver’s knowledge of road marking 56.1%, 60.3%, 64.6% and 59% respectively. The study's findings revealed that 60% of drivers in Ilorin generally comprehended traffic control devices.
- ItemEvaluation of Traffic Congestion in an Urban Roads: A Review(ABUAD Journal of Engineering and Applied Sciences (AJEAS), 2024) Sulaiman Olayinka SUBAIR, Biliyamin Adeoye IBITOYE and Abdulrauf Toyin KURANGAUrban traffic congestion significantly impacts economic productivity, environmental health, and residents' quality of life. This study provides a comprehensive evaluation of traffic congestion in urban areas, focusing on recent innovations in traffic management, urban planning, public transportation, and technological advancements. Intelligent Transportation Systems (ITS), incorporating real-time data and adaptive signal controls, have proven effective in reducing delays and improving traffic flow. The study underscores the importance of mixed-use urban planning in minimizing travel distances and traffic volumes. Expanding public transportation networks is highlighted as a critical strategy for alleviating congestion, with evidence indicating that cities with extensive transit systems experience lower congestion levels. Additionally, the environmental and health implications of traffic congestion are considered, linking high congestion levels to increased pollution and negative health outcomes. . Road construction as a policy intervention to reduce congestion is debated, with the understanding that road widening may sometimes increase traffic. Evaluating the technologies contributing to congestion is crucial for devising effective solutions. Urban transport is central to economic activity and the well-being of urban residents. The rising population and car ownership rates, coupled with unchanged natural land areas, exacerbate traffic issues, leading to accidents and increased carbon dioxide emissions. The article explores the complexities of urban road traffic, addressing transport infrastructure, organization, and the high share of car traffic. It discusses theoretical and practical aspects of traffic flow and design, as well as the role of driver behavior in traffic jams.
