    This study appraised the state of urban transport in a Nigerian traditional city. It examined commuters’ socio-economic and transit characterization, assessed the quality of transport infrastructural facilities and services, and identified the challenges of urban transport services in Ibadan city, Nigeria. 163 copies of questionnaires were systematic randomly administered on commuters along six (6) selected traffic-corridors in Ibadan. Both descriptive and inferential (Binary Logistics Regression) statistics were used for data analysis. Major findings revealed majority (about 40%) of commuters were civil servants and earn above 90,000 naira as monthly income. Mean Weighted Value results show that taxi (3.913) and motorcycle (3.756) are dominant and most patronized means. Similarly, the availability (4.075), safety (4.000) and affordability (3.625) were most-weighted factors influencing commuting modal choice, while a trip to work (3.718) and market (3.200) are most generated trips in Ibadan. Meanwhile, most of the assessed infrastructural facilities were of poor quality, while peak/off-peak transit issues (4.050) and vehicular mechanical failure (3.487) were major challenges affecting urban commuting. Binary logistics regression results show that the condition of urban transport infrastructural facilities significantly influence overall satisfaction with urban commuting (p < 0.000). Cox & Snell's R-Square (36%) and Nagelkerke’s R (70%) show that the model is relevant in predicting the relationship between dependent and independent variables. The study concluded that there is a need to improve urban transport system towards ensuring commuters satisfaction and urban development. Hence, recommended among others, integrated transport system with smart devices and improved conventional public transport scheme in Ibadan.

    The Use of Matlab in Creating M/M/n/∞ Queuing Theory Model
    (University of Zilina, 2020) Mojský, Viliam; Achimský, Karol
    In our research we dealt with the creation of an algorithm designed to simulate M / M / n queuing systems with endless queues. The algorithm was created in Matlab. When creating the algorithm, we proceeded according to scientific literature, according to which we transformed the formulas into the Matlab algorithm. This process also included the optimization and creation of new outputs based on the analysis of the generated data. The research output is a Matlab algorithm suitable for creating simulations of M / M / n / ∞ systems.

    An Assessment of Solid Waste Transportation in Ado-Odo/Ota Local Government Area, Ogun State, Nigeria
    (University of Zilina, 2020) Ogunbiyi, Margaret Emem; Onifade, Morakinyo Kehinde; Afolabi, Oluwaseyi Joseph; Oroye, Olufemi Adebayo
    This paper examines solid waste transportation in Ado-Odo/Ota Local Government Area of Ogun State. Adequate transportation of solid waste is one of the major challenges of waste managers in Nigeria because of inherent factors ranging from dearth of transport infrastructure to poor attitude of residents. Data were collected through the aid of questionnaires, personal observations, visitations to some villages and towns as well as dumpsites. The questionnaires were divided into two parts: household respondents and solid waste management staff. The data obtained were analyzed using Descriptive Statistics, Factor Analysis and Item Analysis. From the analysis of the data obtained from household and waste management respondents the mean and standard deviation reflect high degree of correlation and concurrence. From the principal component analysis of both the household respondents and waste management staff, there are two principal factors respectively that should be given higher consideration in solid waste management in Ado-Odo/Ota Local Government Area. These factors include waste collection and disposal method, frequency of collection and reliability of waste vehicles. Based on these findings, the study concluded that attitudinal change on the part of the household, government intervention on road maintenances, and adequate maintenance of PSP vehicles will go a long way in reducing the heaps of refuse and indiscriminate dumping of solid wastes in the entire vicinity of Ado-Odo/Ota Local Government Area in Ogun State, Nigeria.
