Title: A COMPARATIVE ANALYSIS OF GRILLAGE METHOD AND BEAM LINE ANALYSIS OF A REINFORCED CONCRETE WAFFLE BRIDGE DECK Authors: Adamu, H. N.; Abbas, B. A.; Abubakar, M.; Yusuf, A.; Kolo, D. N.; Shehu, M. Abstract: The analysis of a reinforced concrete waffle bridge deck using Chanchaga Bridge as a case study was carried out with the aid of computer programme written in MATLAB. The bridge deck which is a beam bridge was idealized to be a waffle slab. A mathematical model of the bridge was developed using the method of grillages because very complex shapes of problem domain with prescribed conditions can be handled easily using the method. The bridge deck was modelled as interconnection of grid elements. The analysis was carried out using direct stiffness matrix method. The nodal displacements and the resulting static internal forces; shear forces, bending moments and twisting moments of each grid element were determined using the matrix. The results obtained using the method of grillages were then compared with beam line analysis and the former method gave a 10% decrease in forces which will result in the reduction of overall design and materials by 10%.

Title: Drivers’ Seatbelt Usage, In Minna, Northern Nigeria Authors: Kolo, S. S.; Adeleke, O. O.; Yusuf, I. T.; Abdulrahman, H. S.; Shehu, M. Abstract: Five settlements in Minna, Niger State capital were examined to determine drivers` attitudes and behaviours regarding usage of seatbelts. Multiple data Collection methods consisting of semi-structured interviews to create questionnaire for an in-person survey for 100 drivers each, for five different locations that was used. The questions explored why Minna drivers used or do not use seatbelts and what they think would be the best interventions to increase the rate of seatbelt usage in Minna by drivers. The outcome of all the aforementioned were translated into charts and following outcome was obtained. The composition of gender, for the respondent are 87% male and 13% female, showing that, out of this number 33% are married while 64% are unmarried and 3% are divorced. The finding also showed that the most prevalent age of driver is between age 36 to age 45 and it is said to be the productive age. It was also discovered that majority of the driver interviewed are Nigerlite constituting 64% of those interviewed. It was also noted that, a driver is 87% safer when seat belt is used as compared to not using seatbelt of 37% safe when accident or crash happen. It was therefore advised that sustained radio and television advertisement be done to encourage the use of seatbelt in Northern Nigeria.

Title: Enviromental effects of road construction waste in NIgeria Authors: Kolo, S. S.; Abdulrahman, S. H.; Kolo, D. N.; Shehu, Mohammed; Adamu, H. N.; Eze, F. E Abstract: This research work investigates the various waste streams generated during road construction and their effect on environment. The method employed in this research work is categorized into waste type generated on construction site using reconnaissance surveys, data collection and data analysis methods. Four construction project sites in Minna, Nigeria, were used with the aim that these sites will provide a platform to acquire valuable data. It was discovered that mortar or concrete waste and wood waste has the highest percentage of 22% to 39% and asphalt has about 4 % waste and this was largest percentage of waste generated and this was mainly due to the human error, the use of inadequately trained and unskilled labour. The study however made case for adequate attention and concentration towards improving effective waste management by implementing proper waste management and disposal systems and encouraging the use of recycled materials in road construction. This will greatly reduce the cost of construction, increase efficiency, reduce work time and replenish the earths rapidly depleting natural resources used in construction like wood and bitumen.

Title: Development of optimal and cost-effective bus scheduling using genetics algorithm Authors: Shehu, M.; Kolo, S. S.; Jimoh, O. D.; Adeleke, O. Y; Taiwo, O. A.; Fetuga, I. A. Abstract: Most higher institutions in Nigeria operates intra and inter campus transportation, but lack proper planning on movement schedule which contributes significantly to poor academic performance of students as it causes great fatigue due to long queue at the parks and consequently, resulting to losses of revenue to bus management. A met-heuristic algorithm, G.A and L.P model were used to optimize bus scheduling for efficient transportation. To achieve this, travel demands for peak and off-peak seasons at the two campuses of FUTMinna, Nigeria were obtained using 4 numbers of CCTV cameras located at strategic positions. Data were analysed using the design travel times of 40, 50 and 60 minutes considering traffic and road conditions using 19 numbers of 18 seater bus, 11 numbers of 35 seater bus and 15 numbers of 60seater bus capacities buses with15 minutes departure time. It was observed that with N100/head of revenue charges, a total of N185,000/day corresponding to 231 trips would be achieved during off-peak season to convey 2,562 students, and this amount would increase by 289% at peak season with very little or no delay to move 4,411students travel demand.
