AN ASSESSMENT OF THE EFFECTS OF ON-STREET PARKING ON TRAFFIC FLOW IN FEDERAL CAPITAL CITY (FCC), ABUJA, NIGERIA

Farah B.S. — 2022-06-03

Transport problems are very common in the Central Business District of Nigeria Cities as a result of the growing concentration of population, rapid urbanization and economic activities of certain point of the world. Parking and traffic congestion is synonymous to each other because failure to meet parking demand of people in a city lead to on-street parking that results to traffic congestion. The availability of less space in urban areas has increased demand for parking space especially in central business area especially city like the Federal Capital Territory (FCT), Abuja. This study aim to assess the effects of On-Street parking on traffic flow within Federal Capital City (FCC), Abuja. The data used were collected through secondary and direct field survey on motorists, Federal Capital Development Authority (FCDA), Parking Vendors, Inventory survey, while the secondary data were sourced from records of the vendors, FCDA authority etc. The analysis of data collected revealed that provision for parking facility is seriously lacking within FCT, which shows that parking facility is only provided at NICON junction while all other locations lacks parking facilities. Taxis are the major culprit of On-Street parking within the FCT with about 52% compared to other category of vehicles. It was also revealed that accident, jam/congestion and reduced speed are the major effect of On-Street parking within the FCT. Finally, it was recommended that off-street parking facilities/spaces should be provided at designated areas of FCT. Strict enforcement of traffic rules and regulations and effective traffic management system should also be put in place to eradicate On-Street parking in the FCT.

ON-STREET PARKING AND TRAFFIC CONGESTION AROUND KADUNA CENTRAL MARKET

Bobai F.D — 2022-06-03

This study examined the challenges of on-street parking along Kaduna central market. The study used primary data as the major source of data. One hundred and ten questionnaire (110) were administered to respondents in the study area. Simple descriptive statistics such as tables and percentages were used for analysis. However, the study discovered that 45% of the congestion along the study area is caused by on-street parking and other economic activities going on along the route. It was recommended that bus stop for commercial motor and parking lots for private motors that are provided should be used by all vehicle operators in the study area. The study concluded that off-street parking spaces should be provided especially along those roads where there are concentrations of economic activities.

ADDRESSING THE ISSUE OF TOUT (AGBERO) TOWARDS SUSTAINABLE ROAD PUBLIC TRANSPORT IN IBADAN

Ajiboye A. O. — 2022-05-21

One of the challenges facing the public transportation development of Nigeria has been the significant birth of transport tout called ‘agbero’. Therefore, this study was conducted to address the issue of tout towards sustainable public road transport in Ibadan. The study adopted both purposive and simple random technique using a well-structured questionnaire to elicit information on the issue of agbero. Three (3) commercial motor parks and seven (7) bus-stops were purposively sampled. The respondents in this work were Nissan Micra taxi drivers and intra-city public bus drivers, and commuters of both intra-city and inter-city public transport selected from motor parks and bus-stops, respectively. The respondents were selected through a simple random sampling technique. Two hundred (200) questionnaire were distributed to various respondents and 192 retrieved. The findings of this study revealed that inadequate access to economic means remains the main reason for engaging in the work of an agbero. Furthermore, the result showed that agberos were part of road administration in Ibadan; they averagely earn more than a university graduate Violent extortion is their main activity among others while the government’s measure in curbing the menace of agbero in Ibadan is gradually yielding results. This study, therefore, recommends that the governments should create employment opportunity for youths to channel their energies to a productive enterprise. Education should be mandatory while attention should be given to graduates. The law should serve as a safeguard against an unlawful act of road extortion and other menace caused by agbero. Lastly, the operation of transport unions should be reviewed by the local and state governments through effective dialogue with stakeholders and rendering of proper accounts by the executives and parks’ managers.

CONSTRAINTS OF USING PEDESTRIAN BRIDGES ALONG LAGOS-IKORODU EXPRESSWAY

Asaju J. A — 2022-06-03

Walking has been the dominant transport mode for many centuries in all countries. Before industrialisation took place, there were some alternatives such as riding of animals, horse drawn carriages and water transport, but walking must have been by far the most substantial transport mode. It is one means of movement that comes by instinct naturally, without involving any learning process. Pedestrian bridges however are structures made for allowing pedestrians to cross a street, road, highway without being exposed to the risks of vehicle accidents. It is one of the structures that remove pedestrians from vehicle roadway. This study examines the various constraints encountered in the use of pedestrian bridges along Lagos–Ikorodu expressway with fifteen (15) pedestrian bridges in its entire 24.5km road network. Direct observation through reconnaissance survey was employed for the purpose of this research while Global Positioning System (G.P.S.) was used to obtain the coordinate and pattern of distribution of pedestrian bridges on the corridor. Structured questionnaire were also used to obtain the perception of respondents on the constraints of the usage of the bridges. A total of 514 copies of questionnaire were administered using Yammane method of sample determination while stepwise regression analysis was used to analyse the data. The stepwise regression results showed that distance between the bridges 53.8%, inconveniences 11%, height of the bridges 7.1%, poor lightings 2%, lack of enforcement 1% and bad state of the bridges 0.4% are the major constraints faced by pedestrians contributing 75.3% in the variance. The study however recommended the provision of pedestrian friendlier bridges, more awareness campaigns in schools and public places on their usage, installation of elevators to ease the usage and solar energy to lighten up the bridges among others.

AN EXAMINATION OF CAUSES AND EFFECTS OF TRAFFIC CONGESTION ALONG IYANA ISASHI- AGBARA SECTION OF BADAGRY EXPRESSWAY

Olorunnimbe R. O — 2022-06-03

This research had undertaken an examination of the causes and effects of traffic congestion along Iyana Isashi-Agbara section of Badagry expressway, Lagos. This was done for the purpose of solving the traffic congestion along the study area. The study adopted quantitative research techniques using field observations and the parameter measurement, including traffic count and flow analysis. The findings from this study shows that the inadequate road capacity, absence of bus stop laybys and motor parks, on-road bus parking and poor intersection design, are the major problems affecting the free flow of traffic and prolonged travel delay along Iyana Isashi-Agbara Section of the Badagry expressway. More so, the presence of the traffic control officers is not adequate in combating the challenges of traffic congestion in the area. The study therefore suggested among other solutions the provision of motor parks, laybys, improved intersection design and control, increase in Lagos State Traffic Management Authority (LASTMA) personnel and control facilities as well as the speedy completion of the ongoing 10 lanes with Bus Rapid Transit (BRT) and Light Rail facility on the Badagry Expressway.

AN ASSESSMENT OF TRANSPORTATION ISSUES AFFECTING HEALTH SUPPLY CHAIN IN NIGERIA

Abdul-Azeez I. F — 2022-06-03

The nature of the transport system in Nigeria has made it inordinately difficult and extremely expensive to transport goods such as vaccines, essential drugs and other medical supplies across the length and breadth of Nigeria. These issues require immediate attention to develop a responsive transportation system which will allow for a more effective and reliable health supply chain system. This paper, therefore, focuses on the assessment of the current issues affecting the road transport system in Nigeria and how they impact the health supply chains. This conceptual research captures the findings, thoughts, experiences, views of researchers and professionals in the field of transport, supply chain, and health logistics. Published literature such as peer-reviewed articles, case studies, reports and similar documents were reviewed. Transport issues affecting health supply chain were identified under three major categories – infrastructure, vehicle, and operation - and strategies to strengthen them for optimal transport performance were proposed.

THE EFFECT OF ROAD TRANSPORT EMISSION AND ITS RELATED HUMAN HEALTH DAMAGES ALONG TRAFFIC CORRIDOR IN IKARE, AKOKO NORTH EAST, ONDO STATE

Odesanya J. F — 2022-06-07

Road transportation is a vital segment of the society without which movement may be very difficult. However, every automobile movement in space is without its negative externalities of which are air and noise pollutions. This study examines the health effects of automobile emission on those that subsist along traffic corridors in Ikare, Akoko North-East LGA of Ondo State. Survey research design was used to evaluate the effects of air and noise induced pollutions emanating from road transport corridor on those that carry out their daily businesses on the selected corridor. Variables studied on air-borne health effects are: coughing, breathlessness, nasal discharge, throat irritation, asthmatic conditions while for noise induce health pollutions are: irritations and discomfort, annoyance, stress, sleeplessness, disruption to effective communication and headache. Using descriptive statistical method, it was discovered that 13.43% of sampled respondents cough often, 3.48% have high level of breathless, 7.96% of the respondents have high nasal discharge, 8.46% of the respondents have high throat irritation, 3.48% of the respondents have high asthmatic conditions while for noise induce pollutant, 17.91% feel they are highly irritated and discomforted, 31.84% feels they are highly annoyed, 21.39% felt they are highly stressed, 11.44% experience high level of sleeplessness,14.43% felt noise cause a high disruption to them during communication, and another 24.88% says they highly felt headache. It is recommended that proper legislative work be done to stop automobiles that do not meet up with permissible emission recommended standard from operation.

AN ASSESSMENT OF ROAD TRANSPORT INFRASTRUCTURE PROVISION IN TRAFFIC MANAGEMENT IN KADUNA METROPOLIS

Akinfolahan J. — 2022-05-26

Application of various Intelligent Transport System (ITS) and Road Transport Infrastructure (RTI) provisions are essential component of urban traffic management. This paper considered the scenario in Kaduna metropolis which cannot be left out. This is as a result of her ever increasing vehicular traffic in the metropolis. This paper therefore attempts an assessment of the types, state, and functionality as well as distributions of both intelligence transport system and road transport infrastructure (RTI) in management of traffic movement within Kaduna metropolis. The Primary data was gathered through questionnaire administration using stratified random sampling technique and personal interview, while secondary data was gathered from published journals. Inventory of the road infrastructure provided was identified in all the location of study within the metropolis. In all, a total of 400 questionnaire was administered but only 380 respondents were successfully retrieved. The result showed spatial distribution of various road transport infrastructure such as traffic lights, road sign, road markings, zebra crossing, lane departure signs speed limits control, pedestrian warning signs, route direction signs across the city. Meanwhile, CCTV camera and Electronic Chart Display and Information System (ECDIS) are not available. However, the adequacy of ITS automated gadgets such as CCTV camera, ECDIS and Pedestrian warning signs was rated poorly by respondents while other ITS facilities/gadgets such as road signs, speed limits, road markings, zebra markings, lane departure warnings and traffic lights were available in the study location in Kaduna metropolis but not adequate. The results shows the rating of RTI as fair, good and very good respectively while the majority of respondents agreed that RTI are far from being excellent. The state of ITS result shows that most of the ITS target are in fair state while further studies carried out on challenges facing ITS are irregular in lack of power supply, vandalization, poor maintenance, and poor replacement policy respectively. Conclusively, from the findings it was therefore recommended that there should be deployment of adequate and even distribution of efficient automated intelligent transport system that will complement the road transport infrastructure in managing and coordinating the flow of traffic such as signal control systems, parking guidance systems, travel and traffic information system, public transport priority system, and lane management

Ajala A.T — 2022-06-03

Efficient Urban mobility is a function of available transport infrastructural facilities such as roads. This study aims at examining the effect of road condition on transit mode choice of urban travelers in Ota town, Ogun State, Nigeria by assessing transit mode, road condition and established effects of road condition on transit modal choice of urban travelers. A sample of 0.2% of the estimated population of Ota was selected randomly from five traffic zones. Household survey was conducted using structured questionnaire, 350 questionnaire were distributed and retrieved. Data obtained from the survey was analysed using descriptive statistics and analysis of variance (ANOVA) with the aid of Statistical Package for Social Sciences (SPSS) version 23. Findings from the analysis revealed that 75.4% of the trips are made using public transport mode. The study concluded that there is a strong positive relationship between the condition of road facilities (sig. 0.000, F= 854.723at p =0.05) and choice of travel mode. The study therefore recommends development of road infrastructure development policy that will promote regular road construction and maintenance as well as ensuring increased private sector investment and financial participation in the road development in the study area.

CAUSES OF FAILURE IN DOMESTIC AIRLINES IN NIGERIA AVIATION MARKET

Uhuegho K. O — 2022-06-03

The purpose of the study was to quantitatively determine the primary factors that have contributed towards the collapse of domestic airline businesses in Nigeria. A quantitative explanatory correlation research design was used to examine failure factors based on airline sustainability factors. A sample size of 113 participants was used in the study, which represented aviation stakeholders. Quantitative analysis was conducted using Statistical Software, SAS. The study ranked five top failure factors such as ownership and management structure, economic conditions, lack of supportive economic policy, financial performance and operational efficiency and airline leadership effect using highest sum and means. The result revealed that leadership plays a significant role in the extent to which the various failure factors can predict the failing of a commercial airline in Nigeria. The study concludes that prevailing economic condition, policy summersault (Failure) and ownership and management structure are factors that require attention of leadership if failure of airlines is to be mitigated. Therefore, the study recommends that there is need for adequate technical knowledge of air transport system and air transport environment for airline leadership as a prerequisite for obtaining air operator certificate from Nigerian Civil Aviation Authority.

AN ASSESSMENT OF VEHICULAR EMISSION FROM THE EXHAUST OF MOTOR VEHICLES IN ZARIA URBAN AREA, NIGERIA

Anyanwu N.O. — 2022-06-03

This study was aimed at assessing the amount of vehicular emissions from the exhaust of motor vehicles in Zaria Urban area. Data on emission levels for carbon (II) oxide (CO), carbon (IV) oxide (CO₂₎, nitrogen (II) oxide (NO) and hydro carbon (HC) for this study was collected via the use of Automotive Emission (Multi-gas) Analyzer. Also, a total of 331 vehicles were sampled and data was collected at the identified high traffic points in the urban Zaria area. Results of this study indicated that diesel engines emit more NO (900.2ppm) than gasoline vehicles (500.11ppm). For HC, diesel vehicles emitted 2338.65ppm in comparison to the 2674.94ppm emitted by gasoline vehicles. The average vehicular emission for all the vehicle types shows that the mean amount of CO from motorcycle was 53687.50ppm which exceeded those emitted by other vehicle types. In the case of CO₂, buses emitted 87200ppm, more than other types of vehicles while trucks emitted 902.20ppm of NO, much more than other vehicle types. Also for HC, cars emitted 2772.40ppm representing the highest amount of HC emitted for all vehicle types. Furthermore, a comparison of the emissions recorded against National Environmental Standards and Regulations Enforcement Agency (NESREA) standards indicated that the recorded levels of HC and CO exceeded the acceptable limits as set by NESREA. Based on the findings of this study, the adoption of emission control technology, and the use of cleaner vehicles and fuels among vehicle owners in the study area is strongly recommended.
