  • Agricultural Aviation a Strategy for Sustainable Food Production in Nigeria- Lessons from Brazil

    This paper presents a sweeping comparison of Nigeria and Brazil on their agricultural development performances with emphasis on agricultural aviation. Brazil is the fifth largest country in the world with 207.7 million people (2017 estimate); whereas Nigeria is the most populous country in Africa with 188.7 million people (2017 estimate). Both countries were known to have good soil which enhances agriculture but at different level of tilling. However, Brazil has outperformed Nigeria most especially in agricultural development with the approach of agricultural aviation, and has earned world status; while Nigeria still struggles with low agricultural productivity with old technological involvement. Brazil has large land mass with over 31% of land used in tilling. This study examines the use of aviation in agriculture which increases the productivity of farm produce in Brazil, and with a view to identifying the lessons for the improvement of agricultural development in Nigeria. This comparative study finds out lessons Nigeria can derive from Brazil in pursuing a sustainable agricultural development through suggestions regarding agricultural aviation.

  • Perception of Airport security and safety of international passengers a study Murtala Mohammed International Airport in Nigeria

    There had been an increasing security and safety concerns at international terminals since the September 11 incident in the US. In this regards, most related studies seems to be biased towards the developed economics preparedness to enhance and avert possible disaster encountered at the US. However, with the increasing threat being posed on a daily basis on African international terminal especially the Nigerian airport with the rise of Boko Haram and other emerging insurgents threats. This study seeks to examine the perception of international passenger on the safety and security of the Nigerian airport terminal. The methodology involves both the qualitative and the quantitative methods. The data is analysed with descriptive and inferential statistical analytical techniques. The study reveals there is a significant relationship between airport passenger perception of safety and enhanced security level at the airport. Also the passenger nationality status also influences the level of security procedures at the Murtala Mohammed International airport.

  • Analysis of Road Accidents in Bangladesh

    Recently road accidents are regular occurrences in all over the world. With the growth of motorization, urbanization and number of road users, the number of accidents and fatalities on road are increasing with the passage of time. In Bangladesh, thousands of people die every year due to street accidents. Most of the road accidents take place in the urban areas and in the highways. Proper and rational rates of accidents and corresponding trends are required to understand or judge the situation accordingly. In this paper, an investigation has been done to evaluate the rate of road traffic accidents and fatalities trends in terms of total number of accidents per year, and total number of registered vehicles per year using police reported accident data. Here, investigated results show that the proportion of accidents and fatalities from year 2010 to 2016 is approximately 1. It is really alarming situation in Bangladesh for increasing the number of fatalities with the equal number of accidents. Besides, number of fatalities is greater than number of accidents (equal to 2027) in the year 2014. The rate of accident, fatality, injury and causality is increasing in the year from 2014 to 2016 under the calculation of excluding motor cycles compared to including motor cycles.

  • Intermodal Terminal Design for Autonomous Freight Transportation Systems

    This paper investigates the design and operation of an intermodal terminal for Underground Freight Transportation (UFT) system. UFT is considered as a new mode of freight transportation that uses pipelines for transporting freight between two intermodal terminals. The load size and route length of the UFT system can be variable depending on the purpose and specifications of the project. In this paper two sizes of loads and two route lengths are considered to show that the terminal design and operation are independent from route length and load size. Each UFT route starts at the Port of Houston where shipping container or pallet size loads will be delivered to the UFT system. The short-haul route ends at a proposed intermodal satellite terminal outside Houston and the long-haul route terminates in a proposed intermodal inland port in Dallas. This paper develops inclusive equations to estimate the operational attributes of the UFT intermodal terminal. These attributes include operational headway, system flow, fleet size, and number of handlers/forklifts required in operation of the terminal. Based on the terminal operation requirements, a typical design for a UFT intermodal terminal is presented. In addition, the loading/unloading process and the freight circulation scheme are discussed. Although, this schematic terminal design and operation are for shipping container loads, but the same concept can be applied to smaller scale loads such as pallets.

  • Air pollution dispersion models-special reference to input parameters and application in sustainable urban planning

    Air pollution dispersion models have different applications including in sustainable urban planning. It is a model showing picture of reality and is widely used to make predictions thereby solve problems and make compatible strategies for the management of specific environmental problems. The output of a model is precisely dependent on source strength of pollutants, meteorology, topography, dispersion coefficients, and plume rise and so on so forth. An effort has been made in the present paper by the authors to precisely estimate the source strength, dispersion coefficients, plume rise etc along with type of air diffusion models and their relevance on urban planning.

  • Factors Affecting E-bike Mode Choice in a Medium-sized Chinese City

    Chinese medium-sized cities have different travel characteristics compared to big cities. And as the rapid development of e-bike in China, some problems such as transportation safety has been discussed by scholars. This paper examines the factors affecting residents’ travel mode choice in medium-sized city using travel survey data collected from residents in Zhongshan city. An estimated nested logit model of travel mode choice reveals that: (1) Older people prefer to travel by e-bikes than younger people. (2) Residents who own e-bikes tend to choose e-bikes, while not other vehicles. And the profession of people who prefer to travel by electric bicycle the white collar and blue collar. (3) About the attitude of Zhongshan residents to choose the way of transportation, the e-bike is considered the least safe, and electric bicycle users are concerned about the improvement of bicycle lanes. (4) The influence of built environment in the place of origin and the place of destination on the choice of e-bikes is different. (5) There is a substitution effect between e-bikes and traditional bicycles. The results strongly suggest that e-bike is a kind of important transportation in Chinese medium-sized city, and it is likely to regulate e-bike by transportation policies.

  • Built to Last? The Changing Role of Ocean Transportation Intermediaries: Disintermediation and Reintermediation

    Introduction Ongoing changes in the maritime container shipping industry and the introduction of new technologies are dramatically changing the role of the ocean transportation intermediary (OTI’s). Full service intermediaries can secure space with ocean carriers, offer customer transloading, consolidation, trucking, freight forwarding, customs brokerage and a range of other services that are crucial to the movement of goods. In high volume markets such as the Transpacific trade lane, the role of intermediary has grown as the liner shipping firms utilize mergers, alliances, vessel sharing agreements and mergers in an effort to remain financially viable. Approximately 42% of Transpacific moves are handled by NVOCCs at the time of this writing (Mongelluzzo, 2016). Delayed vessel calls, poorly aligned chassis supply and changing carrier alliances have provided an opening to OTI’s to sell themselves as supply chain experts who help their shipper customers navigate the complexities of international shipping by providing more value added services than the liner shipping operators (Landon, 2015). As the need for skilled intermediaries has grown, new online platforms from advanced technology firms have the potential for disintermediation- ‘cutting out the middle man’ from transactions for a variety of core ocean freight processes like procurement, forwarding, and supply chain visibility (Steele, 2009). This has long been predicted since the advent of the Internet but has only now reached the critical mass of advanced technology programming and large scale equity investment that will lead to a similar software revolution in logistics as has transformed other aspects of the economy. The advent of new freight technologies will most likely lead to the demise of many OTI’s who are not scaled to be able to utilize the software but also possibly create the formation of new skilled intermediaries (i.e. reintermediation) that create markets and enhance value to customers through innovations to produce…
