This paper focuses on a solution to the finance restrictions that obstacle the development of railways section in Sudan. Sudan is a big country with an area estimated at more than 1,800,000 km2. It owns variety of natural and other resources. The transportation system in Sudan specially railways suffers a lot of restrictions that affect its contribution to the national economy. Sudan railways is one of the longest railways in Africa with about 5,000 km. Railways were the earliest mechanical means of transport to be introduced in Sudan. The construction of the first railway line started in the last decade of the Nineteen century. Railways have been playing a significant role in transportation for long time. However, railways in Sudan lack passengers’ trains recently. Moreover, the capacity of freight trains is enough to meet just 10% of needed capacity. Also, most of the rails are very old and exceeded their expire date; and as the result a lot of derailments had been occurred. Also, most of the rail on the western lines are not suited to all of the diesels. Moreover, most sleepers are creosoted wood which differ from that used in the neighboring countries that use steel or concrete. And to overcome all these issues, there is a huge need of finance. However, lacking of finance is one of the main restrictions that face the development of railways section in Sudan. And, in spite of that, the Build Operate-Transport (BOT) approach could be the best option to deal with the current situation that faces railways section in Sudan. Build-Operate-Transport Approach (BOT) is a well-known method of initiating, financing and managing public capital projects by private section for specific period of time and then transfer them to the public owners. The idea of the approach is to give the private…
With the rapid development of social economy, the number of family cars has entered a period of rapid growth and the consequent urban parking problem has become increasingly prominent, gradually becoming one of the problems facing cities in China. The regional planning of parking spaces can expand the number of parking spaces within a unit area. Therefore, considering safety, convenience, efficiency and other factors, how to maximize the number of parking spaces is the key to solve the parking problem. Based on the triangle division of Abdelfattah model and the analysis of PSU planning theory, the planning of mall parking lot is more realistic. This kind of planning maximizes the number of parking spaces on the basis of greatly increasing the flexibility of vehicle entry and exit, which is more conducive to our life.
This paper presents guidelines to the needs and restrictions that affect the growth of Sudanese livestock exports resulting from the weakness of transportation section. Sudan has a huge livestock population. The livestock has a great contribution in the local economy. The production of livestock in Sudan is increasing effectively in the recent decades. Also, the contribution of livestock to exports has witnessed a gradual growing in the past few decades. The weakness of road and transport infrastructure, however, is affecting the growing of livestock export in Sudan. The livestock production is concentrated in rural areas that far away from the main roads and unconnected to them by paved roads. The road quality, in Sudan, is very poor. The infrastructure does not cover most Sudanese geographical area especially agricultural and livestock areas. Also, the cost of transportation is very high in comparison with international cost. Moreover, road maintenance is very weak and not cover all roads networks. And, there is a lack of finance for new road projects. This study finds out that the roads’ situation in Sudan is not helping the current growing progress of livestock exports and seriously declines that growing.
Evaluation of undergraduate Logistics & Transportation Management curriculum change from traditional lecturing to student-centered Problem-Based Learning (PBL) active learning environment
Problem This paper presents the outcomes of the Problem Based Learning (PBL) methodology implementation in the undergraduate Logistics & Transportation (L&T) Management course at the Federal University of Itajubá (UNIFEI), Brazil. The research explores a curriculum change evaluation by using Survey data from two stages, in two semesters of the L&T course, with different PBL scenarios and students. L&T course addressed several concepts of Logistics Management and the PBL approach enpowered students to self-learning, citical thinking, social and process skills. It was demonstrated that the majority of the students, over 91%, appreciated the benefits of PBL based curriculum in both semesters, with positive evaluation in all course dimensions. To support the conclusions of the study, special attention was given to the development of the questionnaires. The first stage, the pilot questionnaire, had a set of 21 scaled and structured questions, covering the course concepts and learning objectives. The second stage questionnaire was redesigned to a new set of 15 questions, modeled to three constructs by Factor Analysis, keeping up with the reliability and validity requirements.
Performance Analysis and Classification of the Ports in Gulf Countries Using Data Envelopment Analysis
The study assesses relative efficiency and performance characteristics of the major ports in gulf countries using data envelopment analysis (DEA). Ports play key role in economic activities of these countries. The study reveal that technical efficiency of the ports in the region varies widely with mean constant and variable return to scale of 67.5 and 91 percent, respectively. Port Jabel Ali in UAE is identified as the benchmark for most of the inefficient ports indicating that the inefficient ports of the region should follow operational strategies of Port Jabel Ali. Also, all the inefficient ports of the region demonstrate increasing return to scale implying that their performance may improve with the scale of operation. Policy makers may consider investment to enhance operational scope of these ports.
This paper assessed the Transport and Logistics Education as a University undergraduate programme being offered by some selected universities in Southwestern Nigeria. The specific objectives of this study are to examine the programmes of transport and logistics education with a view to understand areas where they are lagging behind across the selected Universities. Secondly, to determine those attributes that may facilitate qualitative education, not only in transport sector; but also at improving Nigerian universities education system. The total of 250 recently graduating students of the selected universities were randomly sampled and given both questionnaires and assessment form which covers six major subjects in the areas of Logistics and Transport. Descriptive analytical technique was used to achieve the first objective and Principal Component Analysis (PCA) was used to factorize fifteen identified variables and reduced it to eight principal components considered to facilitate qualitative education in Transport and Logistics Education in Nigeria. The results showcased the areas of strength and weaknesses of the selected schools and principal factors that must be available for qualitative logistics and transport education system in Nigeria.
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.
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.
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.
