On September 25, 2015, UN member states adopted the 2030 Agenda for Sustainable Development. It contains 17 Sustainable Development Goals (SDGs). Two SDG targets are directly transport-related. Target 3.6: By 2020 to halve the number of global deaths and injuries from road traffic accidents. Target 11. 2: Aims to, by 2030, provide access to safe, affordable, accessible and sustainable transport systems for all, improving road safety, notably by expanding public transport, with special attention to the needs of those in vulnerable situations - women, children, persons with disabilities and older persons. There are other goals, the achievement of which is impossible without the development of transport. All SDGs related to transport are conventionally divided into 4 groups: safety, universal access, efficiency, green mobility. The purpose of this article is to review the dynamics of changes in the Republic of Belarus of indicators for achieving the goals of the universal access group.

The obsolesce and decay of rail transport infrastructure linking major seaports Cities to hinterland cargo origin and destination centers serviced via the seaports and the total lack of rail infrastructure connection between some hub seaports and the hinterland cargo centers in Nigeria induces enormous economic setback. Most rail routes from seaports to the inland container depots (ICDs) in all the geopolitical zones of the Country are currently inoperable. Government’s recent attempt to develop and make operable the rail routes is faced with funding challenges necessitating the need for a Public Private Partnership (PPP) approach in which government provides regulation and enablement while private sector operators fund the projects. This study was aimed at providing economic justification for private sector investment in developing, revitalizing and making operable, the rail-freight-corridors between hub-seaports and inland container depots in Nigeria. It estimated the operator-benefits and profitability potentials of investment in each of the ten rail-freight-corridors consisting of existing but inoperable and proposed rail routes from Lagos, Port-Harcourt/Onne, Warri and Calabar seaports to the Inland container depots in different geopolitical regions of Nigeria. Secondary data on the import and export (cargo generation) capacities of each of the ICD regions to and from the respectively connected hub-seaport were obtained from the Nigerian ports authority statistical report covering a period of two years (2018 – 2019) based upon which the annual expected revenue earnings of the operators (investment) were estimated as a product of the total annual TEU handled by each route and the price of delivering per TEU from the seaport to the ICD region. The cost of investment in developing and operating each rail-freight-corridor as determined in previous studies for the Nigerian Shippers Council for the same period were also obtained. Benefit-Cost-Ratio (BCR) and Net Present Value (NPV) tools were used to estimate the operator-benefits and profitability potentials of each rail route within the period using 10% interest rate. It was found that six of the rail routes have BCR > 1; and NPV>0; implying higher operator-benefits over costs within the period. The rail-routes from Lagos seaport to Gombe and Bauchi; Warri seaport to Aba; and Calabar seaport to Kano have BCR

With vast range of applications in real life situations, the Vehicle Routing Problems (VRPs) have been the subject of countless studies since the late 1950s. However, a more realistic version of the classical VRP, where the distribution of goods is done from several depots is the Multi-Depot Vehicle Routing Problem (MDVRP), which has been the central attraction of recent researches. The objective of this problem is to find the routes for vehicles to serve all the customers at a minimal cost in terms of the number of routes and the total distance travelled without violating the capacity and travel time constraints of the vehicles, and it is handled with a variety of assumptions and constraints in the existing literature. This survey reviews the current status of the MDVRP and discuss the future direction regarding this problem.

Industrial engineers always want to implement optimization techniques in all activities performed in an organization, which is only possible by synchronizing multiple activities of each department, and combining it in a way, which is optimized as per efficiency, effectiveness, productivity and profit are concerned. Organization plant managers and logistics providers have long been dissatisfied with extensive waiting times and severe on-site traffic congestion. This research paper highlights activities of logistics management in this organization which covers activities like determination of supply chain driver affecting logistics and supply chain management of an organization, analysis of current vehicles freights which particularly involves number of freights per day, checking how effectively collection plan needs are fulfilled by current vehicles running, implementation of new techniques to improve present working system, scheduled such that the total weighted tardiness is minimized, initiation of practices which organization has to do for withstanding sustainability in logistics management, estimation of cost saving from implementation of new techniques and checking feasibility of conducting these activities repetitively in long run.

Sustainable transport is about taking holistic approach by considering economic, society and environment along with the mobility and accessibility requirement of people. In case of Greater Mumbai, there is presence of inequity in provision of transport infrastructure and service. The first part of paper arrives at sustainability indicator by means of compounded economic, social & demographic, land use and transport access indicators. The second part of paper measures the extent of sustainability in various wards of Greater Mumbai. It was important to study the extent of sustainability by measuring the gap between sustainability & HDI indicator and sustainability & transport access indicator. In terms of transport access, the gap between transport access indicator and sustainability indicator is present in most of the wards of Greater Mumbai. The overall result proves that there is urgent need to address the provision of transport access in most of the wards of Greater Mumbai. Purpose: The main purpose of this paper is to arrive at sustainability indicator and to measures the extent of sustainability in various wards of Greater Mumbai in transport. Methodology: The paper arrives at sustainability indicator by developing compounded economic, social and demographic, land use and transport access indicators. In order to calculate economic, social & demographic, land-use and transport access indicator considered normalized value of each indicators derived from maximum point normalization across all wards. Finally equal weighted average of all indicators was taken to calculate the overall sustainability indicator. To measure the extent of sustainability in various wards of Greater Mumbai was done by comparing aggregate sustainable indicator with HDI indicator and transport access indicator. Result: The overall result proves that there is urgent need to address the provision of transport access in most of the wards of Greater Mumbai. The theoretical contribution: This paper arrives at sustainability indicator by compiling economic, social and demographic, land use and transport access indicators. Practical implications: This paper calculates ward level sustainability in Greater Mumbai and identifies the need to make provision of different transport infrastructure.

This paper outlines a multi-dimensional user-oriented performance metrics approach in evaluating the operation of the terminal airspace system to aid in the airport and airspace planning and decision making. Safety, delay and predictability metrics contribute to the analytical framework. From the findings, the occurrence of air incidence has a high severity level at departure, and arrival phases of flight, higher likelihood at the radar room and much of the incidences were as a result of faulty equipment and inherent absence of modern airspace infrastructure. Also, in Lagos terminal airspace, the number of incidences has no close correlation with the level of traffic complexity. Total schedule arrival delay ranges from 1-392 minutes representing an average of 7.8-17.9 minutes per aircraft that arrived Lagos airport at that period. Besides, the total approach contact time ranges from 1-57 minutes, translating to 4.6-7.1 minutes per aircraft. However, variability in arrival time of 1-5 minutes is common from published airline arrival scheduled time. In the same vein, the variability of 1-5 minutes is common from approach contact times of aircraft. These figures indicate sound arrival predictability signature for Lagos airport. Also, departure time variability above 30 minutes is familiar from the ATC clearance time for the various routes under study. However, there is about or more 25% variability of more than 15 minutes, and this indicates possible inconsistency of predicting departure times from the times ATC clearance was acquired. Above all, the predictability of departure times in Lagos airport is weak compared to those of the arrival. Taken by it, this may be a sign of airspace congestion or ATC deficiencies at the Lagos airport. This is an indication of the lack of users' confidence in Nigeria's air transport industry to deliver just-in-time service.

There is no doubt that Coronavirus disease 2019 (COVID-19) pandemic has impacted negatively on global shipping and the effects are also being felt in the Nigerian shipping industry. Through review of extant literature, the effects of COVID-19 on Nigerian shipping industry with specific focus on port operations and Nigerian seafarers were examined. The findings revealed that lock down of the economy and restriction of movements in Nigeria presented a challenging situation for stakeholders in the shipping industry to fulfill their contractual obligations, import and export operations are hampered , Nigerian seafarers are mentally and psychologically disturbed as a result of lack of social support and extension of contract beyond the agreed contractual term with exhausting workload onboard with little or no support from the management who are more concerned about contract execution than the welfare of the crew onboard. However, it was recommended that living and working conditions of Nigerian seafarers onboard in this pandemic era should be given utmost attention by applying practical and pragmatic approach on issues bordering on facilitation of crew change, resupply, repairs, survey and certification and licensing of seafarers.

Widespread usage of emission free public transport is the preferred strategy in many cities to reduce a congestion and pollution from the road traffic. The trolleybus is a kind of urban public transport, i.e. a fully electric vehicle, which is considered as a promising tool to enhance the efficiency of public transport and to attain the goals of sustainable development and quality of city life. The operation control of service brake system and secondary brake system (the braking torque of traction electric motor) is realized with help of one pedal in the trolleybus. Thus, there are modes of the joint operation for these systems during the braking process. Authors focus on the development of rule-based algorithm for the blending control of traction electric motor and anti-lock braking system to enhance the overall braking efficiency of a vehicle. The mathematical model of the trolleybus braking dynamics was developed for this purpose. Test bench and ride tests on different road surfaces were carried out to determine the parameters of vehicle braking efficiency and to validate the developed mathematical model. The corresponding experimental data were used to analyse the efficiency of proposed rule-based strategy for the blending control of traction electric motor and anti-lock braking system of the trolleybus. As a result, the availability of proposed control algorithm is confirmed, which secures the required braking efficiency and provides a high braking stability of the vehicle.

Following the growing world population and associated need for increased transportation, there is a growing interest in some aspects of transport such as sustainability, to reduce CO2 emissions and reach climate objectives. Modern urban living is rapidly changing with new technological innovations, one of which is the possibility to integrate different electronic “on demand” services into one single medium. Public transport users need innovative, multi-applicative, multi-functional, safe and secure ticketing systems, easy to use. Concept of Mobility as a Service (MaaS) as an integration of various forms of transport services into a single mobility service accessible on demand is a new way of thinking about public transport. This paper focuses on mobility market transformation with main question how Mobility as a Service based on open source principles will impact the ecosystem.
