During transport operations, even under normal operating conditions, the loading unit is subject to inertial forces, which may cause deformation of the unit, and in extreme cases, its disintegration. Stretch film wrapping is the most commonly used method of securing a load unit. This paper presents a new simplified simulation model of a class A load unit, with a layered structure, secured with stretch film. Between the layers of packaging, stick-slip friction was applied. A method of estimating the containment force was also proposed. This model can be used to pre-determine the number of film layers necessary to ensure load stability. Simulations can reduce the amount of film used and the number of stability tests performed experimentally.

This study examined the effectiveness of para-transit transport activities by identifying the socioeconomic characteristics of both the passengers and drivers of public transport and the factors confronting their operation. It utilised primary and secondary data. A purposive sampling technique was employed which entailed the identification of all the motor parks, the selection of buses, minibuses and cars at the motor parks, major bus stops and conducting a survey using a structured questionnaire cum interview. Questionnaires were administered to 354 respondents to obtain information about their socioeconomic, trip characteristics and the unconventional public transport operations, of which a total of 312 questionnaires were duly completed and returned. Data collected were analysed using simple descriptive techniques and correlation analysis. The results showed that the majority of the passengers (61.4%) were within the 21 – 30 years age bracket while 43.7% of the drivers were within the 31-40 years age bracket, the patrons and the operators of the public transport are predominantly low-income earners as large proportion of the passengers (42.1%) earned below ₦10,000 per month while 46.9% of the drivers earned between ₦10,001 and ₦20,000 per month. The results of the correlation analysis indicated both the drivers’ and passengers’ perspectives, factors such as public transport conditions, road quality and drainage system are highly correlated between their paired variables. Hence, effort should be made by the government and public transport operators to improve the transport infrastructural facilities in the study area.

W pracy zaproponowano definicję jednego ze wskaźników efektywności wymiany towarowej w makroskali. O stopniu takiej efektywności danego sektora, tu transportowego, decyduje zwykle relacja nakładów i wielkości produkcji. Zależność tę można otrzymać przy wykorzystaniu makroekonomicznych modeli wymiany dóbr. Jedną z propozycji w tym zakresie zawarto w niniejszej pracy.

This paper includes a definition of the indicator of the effectiveness of spatial trade on the macro scale. The degree of efficiency of a given sector, for example transportation, is determined by the relation of production and its cost. This relationship can be evaluated by various models of spatial economies. One of the possible way is considered in this study.

Freight market passenger cars in Poland is highly competitive. A large number of competitors makes it a competitive advantage to determine even small differences in prices of transport services offered. In this article author's goal is to develop methods to optimize the cost of transport operations in the selected company. Objective was achieved through the analysis of the logistics chain (transport) in the company's proposal Adampol SA and optimizing of loading and unloading operations, leading to lower their costs.

Real-time transit management systems that can inform the public about transportation options and availability are gradually being deployed in many parts of the world. While many larger cities have been able to provide this information on web sites or through automated telephone systems for several years, smaller municipalities often lack the resources to develop their own transit management systems. Addressing this issue as a joint effort, transportation agencies in the multi-state North American CARS Program have cooperatively developed a real-time, multi-modal transit tracking and incident reporting system called Modes. Modes builds on the CARS road condition reporting system developed by 17 transportation agencies in North America. Modes extends the CARS software to include ferry, bus, and passenger rail services to the basic highway network information it manages. Modes was initially created to track the Alaska Marine Highway System's extensive ferry system and has been successfully applied to New England's popular Acadia National Park bus tracking system, three bus systems in Maine, 13 bus systems in Idaho (in progress), three bus systems and a light rail line in the Sacramento, California area (in progress), as well as the Amtrak Downeaster and Capitol Corridor rail lines.

Multimodal transport implementation allows connecting the point of origin and the point of destination in an optimal way. The goal of multimodal transport is to maximize the efficiency in connecting the economic elements of various traffic branches, i.e. their operations related to transport and communications, thus positively reducing the inventories of raw materials, semi-products and end products with the aim of increasing the balance in the overall economic system of a country. The development of multimodal transport and good organization of the traffic system make it possible to increase the existing and to generate new freight flows that would result in positive effects on the import-export balance.
