In the article the theoretical basis for calculating the productivity of the vehicle and determination of the rational distance whileorganizing the cargo transportation with the change of trailers is offered.
The problem of the automobile course stability is considered. The change of the car steerability based on the analysis of non linear bicycl model is analyzed. Generalized dependence determining “the steerability curve” is obtained. Conditions which caused the loss of stability with increasing speed while moving within the constant radius circle regarding the bifurcation set are analyzed.
This paper emphasizes the need of fewer cars use. With the help of current state and the optimal level of product engineering needs of the selected car comparison, setting its overproduction, environmental impacts are quantified, also environmental and economic benefits of fewer cars using are outlined. This paper is also looking for innovative analysis of vehicle downtime. With the help of simple calculations based on continuous recording of the selected parking area analysis value of stoppageness of product and selected phase of its life cycle was implemented. Description of its redundancy is based on stocks theory, for which assistance need for cars with aid of logistics chains for these products has been written.
The paper presents a growing threat to the natural environment caused by the avalanche growth in the number of trucks and cars within the urban areas and beyond their borders. Based on the example of the Szczecin agglomeration - located at the crossroads of the east-west and north-south transit routes - selected harmful components associated with the use of trucks and their negative impact on the human lives and functioning of the ecosystem in Poland have been discussed.
