This paper presents the idea of the Local Area Navigation Systems (LANS) for automotive application in combination with standard GNSS navigation systems. The navigation system is based on four components: the widely available GPS, pseudolites located in areas where GPS signal is obstructed (tunnels, parking lots, city canyons), GPRS communication and supervisory informatics system. In this kind of system, reliable positioning is crucial. This article covers basic aspects of GPS single point positioning commonly used in navigation applications. Some information about differential positioning (DGPS/RTK) is also provided. A strong pressure is put on the application of pseudolite, its design and possible usability. This article presents authors own pseudolite design and the idea of pseudolite application to increase road safety in areas where standard GNSS signals are not available. The pseudolite presented in this paper is in the stage of development and testing. It is a device designed at the University of Warmia and Mazury in Olsztyn in cooperation with Canadian Center for Geodetic Engineering, University of New Brunswick, Canada. Different approach to the navigation in harsh environment is to move the source of the navigation outside of the vehicle and place it inside of the obstructions. It is much more efficient way to use in vehicles standard GPS receivers augmented with signals from the pseudolites, when the satellite signals are unavailable.
W artykule dokonano analizy transportu samochodowego jako źródła zanieczyszczeń środowiska naturalnego oraz hałasu. Zwrócono również uwagę na problem zużycia nieodnawialnych zasobów paliwowo-energetycznych oraz dużą liczbę wypadków drogowych. Wykazano, że głównym kierunkiem, który prowadzi do odwrócenia tych niekorzystnych zjawisk jest rozwój telematyki drogowej. Na podstawie przeprowadzonych badań ankietowych stwierdzono, że szczególną pozycję w tym zakresie zajmuje ciągła edukacja motoryzacyjna skierowana głównie do młodych kierowców, ale i całego społeczeństwa.

This article analyzes the motor transport as a source of environmental pollution and nosie. Attention was also drawn to the problem of consumption of non-renewable fuel and energy resources and a large number of road accidents. It was shown that the development of road telematics is the main direction that leads to the reversal of these adverse events. Special position in this regard is continuing automotive education aimed mainly at young drivers and also the whole society, was based on surveys conducted.
