Abstract The article includes an analysis of spatial and temporal possibilities of commuting to work by collective transport during the morning rush hours in Szczecin. This article focuses on transport accessibility by collective transport in Szczecin measured with the use of Geographic Information System (GIS) tools and General Transit Feed Specification (GTFS) format for exchanging public transportation schedule and geographic information. A public transport model includes journey sources who are people of working age and destinations which are different workplaces in Szczecin. The main objective of the article to determine places of the highest accessibility by collective transport within 1-minute period of time. The accessibility analysis for jobs and companies is made in Szczecin, as Szczecin’s public transport operator has published the GTFS format as the first in Poland. In addition, Szczecin has a very specific urban layout, separated by a river and connected by one (main communication artery) and the other smaller bridge for crossings between Lewobrzeżem and Prawobrzeżem. The analysis is to show the exact hour during which the largest number of citizens has the possibility to commute to the highest possible workplaces. The result shall depict interdependence between various components (space usage, time, individual), transport accessibility and a choice of a place having the best possible accessibility during the morning rush hours (Geurs & Ritseman van Eck 2001). The results are to be presented with the use of the cumulative accessibility and graphs.1.

Abstract
The article examined the possibility of using General Transit Feed Specification (GTFS) to identify deviations of public transport in morning hour traffic. Deviations in the functioning of public transport spanned in a radius of 30 minutes public transport travel time from the center of the city. The adopted travel time to the center is taken from a comprehensive traffic study performed in the city where indicated value of 27 minutes (comprehensive traffic study ...) is used as the average travel time of public transport. Diagnosis of deviations in the operation of public transport was taken on a weekday between 6:30 and 8:30 am at 5 min intervals. The results of calculations of time availability were made every 5 minutes and applied to each other and trimmed among themselves. Hence the contour line was established within isochrone of 30 minutes, with the identification of areas with 100% certainty of public transport access to the center of the city and areas of lesser public transport accessibility. The resultant isolines were measured against the population living in census districts, on the basis of which the areas of certain as well as uncertain 30 minute travel time to the center of the city were determined.

Impact of selected road investments on traffic safety

Abstract The study of influence, exerted by the road projects on road traffic safety was carried out on the basis of data, contained in the System of Registry of Accidents and Collisions (Polish acronym: SEWIK) for the years 2006-2012, and the questionnaire-based survey. The level of safety on the motorways and expressways, or, more broadly – on the separate traffic roads, is being assessed as much higher than on the remaining national roads. Construction of a motorway results in a significant drop in the number of persons harmed in the accidents over the connections between the cities considered. The fast traffic roads, including the ring roads, being the segments of expressways, significantly improve the safety over the routes of national roads, but do not entail any important change in the accident rates on other roads.

Abstract The analysis of the influence, exerted by the road projects on traffic intensity, was performed for the period 2000–2010 on the basis of data on the intensity of traffic of passenger cars and heavy good vehicles over the network of out-of-town national and provincial roads. An abrupt increase of the number of cars and the initiation of the intensive infrastructural undertakings contributed to an essential increase in the intensity of road traffic in Poland. Opening of a motorway or of an expressway entails a shift of a part of traffic, especially of a part of the transit traffic, from the parallel national roads over to the newly constructed road segments. A motorway has, in comparison with the parallel national road, an important competitive time-wise edge, but the situation gets complicated when a motorway fee is introduced. Local factors also exert a significant influence on the changes in traffic intensity.
