Abstract

In this study, we detected which means of transportation is beneficial from a travel time perspective in specific districts of Warsaw, Poland. To achieve this goal, we proposed a framework to perform a spatial analysis to describe the as-is situation in the city (the state that the situation is in at the present time). The framework contains the following elements: attractiveness analysis, travel time and speed analysis, and potential accessibility analysis. The relationship between the averaged nominal travel speed and the number of residents was also investigated. We used data from a journey planner, as well as land use and population statistics, and employed descriptive analytics. The results are presented as maps of travel times, travel speed, and potential accessibility, as well as scatter plots of dependencies between travel speed and number of residents. Unfortunately, public transportation ranks behind car and bike transport in terms of travel time, speed, and potential accessibility. The largest positive influence on effectiveness of traveling by public transportation is the metro and railway system; also, bikes can perfectly complement the public transportation system. The obtained results can be used to indicate directions of changes in the transportation system of Warsaw.

Highlights

Due to the increasing number of residents in cities, local authorities are trying to provide effective and efficient public transportation [1] in order to reduce the number of private cars in cities and to facilitate the functioning of residents, minimizing problems related to city transport [2]
Ai = Miexp(−βcii) + CVCj exp −βcij i=1 where Ai is the accessibility of the ith primary field, Mi is the number of residents in the ith primary field, CVCj is the coefficient of the destination attractiveness of the jth primary field, cii is the time of an internal trip within the ith primary field, cij is the travel time between i and j primary fields, and β is the sensitivity of the network user to the increase in physical, temporal or economic travel distance
More people live on the west side of the river and most people live in the central part of the city

Summary

Introduction

Due to the increasing number of residents in cities, local authorities are trying to provide effective and efficient public transportation [1] in order to reduce the number of private cars in cities and to facilitate the functioning of residents, minimizing problems related to city transport [2]. Recognizing and understanding the reasons why a passenger often chooses a private car in such situations instead of buses or trams is one of the key issues for improving the functioning of public transport Such issues are factors in accessibility analysis, which has many different definitions in the literature. The results of the analysis determine the places in the city where it is not profitable to use public transport because transport by private car is usually faster On this basis, it is possible to demonstrate where modifying an existing or adding a new city bus/tram line is needed to improve access to places inhabited by many potential passengers. It covers the following topics, each of which is described in several layers: the water network, the communication network, the land utilities network, land cover, buildings, structures and equipment, land use complexes, protected areas, territorial division units, and other objects
