Testing the quality of underground transport in Bucharest

Open access


In a city with overcrowded traffic, a component of the common transport is Bucharest transportation of metro (subway passenger transport on the railway network underground and surface) and is the core activity of METROREX S.A. The company aims each year a greater number of passengers according to the charts of the movement of subway trains to ensure adequate transport capacity as required and optimal conditions of comfort and safety. Each year, the company aims to find out the opinion of passengers on the transport conditions and, in this respect, organize a survey with the aim of testing the quality of underground transport in Bucharest in 16 subway stations considered to be representative. In this paper I intend to do an analysis using statistical research methods, of the quality of underground transport in Bucharest, using data from the survey conducted in the year 2014. Data collection in the stations was realized through 32 operators, by 2 in each station (one in each direction of travel) by completing questionnaires (using interview technique or face to face technique), using a sample considered representative of 2,400 travelers with a margin of error of ± 2% on a 95% probability level. Data collection was made during the period when passenger traffic is large enough to provide a good representation of data and cover the entire program running underground. The questionnaire contains eight questions that have allowed those who responded to the survey to fit in the time between trains in circulation. In 2016, the structure of the questionnaire was modified, questions were modified for a more effective assessment of characteristics of observation. The answers to the questions contained in the questionnaire were collected by operators in the 16 subway stations: Piața Unirii 1 and 2, Piața Victoriei 1 and 2, Dristor 2, Nicolae Grigorescu, Universitate, Piața Sudului, Pipera, Eroilor, Gara de Nord 1, Obor, Crângași, Pantelimon, Parc Bazilescu and 1 December 1918, analyzed and processed based on 2400 questionnaires. A new category of polls states in the present and is determined by evolutions in computer networks and communication, are called online surveys conducted on the Web. Also in this paper, I propose the implementation of a solution based on an online survey website that includes the online version of the questionnaire used to collect data from the virtual environment.
