In this paper the use of social media and web to collect data for travel surveys related to disruptions on public transport networks is discussed.
Public transport users are not mobility “static”; they use the web to get information on actual travel times, they check on the Smartphone the arrival of their bus, they even consult transport related websites to get information on potential disruptions on the network. Generations Y and Z are more technologically oriented compared to previous generations. The possibilities offered by social media are endless. On the other hand, bias and limitations of using social networks to conduct transport surveys need to be further examined.
In this paper the use of social media and web to collect data for transport surveys related to disruptions on public transport networks is discussed. The purpose of this paper is to analyze the factors that influence travel patterns during public transport strikes and their complex interactions with social media applications. The data used comes from a web-survey conducted in between 2011-2012, in Athens, Greece to assess travelers’ choice of mode in the event of transportation disruptions.
Among the variables tested are demographic and socio-economic variables, frequency of car use and PT use, car ownership status. The analysis focuses on identifying any relation between travel patterns, and demographic and socio-economic distribution in the responses through the various social media in the choice of mode during public transport disruptions. The motivation of this research came through the ongoing need for data collection for various travel surveys.
For this analysis statistical tests were performed and concluded in statistically significant parameters for various types of interruptions in Public Transport. Results identified biases on demographic and socio-demographic characteristics and ways to overcome these biases are proposed.
