Many people now rely on social media for news and other important information. Technological advances in cell phones and other mobile devices have given the general public far greater access to current events through multiple sources such as Twitter, Facebook, YouTube, Flickr and other online resources. One major advantage of this new technology is that it “pushes” content directly to users without them have to search the internet for themselves. It also lets providers share information at any time and to quickly correct any erroneous postings.

Transit agencies can take advantage of this to communicate directly with their customers, particularly in emergency situations. Under normal conditions, mobile apps can help with travel planning, listing arrival and departure times, delays, and alternate routes, even before a traveler reaches a station where electronic message boards may be located. Such remote communications can also be useful in alerting transit users to service problems as well as planned or unexpected changes or disruptions in service.[1]

A study of 86 international transit providers found Twitter to be the most commonly used form of social media, at 86%, followed by Facebook, at 33%.[2]

One advantage of social media is that is can reach a wide audience by making information available to others, including traditional media outlets, that can rebroadcast critical information. A big plus for transit agencies is the fact that millennials (those born between 1980 and 2000) who are increasingly using public transit are also heavy users of social media.[1] Another cited advantage of social media was the two-way nature of communication allowing agencies to respond to consumer questions and to send and obtain real-time information about conditions on the system, as well as customer opinions. This may require additional staff resources to monitor and timely respond to messages or risk consumer dissatisfaction, but this information may also be quite useful though in future agency planning which could save staff time in the long run.[2]

Emergency Response

A recent study following Hurricane Sandy in New York found that social media had advantages to transit providers over traditional media. For instance, pictures could be transmitted showing the condition of stations and facilities that support decisions to reduce or shut down service. Local agencies, including the MTA, NJT and PATH all increased their tweets during the emergency. Some used the service to answer questions and collect information directly from users. They also provided real time information on station closings and re-openings following the storm.[1] The study’s authors suggest that transit agencies begin adopting policies regarding their use of social media including when the need to post important information quickly may outweigh accuracy or completeness.

  Agency credibility may depend on the accuracy and timeliness of the information provided to consumers. Due to rising expectations among users of social media, many will expect to be provided with information about incidents as soon as they occur. Failure to keep “ahead of the pack” as one transit provider put it could hurt an agency’s image with the public. But this may require a substantial commitment of agency staff resources and other support. Social media can be particularly useful for high-frequency transit modes where operators may need to communicate with a large number of commuters in a short amount of time, to for instance, advise them of travel delays or unplanned route changes. However, the agency must also weigh the desire to keep the public informed with the need to provide accurate information. One agency concern noted by researchers was that information may remain on sites like Facebook that is inaccurate or has become outdated and that such information can also be rebroadcast over services like Twitter. As such, some agencies reported using such sites only for notifying users that the operator is aware at situation exists and that they should consult agency websites for more detailed and up to date messages. One advantage of social media was the ability to reach passengers who are not yet on the system, who may still be able to change plans and take alternative transportation, particularly around rush hours, thus cutting down on the need to provide alternatives such as replacement buses in cases where such services are provided. As one agency put it, social media allowed them to “’evaporate’ its market.” (p. 123)

  Social media can also be used in long range transit planning. Traditional methods of public involvement in planning and environmental review processes may not be able to reach a large number of people due to the time and inconvenience some interested parties may face in attending public hearings. Social media offers the opportunity to create conversations outside of a physical space as well as engaging a wider number of people. It can be used to disseminate information through pictures, charts, narrated videos, and other innovative means to describe the project and the planning and environmental review process. Public reaction can be gathered through on line polls, posted comments, and blog postings. The Metropolitan Transportation Authority in Los Angeles made used Facebook, Twitter, and YouTube to engage the public in its Westside Subway Expansion project. This and other cases studies are reviewed in a recent TRB report. There are however, some possible barriers to using social media, including that some individuals may not have access to it or may use it infrequently due to factors such as age, income, or lack of education. In addition, some persons’ use may be limited the result of a physical disability. Some ethnic groups may be more or less likely to use different types of social media. Agencies considering using social media to complement more traditional approaches should consider how best to overcome some of these limitations, including consulting with local community leaders regarding preferred methods of communication .

Public Involvement in Planning

To date there has been limited research on how to measure the effectiveness of social media communications as a tool of public involvement and some confusion how to document and respond to information collected through social media as part of environmental review. It can be useful in disseminating information to a large segment of the public particularly through rebroadcasting information by recipients ("retweets" or "RT").

A study of the experimental use of social media as part of the City of Austin's Strategic Mobility Plan looked at its effectiveness in involving citizens in the planning process, providing citizens with a voice in decision making, promoting a sense of community among those interested in transportation. Careful analysis found that information from microblogs could be aggregated in a meaningful way for planners but that future research would be needed to streamline the process.

Studies have shown that social media users tend to be diverse but there are issues whether they are representative of the general public.

Those considering use of social media in planning should "engage public officials and other key stakeholders early in the public involvement planning process."

This study of Saint Louis, Missouri, Metro riders examined how their use of communication technology use affected their transit use and rider experience. In adddition, it identified specific demographic groups that would benefit from supplemental technology methods more conducive to their particular information needs. Those using smartphones or text messaging reported significantly higher levels of satisfaction with service, while those (including riders older than 40 years of age) who were less likely to own smartphones might be better served through websites and interactive voice response services. It concludes with a call for RTI application development that mirrors the unique characteristics of transit ridership.

Multiroute corridors are a common feature of bus networks. In these corridors, passengers select a route from a set of parallel routes that serve the desired destinations. Understanding how passengers make these decisions can help measure passenger experience and inform network and service planning. This paper reports on a web-based survey used to collect information on users of a multiroute bus corridor in London both as a tool to understand behavior and as a demonstration case for the viability of web-based surveys, a relatively new methodology for data collection on public transport user behavior. The authors find that online surveys can collect detailed information from a large, fairly representative sample of bus passengers and that route choices depended on several factors.
