Exploring Passengers’ Travel Behaviors Based on Elaboration Likelihood Model under the Impact of Intelligent Bus Information

Abstract

The ubiquitous intelligent transportation infrastructure in metropolitan cities has enabled bus passengers to access comprehensive (even real-time) bus information. However, the impact of different types of information on passenger behavior is still insufficiently understood. Combining with the theory of information processing path, this study partially fills this gap by adopting an elaboration likelihood model (ELM) suitable for explaining how the various types of intelligent bus information influence passengers’ choice behavior. Six types of intelligent bus information (information of bus lines, estimated travel time, estimated time of arrival, congestion inside bus, road congestion, and bus fare) are used as six independent variables, and passengers’ departure time, travel routes, and travel modes as dependent variables. Valid questionnaire assessments were collected from 285 participants at 4 bus stops equipped with intelligent bus system in Harbin, providing quantitative data to verify each hypothesis. The results show that six types of intelligent bus information to different degrees (significant influence, slight influence, and no significant influence) affect three types of passengers’ choice behaviors; the information of estimated travel time and that of road congestion are both significantly effective in all three types of choice behavior while bus fare has no significant influence. Meanwhile, other types of information have a significant or slight effect on certain behavior. The results of this study can be used to design more reasonable intelligent bus information provision strategies to meet passengers’ requirements.

Effective Communication for Water Resilient Communities: A Conceptual Framework

“…ELM was developed by Petty and Cacioppo in the 1980s [50,127]. ELM has been used in various disciplines such as health [128], tourism [129], transport [130], products [51] and water conservation campaigns [31]. ELM proposes that message receivers can be persuaded in one of two ways: a central route to persuasion or a peripheral route to persuasion.…”

Study on the Route-Selection Behavior of Bus Passengers Based on an Evolutionary Game under the Condition of Information Guidance

“…From the perspective of travelers, Fonzone et al [2] analyzed the characteristics of passengers' bus choice behavior under RTI based on revealed-preference and statedpreference survey data. Wu et al [3] refined intelligent bus information into bus route information, estimated arrival time information, in-vehicle congestion information, total travel information, and fare information; the researchers then analyzed the impact of the above information on passenger travel paths. These studies have shown that bus itinerary information and in-vehicle congestion information have a significant impact on passengers' travel route choices.…”

Travel Time Behavior Study of Malang-Denpasar Intercity Bus Considering Sailing Time of Ketapang-Gilimanuk

“…Thus, of course, travel time will be a factor for potential passengers to consider. [1], [2], [3], [4] The behavior of prospective passengers will also determine the preferred mode of public transportation and the choice of mode types. This is in accordance with the results of research conducted by Han et al 2014) also emphasized the behavior of choosing the mode of travel between buses and non-buses.…”
