Travel behavior refers to the patterns and decisions individuals make regarding their travel activities. It encompasses various aspects such as the choice of transportation mode, route selection, travel time, and frequency of trips. Understanding how travel behavior works is crucial for urban planners and policymakers as it helps in designing efficient transportation systems and promoting sustainable travel practices. 

For instance, by identifying what components of urban form influence different travel behavior, urban planners and policy-makers can further certain agendas. If they saw a strong relationship between availability of pedestrian-friendly infrastructure and people choosing walking over vehicles, they may actively incorporate such infrastructure in the design. This way, cities will be effectively planned to promote sustainable travel behaviors.

With advancement in technologies in the past decade, data collection methodologies in travel behaviors have shifted to more modern methodologies. One such modern methodology is using data recorded by GPS devices. GPS devices play a significant role in analyzing travel behaviors by providing accurate and detailed data on individuals’ movements. These devices record the time and location of each trip, allowing researchers to study travel patterns and behaviors more precisely. For instance, GPS data can reveal the most frequently used routes, peak travel times, and areas with high congestion. This information is invaluable for urban planning, as it helps in identifying bottlenecks and optimizing traffic flow.

This blog explores how travel behaviors can be analyzed using data collected from GPS devices.

Importance of Quality Data

To have results that you can successfully use, you need to collect quality data. Otherwise, the results are not reliable and could not be effectively used for policy and planning.  Therefore, it is extremely important to always try and improve the quality of research. Quality is a critical component in obtaining accurate and useful information.

Comparing Traditional Data Collection Methods with GPS-Based Methods

Before more advanced technologies entered the picture, traditional travel surveys have been the predominant source of data on travel behaviors. This method, however, had its limitations. Firstly, it depended on participants’ commitment and secondly, on participants’ memory. Naturally sometimes participants would fail to respond accurately or forget details. This caused data to be unreliable.

In contrast to traditional surveys, GPS-enabled devices, such as smartphones, are more accurate and meticulous. These devices consistently track movement, providing frequent and precise travel details.

GPS-based methods are able to collect spatiotemporal data. It means they include both time and location details. With spatiotemporal data, you can see where people went, along with the path they took and the time they spent in each location. This type of data is extremely helpful in decoding complicated travel behaviors and patterns.Looking to enhance your own tracking capabilities? Choose Imperial GPS devices!

Integrating GPS Data with Modern Technologies

Integrating GPS data with modern technologies like machine learning and stochastic models is a promising prospect. The way machine learning algorithms could process large data sets for patterns and trends is unmatched. Traditional statistical methods cannot compete. This combined with stochastic models, can help identify nuances in travel behaviors. This is because stochastic models are specifically designed to handle randomness and predictability in data sets. 

However, this integration of technologies is still in the early stages of development. For this integration to work effectively, it requires reliable ground truth data. This means, accurate data that can be used to validate the models and algorithms is required. This is a huge challenge because if the data is inaccurate, then the conclusions made by these technologies may be less accurate and even deceptive. 

The Potential of Smartphone GPS Data

Smartphones are great instruments for good-quality spatiotemporal data collection. They have in-built GPS which can record data consistently, without requiring any active input from users. In contrast to traditional surveys, collecting data from smartphones is cheaper and does not put extra responsibility on the participants. In addition to this, because of the widespread use of smartphones, data is gathered from a large and diverse sample. This improves the representativeness of the findings.

There is, however, a critical gap. Raw GPS data, produced by GPS devices, is not being fully utilized. Researchers are not studying the raw data itself or the methodologies which are being employed to analyze this data. Covering these components could further improve data accuracy and conclusions of studies.

Future Directions for Research

GPS data produced by smartphones is superior over traditional travel survey data collection. Smartphone data offers higher accuracy and minimizes participant responsibility. With smartphone data, travel behavior research will be more reliable and yet, cheaper to carry out.

Having said that, there is a need for deeper assessment of raw GPS data. Only by deeply studying the raw data, would researchers be fully utilizing the potential of this data. There may be valuable trends or insights that are being overlooked due to a lack of deep study. To do so, researchers should develop methodologies to study raw GPS data effectively.

Similarly, to understand the complete picture of travel behaviors, GPS data needs to be studied with other types of data. For example, social media data. However, studying two data sets together is complex and may present relationships between variables which aren’t conspicuous. To derive sophisticated insights, researchers should utilize the latest developments in technology and employ it to analyze GPS data. Machine learning and other such technologies hold promise of generating more meticulous and accurate insights into individuals’ travel behaviors.

Conclusion

Travel behaviors is an important area of research that has benefited significantly from the emergence of GPS technology. In-built GPS in smartphones have made data collection efficient. Before this, data was predominantly collected through travel surveys. Travel surveys placed a lot of responsibility and reliance on individuals’ participation and answers. As opposed to this, GPS technology does not require individuals to actively log data. Furthermore, the quantity and quality of data that can be obtained from smartphone GPS is extremely superior to traditional data collection methods.

There is, however, room for advancements in how we analyze the data received through GPS devices. By developing better methodologies and incorporating more technologies, researchers could further boost accuracy and comprehensiveness of their findings on travel behaviors.
