Public transportation in Tenerife, particularly the guagua service—local terminology for buses—plays a crucial role in the mobility of both residents and tourists. The quality of service directly impacts user perception and daily transportation experiences. This analysis, based on user reviews collected from Google Maps between 2013 and 2024, focuses on identifying key areas for improvement to optimize Tenerife’s transportation system.
The main challenge is to transform criticisms into opportunities, with the goal of offering an exemplary public transport system that meets the island’s current needs.
Data Source and Methodology
The analysis was conducted by processing 2,299 user reviews related to bus stops in Tenerife. These reviews were gathered through web scraping of comments published on Google Maps. Advanced Natural Language Processing (NLP) techniques were then applied to classify the reviews based on sentiment (positive, negative, or neutral) and to extract key emotions, such as frustration or satisfaction. Algorithms such as TF-IDF were used to identify relevant terms, while the Latent Dirichlet Allocation (LDA) model helped group comments into specific topics.

Topic Intelligence
The analysis identified main topics and subtopics that reflect the key concerns of users:
- Transport Times: Punctuality and bus frequency are major concerns, with numerous reviews highlighting long waiting times and inaccurate schedules.
- Bus Stops: Users emphasize the need to improve stop infrastructure, requesting more seating and shelters for weather protection.
- Attractions and Beach Access: Many comments appreciate the ease of access to tourist attractions, highlighting the convenience of bus connections to beaches and other destinations.
- Drivers and Service Quality: The friendliness and professionalism of drivers are frequently mentioned as positive aspects of the service.
Identified Opportunities
The analysis also revealed critical areas requiring immediate improvements. Transport times and bus stop infrastructure generate the most dissatisfaction among users. Comments like "waiting too long" or "stops without seats or shelters" highlight the urgent need for interventions to enhance the public transport experience.
Although most users praise the quality of service provided by the drivers, some express dissatisfaction with punctuality or inappropriate behavior in certain cases.

Sentiments and Emotions
Overall, sentiments towards the guagua service in Tenerife are mostly positive, with 70% of reviews reflecting satisfaction. However, negative sentiments are concentrated around transport times and bus stop infrastructure, with 79% of negative reviews criticizing bus punctuality.
Frustration is the predominant emotion in reviews addressing low frequency and long waiting times.
Conclusion and Recommendations
The review analysis highlights that while the overall perception of the bus service is positive, critical areas require urgent attention to improve the user experience. Based on these findings, the following recommendations can help transform the service:
- Bus Stop Infrastructure Improvements: Add more seating and shelters to protect users from the weather, along with better signage and stop information.
- Schedule and Frequency Optimization: Adjust schedules and increase bus frequency on high-demand routes and during peak hours to reduce waiting times.
- Ongoing Staff Training: Ensure that drivers maintain high standards of friendliness and professionalism, enhancing the passenger experience.
- Transparent and Efficient Communication: Implement better communication systems to keep users informed about schedule changes and potential service disruptions.
