## 1 Introduction  
In the city of Valparaiso, there has been growing interest in improving the quality of public transportation to promote sustainable mobility and reduce the reliance on private cars. In this context, both the trolleybus system and the EFE metro are key components of the city's public transport network [1, 2]. However, despite the existence of these public transport systems, the quality of pedestrian accessibility plays a crucial role in users' experience and their decision to not only reach but also use it [3]. If pedestrian accessibility is deficient in terms of safety, comfort, or efficiency, users are likely to opt for other forms of transport, such as private cars, which increases traffic congestion and environmental problems [4]. Specifically, regarding the connection between the trolleybus system and the EFE metro in Valparaiso, there are questions about the condition of the pedestrian access points that link them. It is unclear whether these access points meet the necessary standardsto provide a satisfactory experience for users and promote intermodality between the transportation systems, considering sidewalks and crossings (see Figure 1). Therefore, an evaluation of pedestrian access points is needed to identify potential deficiencies and propose appropriate accessibility solutions. The evaluation of pedestrian access points between the trolleybus system and the EFE metro in Valparaiso is crucial for several reasons:  
* Improvement of the user experience: Pedestrian access points are the first contact users have with the public transportation system. If these access points are deficient in terms of safety, comfort, or accessibility, a negative experience is created for users, which could discourage them from using public transport. * Promotion of intermodality: Efficient connection between different modes of public transport, such as trolleybuses and the metro, is essential for promoting intermodality and facilitating user movement. Evaluating pedestrian access points will help identify possible barriers to intermodality and propose solutions to improve it. * Impact on urban mobility: An efficient and attractive public transportation system is fundamental for reducing the reliance on private cars and promoting more sustainable mobility in the city. By evaluating and improving pedestrian access points, a more user-friendly environment can be created for public transport users, which could increase usage and decrease vehicular traffic. * Optimization of efficiency: Efficient and well-designed pedestrian access points help to streamline the movement of users between the trolleybus system and the EFE metro. A thorough evaluation will identify potential bottlenecks, congestion, lack of flow in pedestrian routes, and long waiting times. By addressing these aspects, greater efficiency in movements can be achieved, reducing travel times and improving the user experience. In summary, the evaluation of pedestrian accessibility through access points between the trolleybus system and the EFE metro in Valparaiso is essential to ensure safety, effi

Addressing these aspects creates a favorable environment for public transport use and promotes more sustainable mobility in the city, which is the aim of this study. The specific objectives are (a) to identify the study area and pedestrian accessibility elements to evaluate, through manuals, regulations, and site visits; (b) to design a pedestrian accessibility evaluation system that is descriptive and numerical, based on the identified elements; (c) to evaluate the pedestrian access points between the trolleybus service and EFE metro in Valparaiso in the study area using a descriptive and numerical methodology. The paper is structured as follows.
