Planning trips is a cognitively intensive task involving conflicting user preferences, dynamic external information, and multi-step temporal-spatial optimization. Traditional platforms often fall short - they provide static results, lack contextual adaptation, and fail to support real-time interaction or intent refinement. Our approach, Vaiage, addresses these challenges through a graph-structured multi-agent framework built around large language models (LLMs) that serve as both goal-conditioned recommenders and sequential planners. LLMs infer user intent, suggest personalized destinations and activities, and synthesize itineraries that align with contextual constraints such as budget, timing, group size, and weather. Through natural language interaction, structured tool use, and map-based feedback loops, Vaiage enables adaptive, explainable, and end-to-end travel planning grounded in both symbolic reasoning and conversational understanding. To evaluate Vaiage, we conducted human-in-the-loop experiments using rubric-based GPT-4 assessments and qualitative feedback. The full system achieved an average score of 8.5 out of 10, outperforming the no-strategy (7.2) and no-external-API (6.8) variants, particularly in feasibility. Qualitative analysis indicated that agent coordination - especially the Strategy and Information Agents - significantly improved itinerary quality by optimizing time use and integrating real-time context. These results demonstrate the effectiveness of combining LLM reasoning with symbolic agent coordination in open-ended, real-world planning tasks.

Since our founding, Waymo has partnered with and listened to advocates for people with disabilities. As we continually improve our technology, we will strive to put individual passengers – with their diverse needs and experiences – at the center of our product to co-create the Waymo One ride-hailing service together. Today, we're launching the Waymo Accessibility Network to formalize and scale our longstanding collaboration with disability advocates. This will expand inclusion of their crucial voices and valuable perspectives as we work together to shape the future of transportation. The Waymo Accessibility Network brings together disability advocates who share in the mission of improving access, mobility and safety in our communities.

See below for contact information.] Many innovative technologies have taken the world by storm, and one of the most exciting ones is artificial intelligence (AI). The adoption of AI is no longer a futuristic concept, and this technology is powering many tech solutions that we use on a regular basis. Without even realizing it, we've become dependent on these solutions that were created to make our lives easier. The growth of AI will continue to accelerate in the future.

IBM announced the development of a new solution designed to transform driving in cities. Announced the day after SEAT presented its concept car Minimó promising to revolutionize urban mobility, 'Mobility Advisor' uses IBM Watson AI to help urban citizens make informed decisions about their daily transportation options including cars, scooters, bikes and public transport. With its advanced cloud and AI technologies, IBM is helping us to innovate new approaches to mobility that will transform our business strategy while improving the lives of people living in urban areas. Currently under development and designed to run as a mobile app on 4G/5G networks, 'Mobility Advisor' uses IBM Watson Assistant to provide users with a conversational interface to plan and optimise routes and suggest the most suitable transportation options. With IBM Watson Machine Learning, 'Mobility Advisor' can learn a user's preferences and make personalized recommendations for how best to complete a journey. It incorporates the user's appointments and historical data about previous choices in order to suggest the best modes of transportation each time – even if that means leaving the car behind, walking, or using one of SEAT's e-Kick scooters for the part of the journey.

MWC Barcelona is delighting attendees with many great exciting announcements in the Artificial Intelligence (AI) space. Headquartered in Martorell, Barcelona, SEAT is a member of the Volkswagen Group and one of Europe's biggest car manufacturers. Along with IBM, SEAT announced today the development of a new solution designed to transform driving in smart cities. SEAT is the only company that designs, develops, manufactures, and markets automobiles in Spain. Recently at MWC Barcelona, SEAT also presented its concept car Minimó promising to revolutionize urban mobility. Using IBM Watson AI, Mobility Advisor can help urban citizens make more informed decisions about their daily transportation options including cars, scooters, bikes, and public transport.
