Sammanfattning
This thesis evaluates the efficacy of traffic management strategies at the Museirondellen and Södra
Strandgatan intersections in Jönköping, Sweden, emphasizing bus prioritization and geometric
design modifications. Due to their significant traffic volumes and complex designs, these
intersections pose key challenges in terms of congestion and safety. Advanced traffic simulation
tools are employed to assess current conditions and to explore the impacts of proposed geometric
changes under various traffic scenarios, including increases of 10%, 15%, and 20% in traffic
volumes. The study incorporates a survey of local drivers to gather firsthand insights into the
current traffic issues and perceptions of the proposed changes, complemented by detailed
geographical data and signal timing information from local databases. A new intersection design
was proposed and tested through simulations, demonstrating its potential to alleviate congestion
and enhance public transport efficiency. The research aims to analyze existing traffic inefficiencies,
evaluate the effectiveness of bus prioritization, and assess the new geometric design's impact on
traffic flow and safety. The findings are intended to provide evidence-based recommendations that
could influence urban planning and policy-making in Jönköping and other cities with similar
challenges. The significance of this study extends to its approach to integrating bus traffic within
urban intersections and optimizing intersection geometries to foster sustainable traffic systems.
Expected outcomes include improved urban mobility, enhanced road safety, and actionable insights
for future enhancements in traffic management in urban settings.
