This study advocates for promoting public transportation to alleviate traffic congestion and emissions in city centers. It introduces a zoning plan with designated parking at four points around each zone. Those using public transport from farther parking spots would get discounts at city center shops, and the parking ticket would grant access to city services. This aims to reduce congestion, pollution, and enhance public transport efficiency. The proposed model focuses on implementing this strategy in the greater area of Thessaloniki, dividing the city into three zones. Each zone will offer varying discounts of 5% (Zone 1), 10% (Zone 2), and 15% (Zone 3), with the highest discount reserved for Zone 3, situated farthest from the city center. To validate the effectiveness of our approach, the future plan is to construct a detailed model and conduct a comprehensive survey of stakeholders. The insights gained from the survey will contribute valuable data to support the efficacy of the proposed zoning strategy. By implementing this innovative solution, a positive impact on the overall urban environment is anticipated, with reduced traffic congestion, lower pollution levels, and improved public transportation utilization.
