Reittejen

Reittejen is a term used in transport planning to denote the collective network of routes that connect nodes in a transportation system. The term is most often encountered in Finnish-language planning literature and is used to discuss how different routes interact to form a connected network, with attention to flow, redundancy, and accessibility rather than to any single segment.

In practice, reittejen encompasses routes across modes, including bus lines, tramways, cycling paths, and pedestrian corridors. It emphasizes network structure, transfer points, and the potential for modal interchange. The concept supports evaluating how well the network serves populations and destinations under varying demand.

Analytical methods for reittejen include graph-theory based network modeling, GIS mapping, and transport simulations. Common metrics are connectivity, route coverage, centrality, and redundancy, used to assess resilience and efficiency and to compare alternative configurations.

Applications of reittejen analysis include urban planning, transit operations, and emergency management. It helps planners evaluate improvements, expansion plans, and service changes for better accessibility, reduced travel times, and increased robustness against disruptions.

Challenges include data quality, dynamic demand, multi-modal integration, and scale. As a planning tool, it is often complemented by rider information, cost data, and policy objectives.
