metaYLE — Ülemiste Mobility Nudge

Ülemiste — home to Tallinn Airport, the future Rail Baltica terminal, and the Ülemiste City business district — is expected to roughly double in size as high-speed rail arrives. Before approving further development, the city needed to know: at what point does current road and transit capacity actually run out, and what happens if we invest in the wrong things?

Won through public procurement, jointly financed by the City of Tallinn, Tallinn Airport, and district developer Mainor Ülemiste. Delivered with partners Ramboll Finland and Raul Kalvo/Inphysica, running from a 2019 bid through final delivery in 2021.

Combined a roughly 800-respondent employee survey on commuting behaviour with traffic counts, tram occupancy data, and mobile positioning data, modelled through agent-based simulation (GAMA) and GIS accessibility analysis. Five growth scenarios were tested — from road-expansion-led to active-mobility-and-transit-priority — each projected forward across multiple development stages.

Delivered as a full Estonian report with English executive summary, technical annexes, and a final presentation, alongside a “star plan” spatial concept for five development corridors radiating from Ülemiste.
