Cost-benefit analysis on composite traffic in the Helsinki Metropolitan area estimates the health and other impacts of composite traffic, a hypothetical large-scale demand-responsive public transportation system that is managed using 4-8-seat vehicles. The model for this assessment is Composite traffic.ANA (run on Analytica).

Scope

Purpose

The purpose is to estimate the impacts of composite traffic compared with private cars. The assessment is based on a previously published study, which is extended in this assessment to include also current public transportation (metro, buses, trams).

Boundaries

• Location: Helsinki Metropolitan area (ca. 1 million inhabitants).
• Time: Five years in the future (no major changes in infrastructure, but enough time to have a major change in transport habits).
• Time resolution: The impacts are assessed during one working day (24 h), with ca. 12 min time resolution.
• All motorized trips within the area are included; trips to or from outside the area are excluded, as well as walking and cycling trips.

Intended users

• Decision-makers in the Helsinki Metropolitan area
• Citizens in the Helsinki Metropolitan area
• Non-governmental organisations interested in promoting less-energy-intensive transportation modes
• Companies working on logistics or mobile services for citizens.

Participants

• Researchers in KTL
• Researchers in HUT?
• Researchers in Garnegie-Mellon West University?
• Anyone interested
