Proposed Development of a KPIs Module for Traffic Modeling London, 13 April 2012 N. Eden Technion – Israel Institute of Technology

Outline  KPIs Recap  KPIs for Decision Making  Models & Tools AIRE  CONDUITS DST Aggregation Pollution KPI

KPI Sliced to Categories

Roles of KPI (Cities’ Requirements)  Assess benefits Cost vs. benefit of investment Assess the usefulness of ITS as a whole Identify the limits of ITS  Assist Decision Making  Contract Monitoring  Promote cities’ interests

Emissions Model Types  Average-speed mean travelling speed, VKT  Traffic-situation particular traffic situations (e.g. ‘stop-and-go’)  Traffic-variable traffic flow variables (e.g. average speed, traffic density, queue length, etc.) Validation of road vehicle and traffic emission models – A review and meta-analysis Smit et. Al, Atmospheric Environment, Volume 44, Issue 25, August 2010, Pages 2943–2953

High Resolution Emissions Model Types  Cycle-variable various driving cycle variables (e.g. idle time, average speed, positive kinetic energy)  Modal engine or vehicle operating o Similar data requirements as Cycle variable Validation of road vehicle and traffic emission models – A review and meta-analysis Smit et. Al, Atmospheric Environment, Volume 44, Issue 25, August 2010, Pages 2943–2953 VERSIT+ (EnviVer) PHEM, AIRE

AIRE (Analysis of Instantaneous Road Emissions)  Emission estimation from traffic micro- simulation models NO x PM’s Carbon  Transport Scotland SIAS TRL

AIRE (Analysis of Instantaneous Road Emissions)  Instantaneous Emissions Model (IEM) - PHEM P assenger car & H eavy duty E missions M odel o Technical University of Graz o High accuracy for fuel consumption, CO 2, NO x, PM

AIRE (Analysis of Instantaneous Road Emissions)  Emission estimation based on IEM tables reflecting range of engine types, loads, gradients, etc. Timestamp data o Vehicle type, Speed, Acceleration, Gradient
