Avivim TA’s Mobility management system

Urban Mobility Management Concept Transportation objectives often conflict  Accessibility Vs. Mobility  Efficiency Vs. policy The system is composed of humans rather then packets  Un-expected behavior  Changes over time  Stochastic in nature

Urban Mobility Management Concept The management system supports the engineer  Presents relevant information  Provides recommendations for appropriate actions  Sub-Network most suitable signal program  Supports data analysis processes  Historical data charts  Pattern identification

Urban Mobility Management Process Strategic Management Level Defining traffic management overall long-term goals Tactical Management Level Development and implementation of medium-term traffic- management principles needed to achieve long-term goals Operative Management Level Implementation of real-time traffic-management actions based on medium-term principles Central Control Transmission of operational instructions and analysis of operational data collected from input/output devices Field Control Implementation of operational instruction and collection of operational data from input/output devices Performance data Operational instruction Management Layer Operational Layer
