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
