  1. ICM San Antonio – IH-10 Corridor Brian Fariello, TxDOT

  2. Operational – Why San Antonio needs ICM • IH-10 primary corridor in San Antonio • Connects central business district with residential areas • Two main UTSA campuses • South Texas Medical Center • Major employment centers include USAA and Valero • Recreational attractions: Six Flags, shopping, River Walk, and the Alamo (Most visited tourist destination in Texas)

  3. Operational – Why San Antonio needs ICM • Need for ICM • Increased congestion and decreased reliability on expressway • Arterials are congested and lack single centralized signal control system to maximize throughput • Decreased bus transit reliability and spare capacity available • Future construction (BRT and expressway) will require improved transportation management

  4. Approximately 15 miles of IH-10 from suburbs to downtown Split level expressway located near down-town Parallel frontage roads Adjacent arterials run throughout corridor Fredericksburg Road Bandera Military / Blanco Bus transit services Significant ridership in corridor Express service Park and ride locations Operational - San Antonio ICM Corridor Overview

  5. Operational – How ICM will help San Antonio • ICM Operational Approaches and Strategies • Information sharing / distribution • Improve the operational efficiency of network junctions and interfaces • Accommodate / promote cross-network and modal shifts • Manage capacity and demand in the corridor • Specific examples: • Promoting alternative routes on DMS messages • Improving throughput on frontage roads and arterials with signal timing patterns to support diverted traffic from expressway • Improved traveler information services

  6. Operational – San Antonio ICMS Operational Tactics

  7. Institutional – Who are our ICM Stakeholders • Texas Department of Transportation • City of San Antonio • VIA Metropolitan Transit • San Antonio Police Department • Emergency Operations Center • San Antonio Fire Department • Southwest Research Institute • Texas Transportation Institute

  8. Institutional – How San Antonio defined Roles and achieved Buy-in among ICM Stakeholders • ICM mission and vision statements based on common transportation themes from public stakeholder agency’s mission statements, vision statements, and goals • Allows for executive level support from public stakeholder agencies • Utilized existing facilities, forums and working relationships to facilitate institutional cooperation • Existing San Antonio ITS Technical Committee • Establishes ICM policy and operational procedures • Provides ICM oversight • Manages fiscal and infrastructure planning for region • San Antonio TransGuide Facility • Currently hosts public sector agencies in co-located operations facility

  9. Technical – San Antonio ICMS System Architecture

  10. Technical – How San Antonio facilitates ICM • Existing Subsystems Key to ICMS • Center-to-Center (C2C) • Collects data transportation related data from disparate regional systems • Data “fused” into central server for distribution between agencies and systems • Standards based • Data Archive • Archives C2C data • Historical data available • Incident detection based on historical trends • Data Analysis

  11. Technical – Newly Proposed ICMS Subsystems • Center-to-Center Interfaces • ICMS Operations User Interface • Decision Support Subsystem • Historical Data Analysis • ICMS Event Management • ICMS Arterial Travel Times • Corridor Web Site • Personal Emergency Trip Planner • Corridor Data and Map • Mobile Device Accessible Web Site

  12. Lessons Learned – Operational • Operation co-location essential • Working group meetings • Ensures stakeholder involvement • Forum to obtain input and reach a consensus • Recommend three to five meetings • Involve stakeholders with • Operational knowledge • Decision making power • Could require more than one stakeholder per agency • Leverage existing operational strategies • Example: San Antonio Ice Plan

  13. Lessons Learned – Institutional • Leverage existing agency coordination and relationships • Utilize existing forums • San Antonio ITS Technical Committee • Understand public agency objectives and current issues • Communicate ICM in terms of other’s needs

  14. Lessons Learned – Technical • Requirements Specification • Focus requirements on “what” the system will do functionally • Avoid designing system details during requirements development • Utilize staff and consultants familiar with existing systems • Maximizes building upon existing systems and capabilities • Arterial travel times / conditions data “challenge” • Lack of ITS infrastructure for gathering this data exists nationwide • Potential to use bus AVL data scaled to account for service related stops and reduced travel speeds • Challenges exist in applying standard IDAS software results at a corridor level
