St. Charles County, MO

St. Charles County, MO 8 largest cities – there are officially 15 cities and 2 villages within St. Charles County

Goals and Objectives Goals To reduce travel times, delays, fuel consumption, greenhouse gas emissions and incidents, and increase mobility and reliability of travel in St. Charles County Objectives Build a communication network to support a county-wide ATMS Procure and install ATMS software and hardware needed to manage all signals in the county from a centralized location Develop and optimize coordinated signal timing plans Supply and install supporting ITS devices such as pan tilt zoom (PTZ) cameras, DMS, count stations, and travel time sensors Monitor traffic during peak hours

Multi-Agency Partnering 8 largest cities – there are officially 15 cities and 2 villages within St. Charles County

Multi-Agency Partnering 2009 - Periodic Stakeholder Meetings 2011 - Monthly Stakeholder Meetings 2012 - Gateway Green Light Advisory Board Formed (MOU) 2015 - Technical Advisory Committees to the Board 2016 - Quarterly Performance Measure Reports, Citizen Surveys 2017 - Survey Results, Public Outreach

Project Overview Gateway Green Light - Phase I CMAQ 5414 (616), Controllers, Modems, ATMS Software, Master Plan $5.0 million Construction Completed, Ongoing Support Gateway Green Light - Phase II CMAQ 7302 (638), Network $3.8 million Essentially Complete Gateway Green Light - Phase III CMAQ 5414 (623), Network, Travel Time Detectors, PTZ Cameras, Count Stations, DMS $2.0 million Anticipate Completion Fall 2017 Gateway Green Light – Arterial Management Interface (AMI) Alternate Route Plans and AMI $250,000 Complete AMI - will fund the development and implementation of alternate route plans and an Arterial Management Interface for better and faster traffic incident management on GGL controlled arterials. This project would expand upon the MoDOT incident management plans and Arterial Management Interface already in place along the I-70 corridor through St. Charles County by incorporating the GGL controlled arterials. By incorporating the GGL controlled arterials, it allows greater flexibility and more options for diverting traffic during severe incidents on I-70 and other major roadways throughout St. Charles. A traffic incident management plan would be developed for use by the GGL Operator at MoDOT’s Traffic Management Center (TMC) that would allow for quick response time during severe incidents to keep traffic moving.

Project Overview Gateway Green Light - Phase IV CMAQ 5414 (632), Signal and ITS Upgrades, ATMS Enhancements, Feasibility Study Update $2.1 million Anticipate Completion Fall 2018 Gateway Green Light - Phase V CMAQ 5414(633), Signal and ITS Upgrades, ATMS Enhancements Anticipate Completion Fall 2019 Gateway Green Light - Phase VI CMAQ 6841A-19, Signal and ITS Upgrades, Emergency Vehicle Pre-Emption $2.4 million Anticipate Completion Fall 2020 Regional ITS Data Sharing (RIDSI) - Phase 1 CMAQ (in accordance with ITS Architecture) Partnership with MoDOT Regionwide ITS Data Sharing Initiative - Phase I In accordance with the St. Louis Regional ITS Architecture, MoDOT and St. Charles County are leading the effort to study, implement, and deploy this data sharing effort among other regional partners.  This first phase will lay the groundwork for identifying and implementing the technology and data standards whereby participating agencies contribute available traffic and incident information into a central data source. From that source, any agency or organization can acquire the information in a standardized format.   Partial implementation of data sharing and incident data exchange involving MoDOT and St. Charles County will be included in the project. Implementation in other parts of the region will be done in future phases. Phase I includes 3 components: Regional Transportation Communications Standardization Platform Regional Incident Data Exchange Transportation Archiving and Performance Assessment System

Evolution of Communication Design Deploy a mixed media Communications Network Fiber 125 miles existing 8.5 miles planned for Phases 4-6 Commercial Cellular 27 locations remaining Point-to-Point Radios or Leased Lines Use County Towers Open to all County / Government Agencies Federal Regulation delayed County design/deployment, therefore… Phase 1 deployment used leased TelComm for network backbone

Evolution of Communication Design Modern IP based Open Network Architecture – supports any brand of IP based Layer II or Layer III device IP Scheme will support 100,000 plus devices 1GB+ Layer III Backbone w/ Multiple Redundant Rings NTCIP Compliant Arch.

ATMS / ITS Management TransCore TransSuite software selected as GGL ATMS Same Platform as MoDOT Freeway Management System NTCIP based Supports multiple brands and types of controllers and other ITS & ATMS field devices

Project Status 340 Signals 90 Travel Time Detectors 45 CCTV 1 DMS (2 more later this year) 11 Radios 91 Video Detection Systems 4 GridSmart (Aldis) Devices Owned by 10 agencies MoDOT has over 20 additional DMS Video Detection are configured to count cars GridSmart has Count Capabilities – Both now feed count data to MS2 platform

Project Status MS2 – Count Module http://sccmo.ms2soft.com

Performance Measures 16% Reduction in Average Travel Time

Performance Measures Customer surveys will compare public perception versus measured performance Planning time index will be used which is a ratio of the worst travel time (95th percentile) compared to the free flow travel time

Customer Survey 71% Responded on signalized roadways when surveyed in 2016.

Special Events

Non-Recurring Congestion

Future Phases Data Sharing

Future Phases Emergency Vehicle Signal Priority Improves response times up to 25% Reduces the intersection crash rate CMAQ Funds secured for 2019
