  1. Cobb County Comprehensive Transportation Plan (CTP) Board of Commissioners Briefing January 22, 2008

  2. Purpose of CTP • Identifies multimodal transportation needs countywide • Recommendations include roadway, freight, transit, bicycle and pedestrian solutions • Compares needs against funding assumptions to develop strategic vision for implementation • Serves as a transportation planning “platform” upon which future detailed project concept development efforts will build

  3. Study Background • 2-year effort • Interjurisdictional, including Cobb’s unincorporated areas and 6 municipalities • Analysis reported for 4 Planning Areas encompassing entire county • 2 primary study parts: Transportation elements of DCA Comprehensive Plans and enhanced countywide multimodal recommendations

  4. Coordination and Outreach • Project Management Team (PMT) • Representatives from County, cities, ARC and GDOT • 12 meetings over the course of the study • Stakeholder Coordinating Committee (SCC) • Representatives from public agencies and private organizations • Appointed by each County Commissioner and municipality • 7 meetings (3/06, 6/06, 9/06, 1/07, 5/07, 8/07, 10/07) • Cobb Paulding Working Group (CPWG) • Specific focus on traffic within western Cobb and Paulding County impact • Representatives selected by Cobb County, Paulding County and the City of Marietta • 6 meetings (10/06, 1/07, 5/07, 8/07, 10/07, 12/07) • Special briefings conducted for municipalities and CIDs as requested throughout study duration

  5. Public Involvement • Public involvement meetings • 5 rounds (4/06, 8/06, 2/07, 10-11/07, 1/08) • 628 attendees from first 4 rounds • Study website (www.cobbdot.org/ctp) • Newsletters (4) • Fact sheets, press releases and meeting flyers • Stakeholder interviews (52 community leaders) • Surveys (1000 random phone interviews) • Contact database (600)

  6. Technical Process • Accepted methodologies and analyses used to ensure compatibility with regional planning processes • Regional model adapted to provide greater Cobb specific detail on travel patterns and volumes • Cost estimates and funding assumptions based on local, regional and state sources and tools

  7. Recommendations • Multimodal Projects • Roadway • Transit • Multi use trails • Pedestrian facilities • Policies and Procedures • Roadway • Access management • Freight truck routes • Travel demand management (TDM) • Bicycle, pedestrian and multi use trail facilities

  8. Factors Considered in Project Selection • Congestion • Overcapacity • Daily Delay • Travel Time Index (TTI) • Safety • Thoroughfare Plan Classification • Capital/Operating Costs per Rider • Potential Community and Economic Impacts

  9. Roadway Improvements • 137 total • Widenings = 50 • New roadways, extensions/connectors = 9 • Operational (access management, shoulder widening, corridor improvements) = 30 • Major intersection improvements (grade separation, realignment, new interchange) = 28 • Operational intersection improvements = 36 *Some projects include two types of improvements (e.g., widening and major intersection improvements)

  10. Transit Improvements • 17 total • US 41 high capacity transit (feasibility study) • Express bus service = 5 • Limited stop bus service = 5 • Local bus service = 3 • Circulator shuttle service = 3

  11. Trail & Pedestrian Improvements • Multi use trails = 44 total (~168 linear miles) • Pedestrian facilities = 80 total (~ 41 linear miles) • Safety & key corridor = 34 • LCI connectivity = 11 • School/activity center buffer = 35 • Assume roadway improvements will incorporate bicycle/pedestrian facilities and trail connections as appropriate

  12. Recommendations by Planning Area *Some projects are included in more than one Planning Area

  13. System Performance Results

  14. Access Management Policies • Continued adherence to development standards • Formation of access review committee • Completion of corridor specific access management plans, beginning with arterials • Required access management plan as part of concept development process for arterial and major collector widenings and upgrades • Access Management Overlay Districts (AMODs) • Appropriate access management applications based upon functional classification typology

  15. Truck Freight Policies • Land use compatibility • Operations and design • Maintenance • Intermodal facilities

  16. Travel Demand Management Policies • TMA expansion and development • Required TDM plans for new large land developments • CIDs critical to TDM implementation

  17. Bicycle, Pedestrian & Trail Policies • Strategically target investments to most suitable areas • Require roadway projects to include pedestrian and bicycle facilities as appropriate • Update zoning code to require pedestrian and bicycle facilities and amenities in commercial and mixed use developments • Establish guidelines for ensuring connectivity between neighborhoods and adjacent land uses • Promote education, enforcement and awareness programs to encourage increased use of and safety for bicycling and walking

  18. Estimated Costs by Category • Roadway = $4,504,029,000 • On System Improvements = $3,532,576,000 • Off System Improvements = $971,453,000 • Capacity Improvements = $3,274,872,000 • Major Intersection Improvements = $798,344,000 • Operational Improvements = $430,813,000 • Transit = $1,132,803,000 (Capital & Operating) • Multi Use Trails = $168,856,000 • Pedestrian = $38,603,000 • Safety & key corridor = $18,103,000 • LCI connectivity = $7,330,000 • School & activity center buffer = $13,170,000

  19. Use of Plan into the Future • To move specific transportation projects forward (prioritization, funding, detailed concept definition) • For project inclusion in ARC’s Regional Transportation Plan (must be drawn from and supported by the countywide CTP) • As a staff resource during interjurisdictional and intercounty coordination efforts • To ensure land use / transportation connectivity and shifting travel behaviors are monitored by Plan updates (every 3-5 years)

  20. Upcoming Outreach • Draft CTP summary and document placed on website from January 23 for public download, review and comment • Final Public Involvement Meeting on January 24 from 3:30-7:30 PM at Central Marietta Library • CTP presentations to local municipality Mayors/Councils for appropriate action
