Arterial Management Plan for US Route 250 and State Route 623

1 Arterial Management Plan for US Route 250 and State Route 623 June 25, 2014 Brad Shelton, AICP Access Management and Traffic Impact Analysis Programs Manager Transportation and Mobility Planning Division

2 Arterial Management Plans The CTB developed a planning process for the Corridors of Statewide Significance and directed pilot studies to refine the process. Their concern is that future funding is not available to rebuild facilities that are inundated by local traffic generated by land development. Focus on corridor where considerable development is likely within 10 years Similar to functional plans of past, work with localities to develop corridor management plans that address: thoroughfare improvements intersection/interchange improvements access points and median treatments operational improvements signal optimization, triggers for provision/improvement interparcel access and connections set back requirements, ROW preservation Transportation Demand Management (TDM) strategies 2

12 Goal AMP Program Facilitate and support local land development goals Preserve mobility and safety Support economic development and vitality of study area Maximize transportation system efficiency and minimize public investment required to support local development goals Use pilot studies in Goochland and Spotsylvania to build a streamlined methodology and approach Institute annual work plan to identify and develop plans throughout the state for corridors with high risk of land development within next 10 years 12

13 Pilot Locations Spotsylvania County Route 3 from Orange to Gordon Road 13

14 Route Arterial Management Plan Broad Street (US 250) from Hockett Road to Goochland CL/Henrico CL Ashland Road (RT 623) from Broad Street to Forest Road 10 Study Intersections Centerville Village Hockett Road Source: Google Maps 14

19 Summary of Corridor Crashes 19

20 Field Observations 20

21 Inventory of Existing Access Points 21

22 Current Transportation Issues Route 288 at Broad Street Interchange Ramp Terminals Large turning movement volumes, queuing Pattern of angle crashes East ramp terminal - NB approach LOS F Signing is not clear which ramp to take East ramp terminal - poor sight distance from NB approach looking west Ashland Road at I-64 Interchange Large turning movement volumes No turn lanes, queuing EB and WB approaches LOS E or F Pattern of rear end and angle crashes High speeds along Broad Street 22

23 Review of Planned Area Improvements 23

24 Stakeholder Interviews Identified List of 10 Stakeholders Property Owners Real Estate Developers Regional Local Planning Commissioner Residents Questionnaire Used to Gain Input Current transportation Issues Future development (i.e. types, density) Types of Improvements Operational Improvements Safety Improvements Access Management Geometric Improvements Policy Changes Public Meeting to Present Existing Conditions 24

25 US 250 & Route 623 Arterial Management Plan FUTURE CONDITIONS 25

26 Background Growth Rates Background Traffic = Existing Traffic + Growth in Existing Traffic 26

27 Future Land Use Assumptions based on: Centerville Land Use Plan Coordination with County Staff and Stakeholders Scenario 2 (Higher Intensity) Includes 15% Internal Capture Reduction for Mixed Use Includes 30% Pass-By Reduction for all Commercial Use Assumed Zones 5 and 6 were built out Results in 110,309 total daily site trips 27

28 Future Trip Distribution Assignment of trips generated by assumed development 28

29 Minimally Managed Access Scenario 29

30 Optimally Managed Access Scenario Introduced additional signal on Broad Street Eliminated all full movement unsignalized access points Reduced total number of access points by 26% 30

31 Operational Analysis MMAS vs. OMAS OMAS operates comparable to MMAS with less overall access points and the addition of one more traffic signal Additional capacity required: Ashland and Plaza Ashland and Rockville 31

32 Safety Analysis MMAS vs. OMAS Reducing conflict points may reduce crashes Implementing access management reduces the number and severity of conflict points Reduction in number of conflict points 32

33 US 250 & Route 623 Arterial Management Plan RECOMMENDATIONS 33

34 Recommendations Toolbox Purpose: To ensure the safety and preserve the capacity of the Commonwealth s arterial highway network without wide scale roadway widenings. 34

35 Major Roadway Recommendations Widen Ashland Road from 2LU to 4LD Already in Major Thoroughfare Plan Future volumes suggest 4 Lane demand occurs within 5 10 years Existing Right of Way = 90 to 150 feet Three-Chopt Road Widen from 2LU to 4LD Upgrade in conjunction with development Existing Right of Way = Prescriptive Extend Across Route 288 Conduct feasibility study of extension Requires further study to determine scope improvements Already in Major Thoroughfare Plan 35

36 Connectivity Recommendations Connectivity key to managing traffic on study corridors Connections Included in Major Thoroughfare Plan (MTP) Exact locations to be determined Extension of Three Chopt Road across Route 288 Interchange at I-64 and Ashland Road Various connections to/from Broad Street and Ashland Road Recommend Hockett Road Extension Revise MTP Add 5 proposed connections Utilize full movement access points Remove 1 connection 36

37 Access Management Recommendations Implement corridor access as shown in AMP Type of access Spacing shown Number of access points Partnership with Goochland County and VDOT to implement recommendations 37

38 Interchange Recommendations Short Term Route 288 at Broad St Install Traffic Signals Northbound Route 288 Ramp Terminal Signalize NB to EB right-turn movement Add 2nd lane on NB Route 288 to EB Broad Street Off-Ramp and signalize Southbound Route 288 Ramp Terminal Additional Turn-Lanes I-64 at Ashland Rd Install traffic signal at EB I-64 Onand Off-ramps 38

39 Interchange Recommendations Longer Term 2035 No-Build, Level of Service = F Target Critical Turning Movements WB to SB Directional Ramp WB to NB Directional Ramp Route 288 at Broad Street Interchange» Does not prohibit development within interchange area» Interchange Modification Report 39

40 Interchange Recommendations Longer Term I-64 at Ashland Road Interchange Not constrained by development within interchange area Preserve right-of-way within footprint as development occurs Already included in Major Thoroughfare Plan Conduct Comprehensive Long-Range Interchange Study High-level design, fatal flaws analysis Refinement of alternatives Interchange Modification Report 40

41 Intersection Recommendations Turn Lanes Traffic Signals AMP potential for 11 total Roundabouts VDOT Policy Potential locations Ashland Road at Three Chopt Road Ashland Road at Rockville Road Ashland Road at Plaza Drive Ashland Road at Broad Street Additional analysis needed 41

42 Bike & Pedestrian Recommendations Comprehensive Plan Incorporate safe pedestrian and bicycle pathways into village plans and other plans where practical Recommend Multi-Use Paths Locate on both sides of roadway Setback from Roadway Physical separation Higher traffic volumes and speeds As roadways are improved In conjunction with development Provides access to all users Logical connections One component of bike and pedestrian plan 42

43 Travel Demand Management Park & Ride Lots Existing PNR Lot at I-64 and Ashland Road VDOT owned parcel at Route 288 and Broad Street Transit As development occurs In conjunction with Mixed-use Start the conversation Public meeting held to present recommendations 43

44 Policy Incorporate AMP recommendations as part of Comprehensive Plan Update Comprehensive Plan Every 5 years as required by law 44

45 Tasks Remaining Finalize AMP Report Sample cross-sections Suggested right-of-way Provide information for completing funding applications / IMRs Cost estimates Plan Adoption Anticipated July Finalize Methodology Report Coordinate with Baker and Route 3 AMP Route 106 AMP New Kent 45
