1 Maryland State Highway Mobility Report Morteza Tadayon

2 Background Mobility is a Key Performance Area (KPA) in the SHA Business Plan SHA adopts a performance based approach Monitors Highway System to identify gaps, needs and opportunities Inform/ Drive Investment Related Decisions 2012 Mobility Report summarizes the highway system performance and SHA s efforts for 2011

3 Key Areas Mobility and Reliability Incident Management And Traveler Information Systems Multi-Modalism/ Smart Growth Freight

4 Stakeholders/ Contributors Stakeholders/ Contributors Maryland State Highway Administration MD Transportation Authority MD Department of Transportation and other Modals MWCOG and BMC MPOs UMD CATT Maryland SHA Offices and Divisions Office of CHART Office of Planning and Preliminary Engineering Office of Highway Development Office of Traffic and Safety Office of Policy and Research UMD CATT and JMT assisted the SHA Travel Forecasting Division to develop the report.

5 Key Datasets and Applications DATASETS INRIX Vehicle Probe Data on freeways/ expressways SHA Traffic Count Data SHA Signal System Data SHA Construction Project Information APPLICATIONS UMD CATT Lab Vehicle Probe Project (VPP) Suite SHA Traffic Monitoring System Application (I-TMS) Traffic Simulation Models and Other GIS Applications

6 AND

7 Vehicle Miles of Travel (VMT) In 2011, drivers in Maryland traveled 56.0 billion vehicle miles VMT in 2011 is about 1% less than the all time high of nearly 57 billion VMT in 2007

8 Congestion Costs for MD Freeways/ Expressways The total estimated statewide cost of congestion on the freeway/ expressway network in 2011 was $1.49 Billion. Cost Breakdown: Auto delay cost: $1,193 M Truck delay cost: $ 259 M Wasted fuel cost: $ 129 M Percent of Total Statewide Congestion Cost by Region (Total Congestion Cost = $1.49B) Baltimore Region Washington Region 3% 3% 34% Percent of Total Statewide Congestion Cost by Source 9% 11% Eastern Shore Western Maryland 60% Travel Delay Truck Delay 80% Wasted Fuel

9 Definitions of Congestion and Reliability Travel Time Index (TTI) : (Average Travel Time/ Free flow Travel Time) = Uncongested (TTI<1.15) = Light (1.15<TTI<1.3) = Moderate (1.3<TTI<2.0) = Severe (TTI>2.0) Planning Time Index (TTI) : (Worst Case Travel Time/ Free flow Travel Time) = Reliable (PTI>1.5) = Moderately Reliable (1.5<PTI<2.5) = Unreliable (PTI>2.5)

10 2011 Congestion on Freeways/ Expressways PM Peak Hour % System Congested Statewide: 13% Baltimore-Washington Region: 20% % VMT in Congested Conditions: Statewide: 26% Baltimore-Washington Region: 29%

11 2011 Reliability Map Freeways/ Expressways % System Unreliable : 11% % VMT in Unreliable Conditions: 26%

12 Bottlenecks (Top 30) REGIONALLY SIGNIFICANT CORRIDORS All Interstates US 50 Maryland 295 US 29

13 Recurring Congestion Projects (2011) Major Projects Inter County Connector (ICC) opened in late 2011 Carries about 25-30K vehicles on an average weekday Diverted traffic from parallel roadways Significant savings in travel times MD 237 from MD 235 to Pegg Road MDTA reconstruction of I-95/ MD 24 and new interchange at MD 24/ MD 924 Minor Congestion Relief Projects Signal System Optimization Projects 48 traffic signal systems involving 298 signals retimed - $21 million dollars in user cost savings Transit Signal Prioritization Projects

14 AND

15 Incident Management and Traveler Information Systems Responded to and cleared more than 17,000 incidents and assisted more than 24,000 stranded motorists in 2011 Delay Reduction of 41.7 million vehicle-hours yielding annual user cost savings of $1.1 Billion. 511 System

16 AND

17 Multi-Modalism and Smart Growth Transit Improvements Major Projects - CCT, Red Line, Purple Line TSP/ Queue Jump TIGER Grant Projects Transit Oriented Developments Complete Streets Bicycle and Pedestrian Accommodations Bicycle and Pedestrian Priority Areas Bicycle Library/ Master Plan Update SHA has budgeted $70 Million for Bike/ Pedestrian improvements

18 Multi-Modalism and Smart Growth HIGH OCCUPANCY VEHICLE (HOV) LANES On I-270: HOV lanes carry 3,100 people per lane compared to 1,900 people per general use lane. On US 50: HOV lanes carry 1,600 people per lane compared to 1,500 people per general use lane. PARK AND RIDE LOTS SHA and MDTA operate lots in 20 of Maryland s 23 Counties Total 12,510 spaces with average 60% occupancy on any given day

25 I-695 Study Example Project Name: I-695, Baltimore Beltway Location of Project: I-695 Outer Loop: MD 144 (Edmonson Avenue) on ramp continuing to MD 372 (Wilkens Avenue) Description: Provide additional through lane from on ramp at Edmonson Avenue to end of acceleration lane from Edmonson Avenue. Project includes widening and restriping of I-695 Outer Loop and removal and placement of retaining wall. Total project length is 2,500 feet. Total User Cost Savings over 10 Years: Auto Delay Cost Savings $ ('000) Truck Total Auto/Truck Fuel Cost Savings $ ('000) Reliability Savings $ ('000) Safety Savings $ ('000) Total Savings 11,427 2,722 14,149 1,415 10, Approx. $27.2 Million Total Cost: $ 18.2 Million (in 2011 Dollars) Project Ranking: 10 out of 16

26 I-695 Study Example (Continued)

27 Next Steps Identify sources of congestion and relief solutions for top bottlenecks Improve reliability of system by focusing on most unreliable segments (ITS, Emergency Vehicle deployment etc.) Conduct Before/ After Studies to evaluate the impact of completed projects Use the Mobility Report as a performance monitoring mechanism to guide decisionmaking Coordination with MPOs, locals and other agencies
