Lexington Area MPO and LFUCG  Lexington Fayette Urban County Government (LFUCG)  Jessamine County Population – 2015: 314,488 (Fayette Co.) 50,815 (Jessamine Co.) 489,435 (Six Co. MSA)

Purpose and Preview  Traffic Congestion measures and travel-time reliability  BlueTOAD application introduction and overview  BlueTOAD data collection and processing capabilities  How can Google live and typical traffic maps help  Other data sources, tools, and present/future work

What is Traffic Congestion? “The level at which transportation system performance is unacceptable due to traffic interference and excessive travel times/delays. ” The level of system performance deemed acceptable by State and local officials may vary by type of transportation facility (major or minor arterial), geographic location (urban or rural area), and/or time of a day. Source: 23 CFR Sec. 500.109

Types of Congestion 1. Recurring 2. Non-recurring

Recurring Congestion  Causes of Congestion  Bottlenecks, lack of lane/road capacity  Excess Demand  Commuters & SOVs  Seasonal  Long-term construction

Non-Recurring Congestion  Causes of Congestion  Crashes/Incidents  Disabled Vehicles  Special Events  Weather  Utility Work / Maintenance / Short-term Construction  Goods and Service Deliveries

How to measure congestion and travel time reliability? Three (3) indices and formulas have been recognized by FHWA to measure congestion and Travel Time (TT) reliability. Travel Time Index (TTI):  TTI = Average Travel Time (TT) / Free Flow TT Buffer Time Index (BTI):  BTI = (90 th or 95 th TT – Average TT) / Average TT Planning Time Index (PTI):  PTI = 90 th or 95 th TT / Free Flow TT Source: www.ops.fhwa.dot.gov/

BlueTOAD (Bluetooth Travel-time Origination And Destination)  Reliable data using MAC address pairing  Cellular and/or Ethernet communications  Real-time network and device monitoring  For use on arterials and freeways

How BlueTOAD system works? Hardware: Web based Backend: Filters/Algorithms: Web Hardware based

BlueTOAD Benefits Transportation Planning • • Collect data for transportation planning and traffic modeling • Help identify, develop and prioritize projects • Collect data for before & after studies to report the effectiveness of improvement projects • Congestion Management • Identify congested roadway segments and intersections • Determine congested time of a day and duration • Quantify congestion levels using congestion indices • Monitor congestion changes over time and trends.

BlueTOAD Benefits Signal Timing • • Testing of coordination plans to ensure effectiveness • Ability to collect data in order to measure construction impacts. • Ability to compare time of day coordination plans in order to choose most appropriate plan. • Emergency Services • BlueTOAD can be use to measure accident clearance times. • Can be used to measure lasting affect that a collision may have on traffic before returning to normal.

BlueTOAD Information Comparisons

Bluetooth Technology Pros and Cons Advantages: Disadvantages:  Mobile Units allow for  Monthly Costs flexibility with data capture.  Possible Coverage Issues  Customize Sample Periods  Maintenance  Compare multiple traffic events.  Calculate Congestion and reliability Indices  Publish travel times to the public
