Indiana MUTCD: for Operations & Maintenance Issues/Solutions – Part II

Presentation Overview This presentation will highlight some of the following issues in Parts 3-4 and 7-8 of the 2009 National MUTCD and the 2011 Indiana MUTCD Draft: New Developments Indiana Differences Common Issues

Part 3 - Markings Chapter 3A – General (Functions of Longitudinal Markings) Line Types: Double line prohibits crossing Solid line discourages crossing (prohibits in some cases). Broken line indicates permissive condition Dotted line warns of change in lane function Line Patterns: Broken (skip) line is 10 ft. segment and 30 ft. gap Dotted line is 3 ft. segment and 9 ft. gap. When used as intersection markings, the dotted line pattern is a 2 ft. segment and 2-6 ft. gaps.

Part 3 - Markings Chapter 3B – Pavement and Curb Markings (Centerline and Edgeline Warrants) Centerlines: At least 4,000 ADT and 20 ft. pavement width for pavement for urban roads. At least 3,000 ADT and 18 ft. pavement width for rural roads. Edgelines: At least 3,000 ADT and 20 ft. pavement width for rural roads. Not required for urban roads except on freeways and expressways.

Dotted (not broken) lane lines shall be used in the following applications: - Lane drops (wide dotted) - Auxiliary lanes (wide dotted) - Acceleration lanes (normal width dotted) - Deceleration lanes (normal width dotted) Applies on freeways, expressways, and conventional roads Part 3 - Markings Chapter 3B – Pavement and Curb Markings

Lane drops on freeways and expressways Part 3 - Markings Chapter 3B – Pavement and Curb Markings

Lane drops on conventional roads Part 3 - Markings Chapter 3B – Pavement and Curb Markings

Auxiliary Lanes Between Ramps - if < 2 Miles Part 3 - Markings Chapter 3B – Pavement and Curb Markings

Auxiliary Lanes Between Intersections - if < 1 Mile Part 3 - Markings Chapter 3B – Pavement and Curb Markings Now to be wide dotted lane line

Dotted Lines on Acceleration Lanes Part 3 - Markings Chapter 3B – Pavement and Curb Markings

Dotted Lines on Deceleration Lanes Part 3 - Markings Chapter 3B – Pavement and Curb Markings

The compliance date for these new dotted lines is: December 31, 2016; or Resurfacing, whichever occurs first Part 3 - Markings Chapter 3B – Pavement and Curb Markings

Delineators are required on the right-side of: Interstates & Freeways Exit Ramps Divided Highways Part 3 - Markings Chapter 3F – Delineators Exceptions are on tangent sections of these roadways where raised pavement markers or continuous lighting is provided.

Part 4 - Signals Chapter 4E – Pedestrian Control Features (Countdown Displays Required at New Pedestrian Signals)

Part 4 - Signals Chapter 4E – Pedestrian Control Features (Pedestrian Crossing Speed) 3.5 ft/sec instead of 4 ft/sec during concurrent green indication 3.0 ft/sec for total crossing time (may include yellow and all-red phases) The steady don’t walk symbol must be displayed during the yellow and all-red phases Compliance date is December 31, 2014

Part 4 - Signals Chapter 4E – Pedestrian Control Features (Pedestrian Crossing Speed) Option to still use 4 ft/sec crossing speed if pedestrians can use a push button to get additional time:

Part 4 - Signals Chapter 4F – Pedestrian Hybrid Beacons (Warrants For Use)

Part 7 – Traffic Control for School Areas School Signs Specific to the Indiana MUTCD

Part 7 – Traffic Control for School Areas School Speed Limit Signs School speed limits should begin 200 ft. in advance of the school grounds if the reduced speed is 25 mph. School speed limits should begin at least 200 ft. in advance of the school grounds if the reduced speed is 30 mph and above.

Part 8 – Traffic Control for Railroad Crossings Chapter 8B – Yield or Stop Signs Required at Passive Crossings Compliance Date – December 31, 2019

Part 8 – Traffic Control for Railroad Crossings Railroad Abandonments IC requires a Tracks Out of Service Sign (R8-9) at abandoned railroads. INDOT maintains the railroad abandonment list at:
