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.
Part 3 - Markings Dotted (not broken) lane lines shall be used in the following applications: Chapter 3B – Pavement and Curb Markings • 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 Lane drops on freeways and expressways Chapter 3B – Pavement and Curb Markings
Part 3 - Markings Lane drops on conventional roads Chapter 3B – Pavement and Curb Markings
Part 3 - Markings Auxiliary Lanes Between Ramps - if < 2 Miles Chapter 3B – Pavement and Curb Markings
Part 3 - Markings Auxiliary Lanes Between Intersections - if < 1 Mile Chapter 3B – Pavement and Curb Markings Now to be widedotted lane line
Part 3 - Markings Dotted Lines on Acceleration Lanes Chapter 3B – Pavement and Curb Markings
Part 3 - Markings Dotted Lines on Deceleration Lanes Chapter 3B – Pavement and Curb Markings
Part 3 - Markings The compliance date for these new dotted lines is: Chapter 3B – Pavement and Curb Markings • December 31, 2016; or • Resurfacing, whichever occurs first
Part 3 - Markings Delineators are required on the right-side of: Chapter 3F – Delineators • Interstates & Freeways • Exit Ramps • Divided Highways Exceptions are on tangent sections of these roadways where raised pavement markers or continuous lighting is provided.
Part 4 - Signals Chapter 4C – Traffic Control Signals Needs Studies (Warrant 9 – Intersection Near a Railroad Crossing)
Part 4 - Signals Chapter 4C – Traffic Control Signals Needs Studies (Warrant 9 – Volume Adjustment Factors)
Part 4 - Signals Chapter 4D – Traffic Control Signal Features (Red Arrows for New Left Turn Signals)
Part 4 - Signals Chapter 4D – Traffic Control Signal Features (Option for Flashing Yellow Arrow at Permissive Lefts)
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 Pedestrian Hybrid Beacons May Also Be Used for Emergency Vehicle Access
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 8-6-15-3 requires a Tracks Out of Service Sign (R8-9) at abandoned railroads. • INDOT maintains the railroad abandonment list at: • http://www.in.gov/indot/files/Abandupdate2010.xls
