14 How to read the MUTCD?

15 Does the MUTCD Apply to My Road? Yes! The MUTCD governs the design and use of traffic control devices for all streets, highways, bikeways, and private roads open to public travel regardless of type or class or the public agency, official, or owner having jurisdiction.

16 Liabilities and Risk You can t eliminate risk but you can manage it Liabilities Regulatory: while there is no MUTCD Police, you may find that you can t get certain funding if your signs and markings are non-compliant Constituents: your residents expect safe roads Tort liability: signs and pavement markings are low-hanging fruit for plaintiffs attorneys End up in my workshop slides!

17 PART 1 GENERAL INFORMATION Section 1A.08 Gives local agencies the authority to place traffic control devices. All regulatory traffic control devices shall be supported by laws, ordinances, or regulations. Need a local ordinance for speed limits (nonstatutory) Indiana Code Stop & Yield Signs Statutory Speed Limits

18 PART 1 GENERAL INFORMATION Section 1A.09 The decision to use a particular device at a particular location should be made on the basis of either an engineering study or the application of engineering judgment.

19 PART 1 GENERAL INFORMATION Section 1A.13 Definitions 64. Engineering Judgment Evaluation of available pertinent information Documentation of engineering judgment is not required 65. Engineering Study Comprehensive analysis and evaluation An engineering study shall be documented

21 PART 2 SIGNS Section 2A.05 Classification of Signs A. Regulatory signs give notice of traffic laws or regulations. B. Warning signs give notice of a situation that might not be readily apparent. C. Guide signs show route designations, destinations, directions, distances, services, points of interest, and other geographical, recreational, or cultural information.

22 PART 2 SIGNS Section 2A.06 Design of Signs Uniformity in design shall include shape, color, dimensions, legends, borders, and illumination or retroreflectivity. We have limited time to get the message across. Standard designs aid in intuitive recognition.

45 PART 1 GENERAL INFORMATION Section 1A.13 Definitions 123. Multi-Lane more than one lane moving in the same direction. A multi-lane street, highway, or roadway has a basic cross-section comprised of two or more through lanes in one or both directions. A multi-lane approach has two or more lanes moving toward the intersection, including turn lanes.

46 PART 2 SIGNS Sections 2A-11 Dimensions The sizes shown in the Minimum columns shall only be used on lowspeed roadways, alleys, and private roads open to public travel where the reduced legend size would be adequate for the regulation or warning or where physical conditions preclude the use of larger sizes.

48 PART 2 SIGNS Shall be installed on righthand side At intersections where all approaches are controlled by STOP signs, an ALL WAY supplemental plaque shall be mounted below each STOP sign.

49 PART 2 SIGNS All Way Stops Requires engineering study Equal Volumes? Correctable Crash History? Pedestrian Conflicts? Sight Distance Issues? Left-Turn Conflicts? NOT for speed control

50 PART 2 SIGNS Section 2B.10 When STOP sign visibility is restricted, a Stop Ahead sign shall be installed in advance of the STOP sign.

51 PART 2 SIGNS Section 2B.10 Stop & Yield Sign Placement Locate as close as practical to intersection, while optimizing visibility Locate no farther than 50 feet from edge of intersecting road Where two roads intersect at an acute angle, the STOP or YIELD sign should be positioned at an angle, or shielded, so the legend is out of view of traffic to which it does not apply.

122 MUTCD FAQs 1. When an INDOT road passes thru a city/county who does which TCDs? 2. Should I use slow children signs? 3. Do all the activities associated with a compliance have to be done by that date? 4. When do I have to switch to upper & lower case letters on street blades? 5. What s the difference between a Dead End and No Outlet sign?

123 MUTCD FAQs 6. How do I change the speed limit? 7. Can I still use engineering grade sheeting? 8. My councilman wants a signal at this intersection, how do I do that? 9. Do I have to sign every curve in my county? 10.Can I install shorter signs so farm equipment won t always hit them? 11.How do I determine no-passing zones? 12.Why is INDOT using flashing yellow arrows for left turns, and do I have to do that too?

135 How TCDs Get into MUTCD 1. New Traffic Control Device idea o Idea for a new traffic control device that improves road user safety or operation 2. Experimentation o o o Experimenter" must evaluate conditions both before and after installation Results show that the public understands the new device, performs as intended, and does not cause adverse conditions. REQUIRE FHWA APPROVAL 3. Interim Approval o o o Allow the interim use, of a new traffic control device, not specifically described in the MUTCD. Interim Approvals are issued based on the results of successful experimentation, studies, or research, REQUIRE FHWA APPROVAL 4. Incorporated into MUTCD o Next edition or Revision

136 Experimental and Interim Approvals Experimentation o o RESTRICTED - Requires FHWA Approval to conduct experiment. Agency COMMITs to Implementation: Controlled Conditions, Limited Locations and Time, Data Collection, Analysis: before and after study, measures of effectiveness, benefits, Research Report. Interim Approval o o o CONTROLLED Requires FHWA Approval/Grant Permission for use. Approves use Jurisdiction Wide - State DOT may request Statewide use Agency AGREEs to: Comply with Conditions in IA. Maintain Inventory List Comply with 1A.10 of MUTCD - maintain devices, terminate use if IA revoked

145 Crosswalks

146 Crosswalks FHWA has provided many interpretations on crosswalk design since 2001 Aesthetic treatments do not reduce crashes or provide a safety benefit Retroreflectivity in aesthetic treatments is prohibited Crosswalk art degrades contrast of required white lines

147 Crosswalks Why do we maintain a strict policy?

148 Crosswalks Latest Official Ruling 3(09)-24(I) Agencies are not permitted free reign over area between transverse lines Limited aesthetic treatments are permitted Bricks, pavers, cobbles, simulated versions thereof Treatment must be uniform and consistent No pictographs, symbols, attempts to communicate Full text available on MUTCD website under Interpretations

149 Crosswalks Compliant aesthetic treatments

150 Crosswalks Why do we maintain a strict policy? Crosswalks must be recognized and understood in a moment The MUTCD-standard crosswalks are tested and verified for road user understanding Purpose of any aesthetic treatment is to draw the eye no safety or operational purpose

151 MUTCD Hot Topics

152 Bicycle Traffic Control Interim Approval 14 Green Colored Pavement Markings for Bicycle Lanes

153 Two-Stage Bicycle Turn Box Interim Approval 20-1 Area set aside for bicyclists to wait to turn across traffic (left) without requiring a merge

154 Intersection Bicycle Box es Interim Approval 18 Provides bicycles a designated area on the approach to a signalized interstation in front of stopped vehicles during the red signal phase so that they are more visible to motorists.

155 Pictographs/Street Name Signs Section 2A.06 Pictographs Simple, dignified, and devoid of any advertising The official designation adopted by a political jurisdiction The official seal adopted by a college/university NOT a Logo Section 2D.43 Street Name Signs Height and width shall not exceed the Upper-case letter height of the street name The pictograph should be positioned to the left of the street name NO: Yes:

156 Bridges!

157 Bridge Safety Low Clearance SHALL warn road users of clearances less the 12 inches above the statutory maximum vehicle height. (Section 2C.27) W12-2 W12-2a INDOT - the W12-2 sign in advance of the restriction, when the vertical clearance is less than or equal to 14-6, with additional signing or conspicuity enhancement measures, such as fluorescent yellow sheeting, used on a case-by-case basis

158 Bridge Safety Load Posting A bridge must be posted if any of the State legal or routine permit rating factors is <1.0 for any of the required vehicles. Per INDOT policy, at a minimum R12-1 (single tonnage) shall be used. R12-5 (silhouette sign) should be used at the discretion of the bridge owner. Sign will list a minimum tonnage for vehicles with 2-axles, 3-axles, and 4 or more axles. Per the MUTCD 6F.10, R12-1 is required at the bridge; however it is also recommended at the intersection(s) prior to the bridge (best practice).
