We need your input for the 4th Edition
The MMUCC Expert Panel will be meeting April 12-14 to consider possible changes to the 3rd Edition of the MMUCC Guideline. The planned publication of the 4th Edition is roughly 1 year away (spring 2012). Now is the time for you to tell us what you think should or should not be in the 4th Edition. Among the major issues that will be discussed by the Expert Panel are the addition of a Speeding Related element to better capture crashes in which speeding was involved, expansion of the Driver Distracted By data element, adoption of a better set of defintions for the Injury Status KABCO attributes, and a model PAR -- Model Minimum Uniform Crash Report (MMUCR). Other data element changes will also be considered, so if there's an existing data element that you think needs to be revised or even dropped, post your thoughts here.






Alabama will also be keeping
Posted by David Brown on March 24, 2011 - 10:27amAlabama will also be keeping all data elements. As of June 2009 we revised almost all of our data elements going to a paperless submission system (eCrash), and the PDO screens are the same as those for injury crashes. Our officers are as strapped for time as in any other state -- but the time they save using eCrash generates more than enough to complete the PDO crashes. Of course, being able to complete and submit their reports from their cars also keeps them in the field and ready to respond to any emergency, so it is really not lost time. The question that must be asked is: "Could the data element that is being sacrificed ever be useful in determining why a crash is a PDO and not an injury or a fatality?" If the data element could never serve this purpose, or if there is no intention within the state to answer that question in the future, then those data elements could be sacrificed. We could not find enough that qualified to warrant two different submissions or to justify the additional problems created by not being able to compare results between injury and non-injury crashes.

Posted by Tom Bragan on March 29, 2011 - 11:53amDavid -- Thank you for your response to David Bozak's post on the Crash Elements thread regarding his proposed PDO set of data elements. You make some good points, particularly in regard to comparibility of injury and non-injury crashes.
Reduce the minimum criteria
Posted by Gary Mower on March 24, 2011 - 12:15pmReduce the minimum criteria for all crashes. A few simple suggestions are: combine C13 & C14; combine C15 & C16; combine P17 & P19; combine P18 & P20; delete C17 & V22 as they are already picked up in V8. Also some of the attributes can be deleted or combined. For example, in P25 is it really worthwhile to know if a nonmotorist was wearing elbow or knee pads?
Alaska has many trails along
Posted by Joanna Reed on March 25, 2011 - 4:23pmAlaska has many trails along the roadsides dedicated to snowmobiles and all terrain vehicles (ATVs). These trails are within the trafficway, and related crashes are therefore being collected in our state system and in FARS. Although knowledge of these crashes is benificial, many folks in the Alaska Highway Safety community believe including them in our systems with crashes which occur on the roads involving regular vehicular traffic is causing our statistical results to be imprecise. We would like a way to include them but seperately. Perhaps a code somewhere for crashes involving motor vehicles which were never being driven on the roadway itself, but rather in the trafficway.

Posted by Tom Bragan on March 29, 2011 - 11:50amJoanna -- Thank you for your comment. One possible new data element that will be discussed at the April Expert Panel is a Traffic/Non-Traffic element, which is intended in part to help identify motor vehicle crashes that occur outside the trafficway. Within the existing data element Location of First Harmful Event Relative to the Trafficway there are attributes for locations inside the trafficway, both on and outside the roadway.
Idaho has just revised the
Posted by Steve Rich on March 28, 2011 - 11:46amIdaho has just revised the crash data collected to be more MMUCC compliant (at least to the 3rd edition) and is implementing the new software in 2011. Idaho has no plans to create a shorter report for PDO crashes.
Distracted Driving codes
Posted by Douglas Mowbray on July 20, 2011 - 12:31pmIn Maryland, we are developing a new electronic crash report and our intent is to make it as MMUCC-compliant as possible. We anticipated the need for more detailed codes for the Distracted Driver By field and came up with a list prior to seeing MMUCC 4 recommendations. After an initial list of codes was considered, we looked to the FARS Coding Manual. The new Pre-Crash coding form in FARS is more detailed for Driver Distracted By. Below is our proposed list of codes for the new Maryland crash form, which has a few more codes than MMUCC 4:
Looks good!
Posted by Tom Bragan on July 21, 2011 - 8:06amMr. Mowbray,
It looks to me as if all of MD's proposed distraction codes either match or could be easily mapped to the proposed 4th Edition MMUCC Driver Distracted By attributes. I'll forward the list to NCSA's driver distraction analyst to see if she has any comments.
Other Pedestrian
Posted by Douglas Mowbray on August 22, 2011 - 10:24amIn Maryland, we are also looking to expand the codes for Other Pedestrian. The proposed MMUCC 4 revision includes the following: Other Pedestrian (wheelchair, person in a building, skater, personal conveyance, etc.)
We'd like to see that broken out so we can distinguish certain groups in our datasets, e.g., wheelchair, skateboard, in house, construction workers, especially the construction workers, as opposed to someone else on the work zone site.
Observations regarding the proposed MMUCC Fourth Edition Changes
Posted by David Bozak on July 27, 2011 - 3:16pmIncrease in (C) Crash level data elements from 18 to 19
Increase in (P) Person level data elements from 27 to 28
Workgroup has done well – increasing only 2 “at scene” data elements from 75 to 77. Did Workgroup talk about earlier suggestions to combine C13 & C14; or C15 & C16; or P17 & P19 or P18 & P20? One we would suggest would be to combine V6 & V7.
Emergency MV Use – liked the improved attribute descriptions
Name of Person Involved – good idea, instead of just Name of Driver
Injury Status – liked the improved attribute descriptions, which expanded on the D16 definitions. We are torn between the two options. Would probably opt to keep KABCO intact
Speeding – unsure about removing the “speed” attributes from Driver Actions; however, seeing that Driver Actions also do not include “alcohol related” – it treats these two driver extreme actions separately from Driver Actions. Speeding will still be difficult to record, but we’ve got to make the attempt through MMUCC
Driver Distracted – correction change – this should be P16. Which list is closer to the FARS attributes – the proposed 4th Edition MMUCC listing or the Maryland listing?
Looked for a definition for a non-traditional vehicle; couldn’t find. Only thing I saw in D16 was Personal Conveyance. I’m sure the category includes much more than those.
Vehicle Removal – liked the removal of the sentence … “Estimation of damage to vehicle” – fits in with what the Connecticut TRCC is proposing to pilot test, which would be a towed due to damage threshold.
Condition – Data element still refers to Driver & Non-Motorist; however the first subheading refers only to Driver
Regarding the PDO question; we will talk during the Wednesday morning session - some about the MMUCC Forum PDO question posed a few months ago; and the 21 states who responded. Connecticut is hoping to pilot test a “question-based/turbo tax type of approach” recommending complete upgrade to MMUCC.
With “question-based” electronic crash reporting, we are looking to exclude all questions that are not applicable to the crash. “Vehicle towed due to damage” would be a criteria for recording all of the related MMUCC elements for a PDO; however, if damage was modest, towing wasn’t required and there was no egregious hazardous traffic violation, this might lead to a second (abbreviated) level of reporting for PDOs; excluding the following, which would be recommended for complete MMUCC.
a) crashes involving death or injury, b) crashes involving non-motorists, c) crashes involving school buses, and d) crashes involving commercial motor vehicles
Response to Dave
Posted by Tom Bragan on July 29, 2011 - 9:36amDave -- Thanks as always for your thoughtful comments and insights.
Did Workgroup talk about earlier suggestions to combine C13 & C14; or C15 & C16; or P17 & P19 or P18 & P20? One we would suggest would be to combine V6 & V7.
No, the Panel did not consider combining these elements. While I do appreciate the idea of reducing the total number of data elements, some panel members have in the past made it clear that they prefer to avoid "combo" elements with multiple subfields.
Driver Distracted – correction change – this should be P16. Which list is closer to the FARS attributes – the proposed 4th Edition MMUCC listing or the Maryland listing?
The new Maryland Distracted Driving attributes as posted by Doug Mowbray are almost an exact match of the 2010 FARS Driver Distracted By attributes, providing more detail than the proposed 4th Edition MMUCC Driver Distracted By -- which, since MMUCC is intended to be a minimum set, is an understandable and welcome difference.
Looked for a definition for a non-traditional vehicle; couldn’t find.
This is one of the more important of many definitions still to be refined and added to the glossary.
I look forward to hearing more of Connecticut's pilot test and progress
