In the United States, motor vehicle crashes resulting in fatalities have declined substantially over the last decade. In the years between 2000 and 2013, the last year for which annual data is available, fatal crashes dropped from a high point of 39,000 in 2005 to 30,000 in 2013.
Crashes are a significant issue for transportation planning due to their impact on the individuals involved as well as the economic impacts on the entire OKI region. Research into the locations where crashes are occurring at a greater rate than the norm can lead to improvement infor the traveling public. data from all three states has been reviewed in the preparation of this plan. Moreover, interagency consultation and cooperation result in advancement of projects which address the region’s needs.

Despite the reduction in fatal crashes, someone dies every 16 minutes in a motor vehicle accident somewhere in the nation.

One of the primary goals of this plan is to improve travel by reducing the risk of crashes that cause death or injuries.
Regional Crash Data
Within the OKI region, over 55,000 crashes occurred in 2013, ending at least 114 lives, and causing more than 12,000 injuries. However, available data indicates that fatalities have been declining in the OKI region in recent years. The uptick in fatal crashes nationwide as well as fatalities in the OKI region in 2012 appear to be anomalies as the counts drop closer to their 2011 levels in 2013.

Bicycle and Pedestrian Crashes
Reported bicycle and pedestrian fatalities in the OKI region have varied little in the past several years. Bicycle deaths have been minimal and pedestrian fatalities have totaled 20 or less annually.

Coordination with Statewide Plans
To reach this plan’sgoals, OKI will coordinate fully with the individual states and local communities in its planning area. In compliance with the Fixing America’s Surface Transportation (FAST) Act requirements that are a continuance of those established in MAP-21, Ohio, Kentucky, and Indiana have developed State Highway Plans (SHSP). OKI’s coordination with the region’s three states’ SHSPs is mandated to “include, at a minimum, high-level goals, objectives and strategies that are consistent with those in the SHSP.” Source: Strategic Highway Plan (SHSP) Interim Guidance, SHWA Office of , April 5, 2013
OKI is contributing to the fulfillment of each individual state’sgoals by analyzing crash data on roadways within the agency’s tri-state planning area. While implementing state and local governmental agencies are responsible for determining engineering improvements to the roadway system, OKI assists in identifying high-risk locations. These analyses result in the identification of locations where needs are greatest in the OKI region. To conduct this analysis, OKI acquires the individual crash records for the most recent five years for which data is available (2009-2013) from each state in the region. Each state gathers different types in different formats which OKI normalizes and combines for analysis.
In the five year period from 2009 through 2013, OKI staff reviewed state crash data and determined that there were 593 fatal crashes on on-system (interstates, other freeways, arterials and collectors) roadways in the OKI planning area. Beyond the potential individual devastation wrought by crashes, the costs of such incidents impact every person in the OKI region. These costs are felt by an incremental loss in productivity due to non-recurring congestion, actual property damage costs and monetary costs associated with medical expenses, increased insurance premiums, and legal fees. Improving travelwill have positive impacts for everyone in the OKI region.
In a review of crash data, a crash rate which is expressed as the number of crashes per hundred million vehicle miles, is a more accurate measure of thecondition of the roadway than a simple crash tally because it takes into account traffic volume.
Crash rates for years 2009-2013 by roadway segment in the OKI region were developed and ranked based on two conditions: the segment’s average daily traffic (ADT) exceeding 2,000 vehicles and a segment length greater than one-tenth of a mile. The 10 highest crash rate locations in each county are highlighted in the interactive map.
Crash rates are used by OKI in its project prioritization process and in identification of dangerous locations to assist state and local agencies in pinpointing transportation needs for further study and, when possible, finding resources to meet those needs.
Countermeasures for Motorized Vehicles
In January 2012, the Federal Highway Administration published a list of nine research-proven roadwaycountermeasures and is advocating their implementation across the country. This list was an update to a list of such countermeasures published in 2008. Source: “Guidance Memorandum on Promoting the Implementation of Proven Countermeasures,” Federal Highway Administration, 2012.
These countermeasures, some new, some carried over from the prior list, include:
- Corridor access management
- Backplates with retroflective borders
- Longitudinal rumble strips and stripes on two-lane roads
- Enhanced delineation and friction for horizontal curves
- Medians and pedestrian crossing islands in urban and suburban areas
- Pedestrian hybrid beacon
- “Road diets” (roadway configuration)
State departments of transportation are encouraged to incorporate these countermeasures when planning transportation projects.
Countermeasures for Pedestrians and Bicyclists
To improve pedestrian and bicycle, the National Highway Administration, in its 2006 Highway Program Guideline No. 14, specifies that the following engineering measures be incorporated into a state’s highway program:
- Pedestrian, bicycle, and school bus loading zone signals, signs and markings
- Parking regulations
- Traffic-calming or other approaches for slowing traffic and improving
- On-road facilities (e.g., signed routes, marked lanes, wide curb lanes, paved shoulders)
- Sidewalk design
- Pedestrian facilities such as sidewalks, crosswalks, curb ramps, and paths
- Off-road bicycle facilities (trails and paths)
- Accommodations for people with disabilities
During the planning period 2010 to 2040, achallenge will present itself in a magnitude not seen previously in the OKI region: the older driver. More than 420,000 persons aged 65 and older are projected to populate the region in 2040, compared with 240,000 in 2010, and will constitute roughly one-fifth of the population of driving age in the OKI region.
Nationally and locally, crash data analysis indicates that the older driver is more frequently involved in right angle crashes and in crashes at intersections compared to the general motoring population. Furthermore, drivers 65 and older are at greater risk for more severe crashes due to bodily frailty.

Countermeasures to help seniors drive more safely include explanatory signage, larger signage, redundant signage, advance notice signage, explicit pavement markings and back plating on signals. All of these countermeasures are low-cost and able to be implemented within the confines of the existing roadway.
After driving, walking is the second most popular means of transportation among the elderly. Source: How the Travel Patterns of Older Adults Are Changing: Highlights from the 2009 National Household Travel Survey by Jana Lynott and Carlos Figueiredo, Fact Sheet 218. Because the elderly may need additional time to cross a street due to shorter stride, slower gait and slower reaction time, educational plaques and leading pedestrian intervals on signals can improve pedestrian.
An added value of countermeasures addressing the needs of the elderly is the fact that they also enhancefor travelers of all ages.
