I. Introduction: The 2006 Annual 5 Percent Report
top
On August 10, 2005, President George W. Bush signed into law the Safe, Accountable,
Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU).
SAFETEA-LU establishes a new core Highway Safety Improvement Program (HSIP)
structured and funded to reduce fatalities on all public roadways. A provision
of the new HSIP requires all states to submit an annual report to the Federal
Highway Administration (FHWA) by August 31 of each year describing not less
than 5 Percent of their public roadway locations exhibiting the most severe
safety needs [Section 148(c)(1)(D)]. This first year the California report is
due September 27, 2006. Subsequent to the passage of SAFETEA-LU, the FHWA issued
guidance1 to facilitate states’
response to the 2006 Annual 5 Percent Report. This report satisfies the requirements
detailed in United States Code, Title 23, Section 148(c)(1)(d) and complies
with the FHWA guidance.
II. The 2006 Annual 5 Percent Report Purpose
top
The California 2006 Annual 5 Percent Report is not intended to be used as a
tool for the allocation of funding for, or prioritization of, State roadway
safety projects.
The California 2006 Annual 5 Percent Report serves to:
- Satisfy the HSIP reporting requirement – The 2006 Annual 5 Percent Report is one of four reports required by SAFETEA-LU in addition to the development of an approved Strategic Highway Safety Plan (SHSP) if the State is to receive its full apportionment of federal HSIP funding.
- Raise public awareness of the safety needs and challenges in the State – In accordance with SAFETEA-LU, the United States Department of Transportation (USDOT) will facilitate public awareness by placing the approved 5 Percent Report for California and all other state’s Annual 5 Percent Reports on the USDOT Web site.
- Raise awareness of the importance of traffic safety data – The locations identified in the 2006 Annual 5 Percent Report are based on available roadway and collision data for the State Highway System only (city and county roadway locations are not included for the 2006 report). In order for California to report on locations for all public roadways, California will need to examine available data sources and data collection methods to identify associated deficiencies.
III. Collision Factors top
The Venn diagram in Figure 1 shows collisions result from one or a combination
of three factors: the vehicle, the driver, and the road. For example, a collision
may result from faulty brakes, an impaired driver, or a curve that is too tight
for the prevailing speed.2 As a nation,
12 percent of all collisions involve some factor of the vehicle traveling the
roadway; 34 percent involve some characteristic of the roadway, and 93 percent
were due to human factors. When situations involving other collision factors
are removed the data attribute the majority (57 percent) of traffic collisions
to human factors. This information shows the importance of a holistic approach
to roadway safety. To provide safer trips on California’s roadway system,
efforts to improve roadway safety need to focus on engineering, education, enforcement,
and emergency medical services (4Es).
Figure 1 - Collision Factors3

IV. California Roadway Data top
Table 1 shows California’s roadway information segmented by city streets,
county roads, and State highways [roadways maintained by the California Department
of Transportation (Caltrans)]. City streets and county roads have roughly similar
lengths of maintained miles and lane miles; however, data show that city streets
carry much more traffic than do county roads. A review of the State Highway
System reveals that, even though the State Highway System constitutes fewer
maintained miles and lane miles than city and county roads, the State Highway
System carries the majority of vehicle miles traveled (VMT) in California.4
| Roadway | Total Maintained Miles | Lane Miles | Total Annual VMT in Millions |
|---|---|---|---|
| City Streets | 73,703 | 164,253 | 113,781 |
| County Roads | 65,324 | 132,601 | 31,113 |
| State Highway | 15,209 | 50,525 | 182,906 |
| Total: | 154,236 | 347,378 | 327,800 |
V. The California 5 Percent Report Methodology
top
Caltrans assembled a team of traffic safety stakeholders to analyze available
data and explore approaches to identify locations for the 2006 Annual 5 Percent
Report. The team included: California Highway Patrol (CHP), Caltrans, Department
of Motor Vehicles, League of California Cites, County Engineers Association
of California, California State Association of Counties, the Traffic Safety
Center – University of California Berkeley, and the Federal Highway Administration
(FHWA). The team determined that available statewide data was insufficient to
identify locations on all public roadways (State and local). Caltrans (state
highways only), has data, processes and procedures in place to analyze and report
on locations for the State Highway System; The Traffic Accident Surveillance
and Analysis System (TASAS) managed by Caltrans. Therefore, the team opted to
use the established process and data for the 2006 Annual 5 Percent Report as
allowed by the FHWA Guidance,6 and will
endeavor to include local roadway information for the 2007 report.
The Traffic Accident Surveillance and Analysis System
top
Caltrans uses TASAS to identify locations with significantly high collision
concentrations during the preceding three year period. The identified locations
are systematically investigated to determine probable cause of the collisions
and implement effective countermeasures to improve safety. There are approximately
7,000 traffic safety investigations completed each year, which consist of detailed
analysis of collision history, collision diagrams, field investigations, and
a review of roadway geometrics. Each investigation has a recommendation, which
is either to undertake an improvement or to make a determination of no action.
Improvements can range from maintenance work orders or sign installation orders
to minor or major improvement projects. Each recommendation is followed-up to
ensure implementation.
Caltrans collects fatal, injury (severe, minor, and complaint of pain), and property damage only collision information from the CHP Statewide Integrated Traffic Record System, maps the collisions to the State Highway System contained in TASAS, and then segments the roadway into 0.2 mile lengths for analysis. All State Highway System locations are identified as a roadway segment, an intersection, or a ramp (which includes the intersections between the ramp and local road). Next, TASAS divides State Highway System locations into rate groups, which factor in geometrics, volumes, and other relevant factors. TASAS also considers other factors and applies rates to roadway segments (per million vehicle miles), intersections (per million vehicles) and ramps (per million vehicles) to allow for location comparison. Then TASAS compares individual locations to facilities with similar characteristics (e.g. geometrics, travel, etc) statewide. State Highway System locations that have a statistically significant collision concentration are flagged for investigation. The quarterly output of the TASAS analysis is the Table C –Investigation Locations Report (Table C).
2006 Annual 5 Percent Report Location Identification
top
For the purpose of the 2006 Annual 5 Percent Report, Caltrans used State Highway
System location information from the Table C report for the second quarter of
2005. The second quarter Table C report provided location information for the
36 month period spanning July 1, 2002 through June 30, 2005. The Table C report
identified 2,624 locations for potential investigation. Five percent of the
identified locations requires Caltrans to identify not less than 131 locations.
Caltrans split the total locations by location type (intersections, ramps, and
roadway segments) and sorted by fatal and injury7
collision rates from high to low. Finally Caltrans selected the top 5 percent
of State Highway System locations for each location type for inclusion in the
2006 Annual 5 Percent Report (85 roadway locations, 25 intersection locations,
and 23 ramp locations). The results are contained in Appendix A – 5 Percent
Report of Roadway Locations (State Highway System Only), Appendix B –
5 Percent Report of Intersections (State Highway System Only), and Appendix
C – 5 Percent Report of Ramps (State Highway System Only).
Strengths and Limitations of the 2006 Annual 5 Percent Report Approach
top
The strength of this approach is:
- Table C is a well established and proven methodology that has been used for decades to identify State Highway System locations for safety investigations, to implement safety projects, and successfully achieve reductions in fatalities and injuries on the State Highway System.
Limitations of the 2006 Annual 5 Percent Report Approach
The limitations of this approach include:
- The 2006 Annual 5 Percent Report does not include locations from city and county roadways. The 2007 and subsequent Annual 5 Percent Reports will include city and county roadway locations.
- The 2006 Annual 5 Percent Report identifies State Highway System locations using a rate-based analysis versus a count-based analysis and there is an inherent trade-off between them. Rate-based location identification tends to include lower volume, rural locations whereas count-based location identification tends to include higher volume, urban locations.
- The TASAS Table C methodology based on 0.2 mile segments may overlook longer corridor locations that also have safety needs.
VI. Remedies, Impediments to Implementation, and Cost
top
Figure 1 graphically shows how the roadway, the driver, and the vehicle all
contribute to fatal and severe injury collisions. The potential remedies which
could be applied to the State Highway System locations identified in this report
should look at implementing engineering, educational, enforcement, and emergency
medical services (4Es) countermeasures and strategies. Appendix D lists remedies
to reduce fatalities and impediments to implementation currently recommended
in California’s Strategic Highway Safety Plan (SHSP). California has assembled
a team to guide the implementation of the SHSP recommendations.
As Caltrans reported in the Highway Safety Improvement Program Annual Report to the FHWA for Fiscal Year 2005/06, California awarded more than $184 million of state and federal money to safety projects in the areas of intersection improvements, roadway/structure improvements, roadside improvements, signs, beacons, lane monitoring systems, rumble strips, and barriers.
As the California Office of Traffic Safety (OTS) reported to the FHWA in the
Highway Safety Plan for Federal Fiscal Year 2006, California’s planned
fund distribution for all active grants totaled more than $90 million for the
following program areas: alcohol and other drugs, emergency medical services,
community based organizations, occupant protection, pedestrian and bicycle safety,
police traffic services, roadway safety, and traffic records.
VII. Next Steps for the 2007Annual 5 Percent Report
top
California intends to employ the following steps to improve future versions
of the Annual 5 Percent Report:
- Establish a statewide safety stakeholder team to develop a methodology, which reports locations with safety needs for the local (city and county) roadways system as well as the State Highway System. The inclusion of city and county roads may necessitate a change in the methodology used to identify locations for subsequent Annual 5 Percent Reports.
- Review the SHSP Implementation Plan and utilize the 16 Challenge Area Action Plans to improve locations with safety needs in California.
VIII. Discovery and Admission into Evidence
top
Section 148(g)(4) stipulates that the "5 Percent Report" and any reports,
surveys, lists, schedules or data compiled or collected for any purpose directly
related to paragraph (1) or subsection (c)(1)(D) in the preparation of the “5
Percent Report”, or related reports published or made available to the
public by USDOT, “…shall not be subject to discovery or admitted
into evidence in a federal or State court proceeding or considered for other
purposes in an action for damages arising from any occurrence at a location
identified or addressed in such reports…” The information is also
protected by Section 409 of Title 23 USC (discovery and admission as evidence
of certain reports and surveys).
Appendix A – 5 Percent Report of Roadway Locations (State Highway
System Only) top
Summary
The table in Appendix A displays information for 85 roadway locations on the
State Highway System from 27 different counties in California. The 85 roadway
locations represent 5 percent of all roadway locations identified by the TASAS
Table C process discussed in the body of the 2006 Annual 5 Percent Report. The
roadway locations are sorted alphabetically by county, ascending by route, and
ascending by postmile.
How to Read the Table
The locations in this table are sorted alphabetically by county.
The table displays location information in the following columns:
- Route = State Route in California
- County = The California county in which the location.
- Postmile = For the State Highway System, California uses a postmile marker system for location identification. Beginning with each county’s boundary, every roadway on the State Highway System starts at mile zero (0) and increases moving South to North and West to East.
