For the new ,kilometer National Highway System (NHS), consisting of the Interstate Highway System and principal arterials, nationwide design standards remained in effect. However, the new law eliminated the requirement for the use of nationwide design standards for non-NHS projects, such as those built under the Surface Transportation. Improving the design and operation of the transportation system in part may reduce crashes and fatalities among these vulnerable road users. For agencies to make effective safety improvements, they must understand what risk factors are associated with pedestrian-related crashes, where those risks exist on the transportation network, and what.

ANALYSIS OF DESIGN ATTRIBUTES AND CRASHES ON THE OREGON HIGHWAY SYSTEM James G. Strathman Kenneth J. Dueker Jihong Zhang Timothy Williams Center for Urban Studies College of Urban and Public Affairs Portland State University Portland, OR for Oregon Department of Transportation Research Unit Salem, OR June Cited by: Since the passage of the Highway Safety Act ofstate departments of transportation have engaged in systematic safety improvement planning and programming.
According to Davis (), the general approach to safety improvement planning employed by most states follows six principal steps: 1.

With approval of the Oregon Transportation Safety Action Plan, the Oregon Transportation Commission established its expectations regarding transportation safety. The Oregon Department of Transportation's Traffic-Roadway Section manages the highway engineering safety.
Vertical alignment, which includes vertical grades and lengths, is a critical aspect of highway design policy that influences safety. A full understanding of the effect of vertical grade and segment length on highway safety can help agencies to evaluate or adjust their design policies regarding vertical alignment design features (grade and length).
The Oregon Department of Transportation manages access to the state highway system based on: State law. Engineering principles. Objective standards. These guidelines are used to balance the economic development needs of property abutting the highway system, with the need to maintain safe and efficient operation of the system.
Highway Design Handbook for Older Drivers and Pedestrians. FOREWORD. The proportion of the population over age 65 is growing significantly. Older road users can be expected to have problems driving and as pedestrians, given the known changes in their perceptual, cognitive, and psychomotor performances, presenting many challenges to transportation engineers, who must ensure system.
This book provides in-depth information about road user characteristics and highway geometric design. It explains the collection and analysis of different types of traffic data, obtained as part. Introduction: It is widely agreed that highway work zones pose significant threats to road users because driving conditions in work zones are quite different from the normal ones, particularly when traffic volumes approach a highway capacity.
Therefore, work zone safety is a critical aspect for state agencies and traffic engineers. Method: In the current study, a total of 10, crashes that. This paper presents the results of an empirical analysis of screening and ranking for weather related crashes on rural km (1 mi) highway sections of Oregon highways.
The analysis includes data generated with the extensive use of spatial techniques and incorporates climate data to enhance environmental considerations. This is a crash tree analysis focusing on the county highway system in Minnesota. Analysis shows there are more severe crashes on the county system than the state system, and the majority of these crashes are rural, involve road departure, and occur on.

tracted from the Fatality Analysis Reporting System (FARS) show that the driver-level attribute “driving too fast for conditions or in excess of posted speed limit” is the critical contributing factor in more than 99 percent of all speeding-related fatal crashes, as de-fined by the National Highway.
This document is updated annually and includes data from forward. The tables allow data to be sorted or filtered at the county, district and state levels. Data are further broken down by population classification, route classification, highway system, functional classification, on-system route, and metropolitan planning organization.
With alm lane miles on the Oregon highway system, the Oregon Department of Transportation (ODOT) is responsible for managing and maintaining the roadway assets on the State-maintained roadway system. Managed assets include barriers, traffic signals, lighting, pavement markings, and signs.
These characteristics, also known as risk factors (For purposes of the Systemic Safety Project Selection Tool, the term "risk factor" refers to a common characteristic of the locations where severe crashes occurred; therefore, the presence of a risk factor at other locations is an indicator of the potential for a future severe crash.), can be.
To help alleviate this concern, Oregon DOT applied the predictive methods of the HSM (AASHTO ) and C H A P T E R 1 0 Case Example 2: Oregon Department of Transportation Key Takeaways â ¢ Complemented a hot spot analysis approach with a systemic analysis approach.
â ¢ Used a set of risk factors established by an expert panel and applied. Analysis Roadway Length Considerations The roadway network can be divided into spots and/or segments. Isolated curves, bridges, and intersections are examples of spot locations. Segments are typically defined by a particular length (e.g., feet, mile, mile, etc.) or as the section of highway between two defined spots.
