Workshop 1: Freeway & Interchange Design: Applying the Science and Art of Engineering Innovation
8 hours – Sunday, 21 June afternoon and Monday, June 22 morning (note: this workshop is 8 hours, starting on Sunday afternoon and continuing on Monday morning)
Moderators: Mark Doctor, FHWA and Hermanus Steyn, Kittleson & Associates, Inc.
Transportation professionals around the globe are challenged to improve the safety and mobility of their urban freeway (motorway) network and the interchanges (junctions) within them. Freeway and interchange improvement projects are typically major investments that require balancing competing demands and working within severe constraints. This workshop will begin with a historical perspective of freeway and interchange design and examine the evolution of freeways with presentations on several common challenges encountered in the modern design of urban freeway and interchange improvement projects. Relevant examples and case studies from multiple countries will be used to help illustrate these issues and challenges, including the successful application of several innovative interchange designs. Workshop participants will then form breakout groups and discuss a case study to apply some of the important freeway and interchange design principles presented earlier in the workshop. Each group will discuss potential design strategies and applicable existing analysis tools, and identify research needs to address the gaps in current knowledge. The workshop will conclude with a common session during which participants will discuss the research needs with regard to tools, techniques, and methodologies to assist in meeting the challenges faced.
Workshop 2: Future Directions in Highway and Street Design and Analysis
4 hours - Sunday, 21 June afternoon
Moderator: R.J. Porter, University of Utah
Geometric design of highways and streets involves weighing and balancing a variety of considerations in the pursuit of a choice or a series of choices. Construction cost, durability, aesthetics, maintenance, operations, non-motorized user performance, traffic flow, and safety are some of the principal considerations. Meaningful evaluations and assessments of trade-offs requires that the consequences of design decisions be characterized and quantified. There is general agreement that design decisions should reflect the specific project circumstances and setting. Transportation agencies also deliberate on how to best utilize available resources. Agencies are continually assessing the “return on investment” that expenditures are likely to yield. To meet these needs, geometric design policies and practices, as well as tools used to predict the outcomes of geometric design alternatives, are constantly evolving, with an end goal of allowing agencies to make informed decisions on the probable trade-offs that are likely to result for specific circumstances. This workshop will cover emerging and future directions and trends in highway and street design and analysis, including performance-based geometric design; risk- and reliability-based analysis of design criteria and decisions; current capabilities and needed improvements in making predictions of the safety effects of design decisions; and the role of value engineering in geometric design. The format of the morning session will consist primarily of podium presentations, with significant opportunity for audience feedback and interaction with speakers following each presentation.
Workshop 3: A New System for the Interactive Design, Presentation and Charette Process for Roads
4 hours – Sunday, 21 June afternoon
Moderator: Wolfgang Kuehn, University of Applied Sciences, Zwickau
An all-round design process is increasingly necessary to cope with complex traffic construction projects in order to improve the design quality and increase traffic safety, assess private and public issues in a more objective manner and generally reduce the time needed for the approval of projects. In principle, this overall process needs to be made more transparent, clearer and more comprehensible for all those involved in order to be able to demonstrate the goal of the planning and building work in a better manner. Using a new kind of 3D design methodology, the design engineer can draw up various options for a road with three dimensions in real time during the first phase, check that it conforms to the guidelines and correct any errors. The workshop takes place in three parts. The overall complex system is presented using three brief lectures in the first part. Instructions are also provided to familiarize people with the “HighwayDesigner” software system. Groups work on a prepared practical example using the “HighwayDesigner” software system in part 2. This work can take place using a laptop, as the software is made available on a USB stick. Part 3 concerns the presentation of results and discussions on a large screen. At the same time, the results of the design work can also be assessed individually in a complex manner using a head-mounted display.
Workshop 4: World Road Association’s Road Safety Manual |Sponsored by ICBC
4 hrs - Sunday, 21 June afternoon
Sponsored by ICBC
Moderator: Michael Griffith, FHWA; Michael Tziotis, ARRB Group; Bruce Corben, Corben Consulting (Australia); and Jianbei Liu, CCCC First Highway Consultants Co Ltd (China)
The World Road Association (PIARC) will complete the development of a new Road Safety Manual in late 2014/early 2015. The RSM will assist policy makers, road safety infrastructure managers, and practitioners in advancing road safety on several levels. The focus is on road safety infrastructure with linkages to enforcement, education, and emergency medical systems. The Manual is centered on advancing the Safe System Approach which is based on an ethical position where it is never acceptable that people are seriously injured or killed on a country’s road network. It will highlight notable policy frameworks and technical practices as well as provide overall guidance on management of interventions to achieve results, relevant to all countries, regardless of their level of infrastructure development. This workshop will raise awareness of this Manual which will be a web-based resource. It will provide a: 1) a high-level overview of the Manual, 2) detailed overview of Part III which will contain the technical chapters, and 3) a discussion of noteworthy international geometric design policies and practices. The key material that will be covered from the Part III chapters will touch on:
- infrastructure safety management: policies, standards, and guidelines
- design concepts to achieve road user compliance and address unsafe behaviors
- assessment of potential risks and identification of issues
- intervention selection and prioritization
The primary audience of this workshop is professionals from lower and middle-income countries.
Workshop 5: The Future of the Highway Design Process
4 hrs - Monday, 22 June morning
Moderator: Timothy Neuman, CH2MHill
Timothy Neuman of CH2M HILL will facilitate a half-day workshop on the need for change and elements of such change in the highway design process. The workshop will include a briefing on findings from NCHRP Project 15-47, Developing an Improved Highway Geometric Design Process and other similar relevant research. Attendees will be provided a briefing summary in advance of the workshop. Three to five break-out sessions will be formed to discuss specific aspects of the research, including the following topics:
- Needs for alternative functional design models for core geometric elements such as horizontal alignment and sight distance; discussion of potential alternative models and formulation of research needs to support alternative model development
- Adaptation of Building Information Modeling (BIM) processes into geometric design criteria and practices
- Policy implications for highway agencies of the institutionalization of explicit safety performance-based criteria in geometric design
- Knowledge gaps in highway safety performance to be addressed for a revised process incorporating quantitative safety
Each break-out session will include a facilitator and recorder. Break-out leaders will report back to the workshop attendees for final question and answer period.
Workshop 6: Integrating Safety Diagnostics in the Project Development Process: Tools and Practices
4 hours – Monday, 22 June morning
Sponsored by ICBC
Moderators: John Milton, Mike Dimaiuta, Geni Behar and Alison Smiley
For transportation professionals around the world, determining and selecting the appropriate countermeasures to address highway safety needs is commonplace. The success of this selection relies on the ability to diagnose the contributing factors to crashes, select potential countermeasures and then determine the impacts of those countermeasures under differing site and design conditions. This workshop will provide the participant knowledge in the area of quantitative safety assessment beginning with project need, through project definition, and finishing with design decision-making. The workshop will present topics in a case study format and show how tools, such as SafetyAnalyst, Crash Modification Factor Clearinghouse, Highway Safety Manual, Human Factors Guide and the Interactive Highway Safety Design Model can be used. The workshop will show the practitioner a progression of network screening; diagnostic assessment of contributing factors to crashes; countermeasure selection (e.g., scoping of projects); and design decision making with predictive methods.
Workshop 7: Crash Modification Functions: International Transferability and Applications in Planning, Design, and Operations
4 hours - Monday, 22 June morning
Sponsored by ICBC
Moderator: Jennifer Ogle, Clemson University
For the last few decades, researchers around the globe have been working to develop standards for safety assessment through advancements in statistical methodologies as well as data collection and archiving. Crash modification functions (CMFs) provide a measure of safety effectiveness for a single road safety countermeasure or set of countermeasures, and have become widely used to assess potential safety outcomes of a treatment. This workshop will consist of two common sessions and a mid-workshop breakout session. The first common session will cover crash modification factors and their development, and will also include information on obtaining CMFs as well as identifying obstacles and opportunities related to transferring and applying them internationally. Several case studies covering multiple countries and continents will be used to show how CMFs are being applied in the project life-cycle from planning, through design, and into operations. The breakout session will allow small groups to explore various subsets of CMFs, and further discuss opportunities and obstacles faced by safety researchers and practitioners in the transfer and application of CMFs. Of particular interest for the discussion is the topic of transferability of CMFs, as this is a fundamental obstacle due to the variety of road infrastructure, operating characteristics, driver behaviors, and fleet mix found across international boundaries. The second common session will give groups a chance to report out findings from group discussions and define a path forward for research to address transferability challenges and training to encourage more widespread application of CMFs.
