Abstract submission

Abstract submission is open now! Please submit your abstracts via this link.

We invite you to share your ideas on road design at the 6th International Symposium on Highway Geometric Design featuring the 6th Urban Streets Symposium.

Although we have already put together a very attractive and diverse program, there is room for new insights and ideas about our broad range of topics related to road design.

We would like to add new sessions with a focus on implementing, planning, designing and operating roundabout intersections in a urban street context and finding balance with other modes. We are also interested in topics related to designing streets post pandemic. For example: car-free streets, adding bicycle lanes, how to design for an increase in sustainable transport.

To encourage additional presentations on innovative road-related projects, we will consider abstracts on projects. The project needs to meet one or more of the suggested topics of the symposium (see topics suggestions further down on this page). Preference is that the project was opened for operations within the past 3 years; however, projects in the construction stage or before construction where the design is finalized will also be considered. Projects that used alternative selection and design tools are also appropriate.
A paper following the full requirements of the symposium is encouraged, but if a full paper is not appropriate for the subject matter, we will allow authors to provide a project brief as an alternative.
Similar to authors of papers, authors providing a project brief will submit a poster or slide presentation to be shared with attendees and other interested individuals. The project brief along with the presentation may be posted on our website. If the abstract is selected for presentation, the author will be notified of the appropriate format.
Minimum Requirements for a project brief:

  • Discussion, photographs, and/or illustrations that provides a comprehensive overview of the project that includes one or more of the following:
    • Highlights design challenges and how they were addressed and overcome.
    • Discusses the uses of new design criteria, guidelines, or design tools.
      • What was used and how they were incorporated into the design?
      • Did they work well?
      • Any issues or complications?
      • Any unexpected impacts to the design or design process?
      • How were challenges addressed?
      • How was the time or effort to perform the design impacted?
      • Any recommended changes or research related to the new design criteria, guidelines, or design tools?
    • Presents lessons learned including recommendations you would make to help other designers.
    • Listing of findings related to completed operation of the built facility compared to how the design intended the facility to operate.  Any surprises?  Any other findings?

We encourage authors to submit abstracts in any areas included in the wide spectrum of infrastructure design, including best practices.

Aim of the symposium

The symposium aims to encourage the knowledge transfer reflecting continuous improvement of highway and street geometric design and to provide the opportunity for international networking of highway and street design experts, from research and knowledge institutes, universities and higher education, major engineering consultants and highway contractors, and national, regional, and local road authorities.  Interactive workshops, encouraging a more active participation by all delegates, are aimed at sharing insights in thematic discussions, leading to valuable conclusions and recommendations for future designs.

Hosting the Urban Streets Symposium

In 2022 the International Symposium for Highway Geometric Design is featuring the Urban Streets Symposium (USS). For the first time USS will be a global symposium, hosted outside the USA. Besides topics on Highway Geometric Design, the 2022 symposium is open for Urban Streets topics as well.

All abstracts will be reviewed and considered for podium or poster presentations by the Steering Committee. Once an abstract is accepted, you will be invited to submit a draft paper. Finally, at least the presenting author must register for the symposium. Accepted abstracts will be confirmed by email to the corresponding author and will have an abstract reference number, to be quoted in all correspondence.

Papers submitted to the 2022 ISHGD Featuring the 6th USS are expected to be made available through electronic means such as a compendium on the ISHGD and/or USS websites, to facilitate information sharing and technology transfer. Although papers will be reviewed for presentation at the symposia, this review may not be as rigorous as that required of some professional journals, and so symposia papers are not considered to be formally published. Thus, authors may submit their papers to other professional and refereed journals for subsequent publication.

New for 2022! The one year postponement presents an opportunity to expand the focus on intersection design, including roundabouts. The Symposium will now include expanded tracks on intersection design, a workshop dedicated to intersection design and a related technical tour. The organizers are therefore encouraging authors to submit abstracts on a range of intersection design topics and projects. In particular, we would like to encourage the submittal of abstracts that include roundabouts. The following topics are of great interest: Intersection control evaluation that compares roundabouts and alternative intersections against traditional intersections for projects; accommodating pedestrians and cyclists at roundabouts and alternative intersections; addressing freight, railroad and transit demands and usage in the vicinity of roundabouts and alternative intersections; presentations on innovative projects that incorporate roundabouts and lessons learned; and the unique role of champions or leaders in the planning and design process. Please consider submitting your abstract for these or other related intersection topics.
