Roadway Geometric Design for Improved Safety and Operations

• Offered for free to Central Ohio Section ASCE Members
• Seating is limited to the first 25 people
• Bring your own lunch

Purpose and Background
This webinar explores the National Cooperative Highway Research Program (NCHRP) Synthesis 432: Recent Roadway Geometric Design Research for Improved Safety and Operations as well as other recent publications such as NCHRP Report 707 on Auxiliary Lanes, NCHRP Report 730 on Ramp Terminals and NCHRP Report 422 on Trade-Off Considerations in Highway Geometric Design. Given the abundance of literature on roadway geometric design issues, practitioners have faced challenges identifying the information that they need to do their job effectively.

The webinar, like the Report 432, provides options to practitioners on where to find these sources to help them make more informed decisions on geometric design issues that impact safety and operations. NCHRP Synthesis 432 is an update to NCHRP Synthesis 299 that was published in 2001. The report is structured to correspond to chapters in the American Association of State Highway and Transportation Officials Policy on Geometric Design of Highways and Streets, more commonly referred to as the Green Book. Reports 707, 730 and 422 were published in 2011/2012 and provide additional guidance that practitioners find useful.

The webinar reviews NCHRP Synthesis 432 material in other related NCHRP reports on a topic by topic basis, highlighting key findings and important topics of geometric design research throughout the previous decade.

RSVP to newsletter@centralohioasce.com by Monday, September 14, 2015.

Intended Audience
This webinar benefits transportation professionals (engineers and planners) who work for consultants, cities, counties, and state agencies involved in designing highway projects. This course is designed for individuals with some background or training in designing highways including intersections and interchanges.

The Central Ohio Section of ASCE sponsors free continuing education webinars as a service to our members. These webinars are produced by ASCE and normally cost $250 or $300 for ASCE members. However, the Central Ohio Section is paying the registration fee and inviting any interested section members to attend for free. Just RSVP by the deadline. Seating is limited, so do not delay.

You can see the complete list of webinars available from ASCE National on their website. If you see one you like, let us know. If you and your company would like to host one, let us know that too. If you open it up to any interested Central Ohio ASCE section members to come, we will pay the registration fee.
