I watched the Institute of Transportation Engineer's webinar yesterday that covered an overview of the new HCM 2010. This is a huge change from the 2000 Highway Capacity Manual (explaining why the 2010 HCM is coming out in April 2011.....). Here are the slides from the webinar (Download HCMoverview).
Here are some of the highlights from the webinar:
- HCM 2010 is supposed to ship this week.
- ITE will have ten webinars to go over individual components of HCM 2010 (more info here)
- The three hard copy volumes total 1200 pages
- New elements
- Multi-modal approach (ways to analyze bikes, peds, transit in addition to vehicles)
- Chapter describing when/how to use advanced traffic analysis tools such as micro-simulation
- Refined Level of Service criteria based on current research
- Primer for non-technical audiences
- Analysis accounts for actuated controllers and left turn lane queueing at traffic signals
- Tools for analyzing roundabouts (this is probably my favorite update - we finally have a simple apples to apples way of comparing stop signs/signals/roundabouts)
- All way stop signs - include three approach lanes instead of just two
- Side street stop signs - considers traffic from adjacent intersections
- Quick estimation method for interchange ramp terminals
- Volume 4 is an online site that contains discussion boards/errata/additions. Tools to make this more of a living document.
I plan to attend about half of the upcoming HCM 2010 webinars (assuming NCITE continues to host them for a $10 fee). I'll post a summary for each webinar I've attended. I'll also post some thoughts on the HCM once I have a chance to go through my copy. I'm also considering posting my login/password for Volume 4 so all of my loyal readers can log onto the website (without having to buy the $275 book). Stay tuned...
