Predictive Method Analysis Used at Public Meeting

Postby chris.milner » Wed Mar 02, 2011 4:35 pm

We used the Predictive Method to perform a safety analysis of three alternatives (Existing/No Build and Two Alternative Design Configurations) on a Safety Improvement Project in New River Road, Arizona. The information has been valuable to the project team as it provides a quantitative safety analysis of the top three alternatives. It's also been useful in communicating the predicted crash rates for each alternative to the public.

Chris,

Are there any materials (PowerPoint presentations, project websites, etc.) that are publicly available - or that could be made available - which document how HSM methods were used on your project? That would be very helpful to others who are trying to implement such methods.

Also, were any software tools used to perform the safety analysis?

Mike,
I've been unable to figure out how to attach my presentation to the forum so I've posted it to our ftp site. This is from the Arizona ITE/IMSA Conference a few weeks back.

I used HiSafe software to perform the initial analysis and then input the project into Interactive Highway Safety Design Model (IHSDM) for cross-referencing the results.

The presentation link is here:
ftp://hsmuser:arizona@ftp.kimley-horn.com/_secure/hsmforum/AZ-Application-hsmforum.pdf

If the link does not work, directions for access to the ftp site are listed below:

The ftp folder has been created under the /_secure folder on the ftp://ftp.kimley-horn.com site.
Folder name : hsmforum
Username : hsmuser
Password : arizona
Expiration Date : 12/30/2011


Every browser handles secure ftp sites differently. The universal method to access the site from different browsers is the link listed below which includes the folder and site names as well as the user name and password:

ftp://hsmuser:arizona@ftp.kimley-horn.c ... e/hsmforum
Access to FTP
There are multiple ways to gain access to the FTP site.
Internet Explorer 7
IE 7 has implemented changes to browser FTP behavior. Follow the steps below to open the FTP site in IE 7.
1. Click the FTP link.
2. Once the FTP site is open in IE 7, click the Page icon in IE 7. This is located on the right just below the search box.
3. Select Open FTP Site in Windows Explorer.
4. You will get an error message stating that you don't have access. Click OK.
5. Click File in the top menu.
6. Select Login As... .
7. Enter the username and password for the folder you are accessing and click OK.
You should now have access to the FTP site.
Copy/Paste Method
FTP can be handled by Windows' file explorer called Windows Explorer. Simply copy the link from this e-mail, open Windows Explorer, and paste the link into the address bar. This will open the FTP site and grant you access.
Link to FTP Site
Once you are able to access the site, a third way to connect becomes available. Included in the root directory of the FTP site is a command file. You can download this file to your local machine and use it as a direct link to the FTP site. Simply download the 'FTP Link - hsmforum.cmd' file and place it somewhere you can easily find it, such as your desktop. Once you have it downloaded you can use this to connect to the FTP. Double-click the file and it will open Windows Explorer and prompt you for your username and password. Enter these and press Login and you will be in the FTP site.

Chris,

I was able to access the presentation directly from the link you posted. Thank you!

This is an excellent application of HSM Part C methodology. The TRB Operational Effects of Geometrics Committee and the Highway Safety Performance Committee are seeking case studies of HSM applications for presentation at the TRB Annual Meeting in Washington, D.C. in January 2012, as part of a session on "Case Studies in Performance Based Analysis/Design." I'd be glad to follow-up with additional information if you are interested in presenting your application.
