Highway Capacity Analysis Training Highway Capacity Manual (HCM 2010) Highway Capacity Software (HCS 2010) This course includes lectures, software demonstrations and application examples on the Highway Capacity. Highway Capacity Manual (HCM 2010) procedures and use of the Highway Capacity Software (HCS 2010) for the operational analysis of intersections. The procedures are.
Welcome to the online edition of the Highway Capacity Manual. The (TRB) fifth edition of the (HCM 2010), incorporates results from more than $5 million of research completed since the publication of the HCM2000.
This latest edition significantly updates the methodologies that engineers and planners use to assess the traffic and environmental effects of highway projects. HCM 2010 introduces several firsts, including:. An integrated multimodal approach to the analysis and evaluation of urban streets from the points of view of automobile drivers, transit passengers, bicyclists, and pedestrians;. Guidance on the proper application of microsimulation analysis and the evaluation of those results;. The presentation of active traffic management in relation to demand and capacity; and.
Generalized service volume tables to assist planners in sizing roadway facilities. The TRB Highway Capacity and Quality of Service Committee invites users of the manual who are interested in improving the profession?s understanding of highway capacity and quality of service analysis to participate in the committee deliberations and to provide feedback about the HCM2010 methods. The committee website, www.AHB40.org, will be available for these interactions. How to Use this Site Before you get started, set up an account by clicking Sign Up above.

RE: Merge Analysis - with lane addition was posted on April 7th, 2016 at 5:04 PM EDT This situation was clarified in January 2013 (see below) to analyze the segments before and after the on-ramp as basic freeway segments, then check the capacity of the on-ramp using Exhibit 13-10. Page 13-22 (Clarification, approved January 2013): Add the following new subsection following the first paragraph of the “Special Cases” section: Single-Lane Ramp Additions and Lane Drops On-ramps and off-ramps do not always include merge and diverge elements. In some cases, there are lane additions at on-ramps or lane drops at off-ramps. Analysis of single-lane additions and lane drops is relatively straightforward. The freeway segment downstream of the on-ramp or upstream of the off-ramp is simply considered to be a basic freeway segment with an additional lane. The procedures in Chapter 11 should be applied in this case.
RE: Merge Analysis - with lane addition was posted on April 7th, 2016 at 5:20 PM EDT Thank you! We have another situation where the freeway segment is 3 lanes in EB direction before merge and at the merge point, the ramp is a 2-lane on-ramp with the outside ramp lane merges as shared freeway/ramp and inside ramp lane is a lane addition that continues for more than 1 mile. Would you use the HCS 2010 software for this or apply the merge equations from HCM 2010? If HCS software, what would you assume for number of freeway lanes – 3 or 4? And what would you assume for the number of ramp lanes? If using equations then which one in the manual? This situation is a major merge but in reality the on-ramp is not a major roadway.
So I am not sure if we can consider it as a major merge. Please advise on what methodology should be applied in this case. Thanks again, Vijit Self.
RE: Merge Analysis - with lane addition was posted on April 19th, 2016 at 7:10 AM EDT I have usually used the 2 lane ramp methodology for this. Please take number of lanes N as 3 and assume that the both your ramps lanes will merge back onto the freeway. And keep the length of La1=500ft, La2 =500ft to keep the effective length down to 1500 ft. The density estimated will be on the conservative side as you have assumed the outer lane, merges back rather than continuing as a lane addition. Trust this helps. To add a reply.
