via @nasemTRB New Mobility Options in Travel Demand Forecasting and Modeling: A Guide: Emerging transportation technologies and shared mobility services, or new mobility options (NMOs), are affecting travel behavior and demand. NMOs may include shared micromobility, transportation networking companies (TNCs), and connected and autonomous vehicles (CAVs). As NMOs grow in availability and use, transportation planners and decision-makers need to be able to understand how to… http://www.trb.org/Main/Blurbs/183257.aspx?utm_source=dlvr.it

Traffic Impact: Tolls Off Tolls On: Hi list subscribers
Last year I put out a call (on TMIP) for examples of roads, bridges or tunnels from around the world where road tolls had been activated - see below. We wanted to understand the impact on traffic using the facility.
We have completed our research and have prepared a first draft of our paper. Our preference is to avoid academic journals and publish in the 'grey literature'. Notwithstanding, we try to abide… https://tmip.zephyrtransport.org/scripts/wa-ZEPHYRTRANS.exe?A2=TMIP%3Bc848e9bc.2405&utm_source=dlvr.it #tmip

Re: Comparison of CTPP OD flows at different aggregation levels?: Krishnan and Ed are correct and on target. The 2012-2016 and forthcoming 2017-2021 CTPP do NOT include the “extended workplace allocation”. Previous packages (1990?, 2000, and 2006/2010) DID have extended workplace allocation.
Allocation is the Census Bureau term for missing value imputation.
“Standard Workplace Allocation” is Census-speak for “primary imputation”. This process imputes… https://tmip.zephyrtransport.org/scripts/wa-ZEPHYRTRANS.exe?A2=TMIP%3Bc7e301ab.2405&utm_source=dlvr.it #tmip

Re: Comparison of CTPP OD flows at different aggregation levels?: Or put another way--The difference between the small areas and county
totals is because the Census Bureau cannot (easily, my words) geocode
all of the work locations to the Tract, Block Group or Block (including
TAZ and TADs) but will code every work location to a county and state.
The difference between the TADs and TAZs is more likely due to the CTPP
special rounding rules and aggregating rounded… https://tmip.zephyrtransport.org/scripts/wa-ZEPHYRTRANS.exe?A2=TMIP%3Bffd37fea.2405&utm_source=dlvr.it #tmip

Re: Comparison of CTPP OD flows at different aggregation levels?: This is due to the workplace allocation issue in Census data. Standard
workplace allocation procedures at the Census Bureau imputes only at the
county and place level geographies & not below that. In previous iterations
of the ACS based CTPP, the Census Bureau did an extended workplace
allocation to overcome this difference but did not do so in the 2012-2016
CTPP. Details of how it was done for the… https://tmip.zephyrtransport.org/scripts/wa-ZEPHYRTRANS.exe?A2=TMIP%3Bd79144a5.2405&utm_source=dlvr.it #tmip

Comparison of CTPP OD flows at different aggregation levels?: We are looking at the CTPP flows in the Washington DC region and notice
that they are not the same depending on the level of aggregation (County to
County, TAZ to TAZ, TAD to TAD). I presume this is due to the fact that
some places can be assigned accurately at the county level but not the TAZ
level. Has anyone looked at whether the losses are distributed randomly or
if there are patterns, and how to… https://tmip.zephyrtransport.org/scripts/wa-ZEPHYRTRANS.exe?A2=TMIP%3Bd2807.2405&utm_source=dlvr.it #tmip

Re: Invitaiton to an International Symposium on "Integrated land use/transport models for carbon neutral strategies" at Osaka University, Japan: This looks like a great opportunity, Rolf! I wish I could attend, but I don't think I can get to Japan at that time. My M.Sc. thesis was an extension of PECAS to include an environmental/physical flows component. Unfortunately, it didn't reach implementation.

Re: A New VDF Formula: Thank you for bringing up the capacity constraints and various issues in the context of volume delay functions and static traffic assignment (STA)!

A New VDF Formula: A faster process for doing UE assignments has been the subject of several recent TMIP postings. A User Equilibrium (UE) assignment is of course a Nash Equilibrium in which the paths are chosen such that the impedance (e.g. Vehicle Hours of Travel) of every user between any OD pair is at equilibrium. The issue is that the impedance on each link is not known until after equilibrium is achieved. Because the impedance function uses the equilibrium… https://tmip.zephyrtransport.org/scripts/wa-ZEPHYRTRANS.exe?A2=TMIP%3B52f88010.2404&utm_source=dlvr.it #tmip
