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)! We would like to highlight that the primary goal of dynamic traffic assignment (DTA) is to lift the limitations of STA by incorporating time-dependent traffic flow variations. The concept of a "discontinuous BPR equation" can indeed offer significant benefits… https://tmip.zephyrtransport.org/scripts/wa-ZEPHYRTRANS.exe?A2=TMIP%3B30084294.2404&utm_source=dlvr.it #tmip

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

Invitation to an International Symposium on "Integrated land use/transport models for carbon neutral strategies" at Osaka University, Japan: While most sectors of the economy have massively reduced emissions, transport emissions have remained almost unchanged for 30 years.

Values of Time (road freight): Forums: Calls for papers

Hi

A revealed preference case study we examined recently suggested values of time (for commercial vehicles) that were higher that those typically recommended in official guidance. As a follow-up, we are compiling guidance on road freight values of time from around the world.

Our main focus is on N America, Chile, Europe, India, Australia and NZ. If you know of guidelines (eg. government guidelines) from… https://tmip.org/content/values-time-road-freight?utm_source=dlvr.it #tmip
