Travel mode definitions #14

Closed gotom22 closed 4 years ago

Relates to all aspects of

I assign to folks with good sense for local travel surveys. For starters I suggest to paste mode definitions below.

Should include ICD-10 injury codes, and generally used definitions in crash data registries.

ICD-10 code have two classifications of modes, long and short. Long is used for victim, and short for cause of the injury (striking vehicle in ITHIM terminology).

Long version (ICD have fatalities for these categories):

More details on these groups in this file (Google drive): https://drive.google.com/open?id=1-pSHse3Vl2gNQ9YI37rj_kIBEJi8pmn6JVuaZtMe7-Q

The short version is the striking vehicle side. For example, for Pedestrian these are:

Aggregating long one to short ones should be doable. Main challenge is railway vehicle (short version), which isn't included in long version as own category. This will likely include e.g. metro and trams.

In Global Burden of Disease 2016 data transport injuries are provided for following modes: Pedestrian road injuries Cyclist road injuries Motorcyclist road injuries Motor vehicle road injuries Other road injuries Other transport injuries

ICD codes used in GBD classification are following:

Mode ICD10 ICD9
Road injuries V01-V04.9, V06-V80.9, V82-V82.9, V87.2-V87.3  
Pedestrian road injuries V01-V04.9, V06-V09.9  
Cyclist road injuries V10-V19.9  
Motorcyclist road injuries V20-V29.9  
Motor vehicle road injuries V30-V79.9, V87.2-V87.3  
Other road injuries V80-V80.9, V82-V82.9  
Other transport injuries V00-V00.8, V05-V05.9, V81-V81.9, V83-V86.9, V88.2-V88.3, V90-V98.8 E800-E807, E830-E838, E840-E849

robj411 commented 6 years ago

The complete list for the injuries module, following the ICD10 codes, is:

pedestrian cyclist motorcycle driver three-wheeler driver car driver van driver bus driver hgv driver motorcycle passenger three-wheeler passenger car passenger van passenger bus passenger hgv passenger

A good list is:

pedestrian cyclist motorcycle driver three-wheeler driver car driver van driver motorcycle passenger three-wheeler passenger car passenger bus passenger

Where we are not interested in details of the striking vehicle, and we use vehicle data to define striker exposure, we need only:

pedestrian cyclist motorcycle three-wheeler car van bus hgv

robj411 commented 5 years ago

For Accra, we define minimum five modes from the travel survey: car taxi walking bus bicycle

And can include in addition: motorcycle bus_driver truck walk_to_bus

We map them onto other types where necessary, mostly by pre-processing in order that the naming convention is consistent across modules. In fact, all these words have been hard-coded into ITHIM-R somewhere*, so perhaps it is a list we can build on, adaptively mapping modes if necessary further down the line.

*E.g.: (1) Each mode has a specified speed, emission factor, and distance relative to car. (2) Some modes have a ventilation rate and/or pollution exposure. (3) Currently 'walking' maps directly onto 'pedestrian' in the injury module.

robj411 commented 4 years ago

Travel modes are defined on a per-city basis. For the modules to work together, the speeds, emission inventory, trips, and injuries should match in terms of the words (inc spelling) used to describe the modes.

There are a few requirements, e.g. 'walking' mapping to 'pedestrian'. There are a few harmonisation steps where e.g. 'cycle' becomes 'bicycle'. This could be extended with a dictionary.

Modes are grouped in prespecified ways for injury distances, based on the cities we have worked with so far (and the ICD10 codes). See https://github.com/ITHIM/ITHIM-R/blob/master/R/add_distance_columns.R and https://github.com/ITHIM/ITHIM-R/blob/master/R/distances_for_injury_function.R.
