Model estimation files for: G.D. Erhardt, S. Roy, D. Cooper, B. Sana, M. Chen, J. Castiglione "Do Transportation Network Companies Decrease or Increase Congestion?" (2018) Please feel to email greg.erhardt@uky.edu to obtain more information about this dataset. There are two files in the same format: ESTFILE_2010.csv - reflecting year 2010 conditions ESTFILE_2016.csv - reflecting year 2016 conditions Each file has one record for each ModifiedTMC and TOD, with the records matched between the two years. The columns are as follows: ID - a unique ID, which is a combination of the next two fields ModifiedTMC - ID for the spatial unit of analysis, a directional section of roadway TOD - Time-of-day: AM=6-9 AM, MD=9 AM-3:30 PM, PM=3:30-6:30 PM, EV=6:30 PM-3:00 AM, EA=3-6 AM YEAR - The year, either 2010 or 2016 CHAMP_LINK_COUNT - The number of SF-CHAMP links that aggregate to this ModifiedTMC PRESIDIO - Binary flag indicating whether the ModifiedTMC is on the Presidio Parkway or Veterans Blvd PHF - Peak Hour Factor, the share of the total period volume that occurs in the highest 1-hour period ALPHA - alpha term for use in VDF BETA - beta term for use in VDF AT - Area Type: 0=Regional Core, 1=Central Business Distritc, 2=Urban Business, 3=Urban FT2 - Facility Type: 1-Freeway, Expressway or Ramp, 2=Major Arterial, 3=Minor Arterial, 4=Local or Collector LANES - Number of lanes (can be non-integer due to averaging across SF-CHAMP links) DISTANCE - distance in miles CAPACITY - capacity in vehicles for the period as a whole FFS - free flow speed INRIX_SPEED - average speed, as measured by INRIX data SPEED_20TH - 20th percentile speed, as measured by INRIX data FF_TIME - free flow travel time INRIX_TIME - average travel time, as measured by INRIX data INRIX_VOL - implied volume CHAMP_PCE - SF-CHAMP passenger car equivalents (PCEs) CHAMP_VOL - SF-CHAMP volume (vehicles) TNC_VOL - TNC volume TNC_PUDO - TNC pick-ups and drop-offs AVG_DUR - TNC average duration variable, calculated as: (CAPACITY/LANES) * (TNC_PUDO / (3600/PHF])) AVG_DUR_MAJOR_ARTERIALS - TNC average duration variable on major arterials, zero elsewhere AVG_DUR_MINOR_ARTERIALS - TNC average duration variable on minor arterials, zero elsewhere BASE_INRIX_VOL_PRESIDIO - In 2016, the base year (2010) implied volume on the Presidio Parkway or Veterans Blvd, zero elsewhere. In 2010, zero everywhere.
