Colorado
Transportation Profile provides a series of reports highlighting major
federal databases and other national sources related to Colorado's infrastructure,
safety, freight movement and passenger travel, vehicles, economy and finance,
and energy and the environment.
Commodity Flow Survey
1997 "This survey produces data on the movement of goods in the United
States. The data from the CFS are used by public policy analysts and for transportation
planning and decision-making to assess the demand for transportation facilities
and services, energy use, and safety risk and environmental concerns." Individual
reports for each state and a U.S. summary show data on the movement of goods
by value, weight, average miles per shipment, mode of transportation and type
of commodity shipped.
Fatality Analysis Reporting
System (FARS) provides online access to data on Fatal Crashes by Roadway
Function Class and Atmospheric Condition; Vehicles Involved by Rollover Occurrence;
Driver Reports, and Fatality Reports. The Driver and Fatality Reports include
a wide variety of data on blood alcohol content (BAC), motor vehicle violations,
use of restraints (seat belt), vehicle type (such as large truck, emergency
vehicles, etc.), time of day, pedestrian fatalities, fatalities in the beds
of pickups, train collisions, urban and rural roads, and other factors.
Accident--train accidents reported on form FRA F 6180-54.
Casualty--deaths or injuries to any person, or occupational illnesses
to railroad employees, regardless of the type of accident/incident.
Highway/Railway--any impact/collision between a rail and highway user
at a crossing site.
Operational data --train miles operated, employee hours worked, passengers
transported
Freight
Transportation by State, 1996 Choose Colorado from the list of states
for access to data on transportation facilities, commodity movements, rail
shipments, transportation establishments, truck registration and vehicle-miles
traveled, motor carrier, fatal truck crashes, rail accidents and fatalities,
and hazardous materials incidents. Available as a .pdf file.
2001 Urban Motility Study "provides
data on the performance of some elements of the transportation system in 68
urban areas through research performed in cooperation" with state transportation
agencies. Includes the full text of the national report and data for Boulder,
Colorado Springs and Denver from 1982-1999. The data include daily vehicle
miles traveled on freeways and principal arterial streets and the percent
of moderate, heavy, severe, and extreme congestion experienced on each. The
data include a measure of roadway system performance that includes an estimated
annual hours of delay, annual excess fuel consumed, and an annual congestion
cost.
Vehicle Inventory
and Use Survey (formerly Truck Inventory and Use Survey) provides 1992
and 1997 data on "physical characteristics [that] include date of
purchase, weight, number of axles, overall length, type of engine,and body
type. Operational characteristics data include type of use, lease characteristics,
operator classification, base of operation, gas mileage, annual and lifetime
miles driven, weeks operated, commodities hauled by type, and hazardous materials
carried. Less detailed physical characteristics data are collected for vans,
pickups, and sport-utility vehicles because they are relatively homogenous
in design and use."
