COMPARISON OF DAYTIME AND NIGHTTIME POPULATION ADJACENT TO INTERSTATE HIGHWAYS IN METROPOLITAN AREAS USING LANDSCAN USA

An article of similar title was published in the International Journal of Radioactive Materials Transport in 1999. The study concluded that the daytime and nighttime populations are not substantially different for the metropolitan areas examined. This study revisits the issue, but using the LandScan USA high-resolution population distribution data, which includes daytime and nighttime population. Segments of Interstate highway beltways, along with the direct route through the city, for Atlanta, St. Louis, and Kansas City are examined with an 800 meter (800m) buffer from either side of the highways. Using the LandScan USA data the day/night ratio of population is higher than previously reported. LandScan USA daytime and nighttime data will be incorporated into the TRAGIS routing model in future.
