RESEARCH: Green Design

A study of automobile air emission costs published last December in the Transportation Research Record has been receiving a fair amount of media attention. CEE graduate student, Yeganeh Mashayekh's study, Costs of Automobile Air Emissions in U.S. Metropolitan Areas, found the total air emission costs and external environmental cost of automobile air emissions in 86 metropolitan areas of the US is estimated to be $145 million a day. Los Angeles, CA and New York City, NY are on the top of the list each contributing $23 million/day to the estimated external environmental cost. Total air emission cost, solely due to traffic congestion for the same 86 U.S. metropolitan areas, was also estimated to be $24 million per day.

Mashayekh co-authored the paper with Paulino Jaramillo (EPP), Mikhail Chester (ASU), Chris Hendrickson (CEE), Chris Weber (STPI).  As part of the Green Design research group, Mashayekh is a dual degree, doctoral candidate in CEE and EPP and is advised by Professor Chris Hendrickson.
