Bus Stops and Bus Users in the City of Detroit

I. Introduction

According to Detroit Area Study (DAS), public transportation use has been declining. 2001 DAS data shows that only 8.3 percent of commuters choose bus as their travel mode whereas 69.1 percents of people are driving alone. Furthermore, 63.1 percent of respondents answered that they never use bus while frequent users, including daily users and people taking a bus at least once a week, are about ten percent. (chart)

Previous studies indicate that there are relationships among environmental factors, psychological factors and transportation use (Bamberg, Sebastian and Peter Schmidt. "The impact of general attitude on decisions" Rationality and Society, Thousand Oaks, Feb 1999). GIS data collected in 2000 by SEMCOG enable to observe the condition of bus stops in Detroit, and the bus stop condition would be one of indicators that represent environmental condition of public transportation. Also, 2001 DAS shows specific preferences and attitudes toward transportation among Detroiters. Bus stop condition, Detroiters' inclination toward transportation and their travel behavior will be examined by using GIS.

II. Methods

First, the overall condition of bus stops was observed. Five indicators, including stop sign, light, shelter, bench, and sidewalk, are used to evaluate condition of bus stops. Each bus stop is scored 1 to 5 depending on existence of five indicators.
Second, characteristics of samples were observed. At this stage, geocoded respondents and bus stop data were combined.
Third, individual preferences and bus stop conditions were viewed together.
