About the Rankings
Travel times by auto are calculated using a detailed road network and speed data that reflect typical conditions for an 8 a.m. Wednesday morning departure. Additionally, the accessibility results for each location at 8 a.m. are compared with results across the 24-hour period to estimate the impact of road and highway congestion on job accessibility.
Key factors affecting the rankings for any metro area include the number of jobs available and where they are located, the road network structure, traffic management practices, the provision of alternate transportation modes, and population size, density, and location. Better coordination of transportation systems with the location of jobs and housing (“land use”) will improve job accessibility by auto.
