Transportation access for workers to jobs is important to the economic vitality of a region, as well as a social equity issue with regards to environmental justice populations. Considering resource scarcity and expanded cities, the prioritization of employment centers is an urban and transportation policy and planning challenge and this study offers a mathematical model to overcome these challenges.

Most research and databases present one-dimensional workforce information such as number of available workers, jobs, etc. in administrative or community jurisdictions such as villages, cities, states, etc. This study offers a novel approach for adding transportation measures as the second dimension to workforce information. Transportation agencies have traditionally used average travel times and travel time savings to measure system performance and benefits of their investments.

This study establishes the workforce information based on work commute time geographies rather than those political or administrative jurisdictions. The commute time during the morning peak period is the most important concern for workers and combining travel time measure with workforce information provides a powerful transportation planning tool.

The study also shows the region's Environmental Justice (EJ) areas transit accessibility to the regional job hubs by the number and percentage of EJ workers living in the commute sheds of the regional job hubs. The study discusses impacts of the increasing service frequencies for the existing routes of the NOACA transit system only. 

Finally, the study presents annual benefits of travel time and congestion savings for each percent of the worker-employer mismatch reduction and recommends a number of transportation and land use solutions to alleviate the overall strain to the transportation system that these mismatches cause.
