Development & Application Of The Transportation Index For Sustainable Places (Tisp), Jason Zheng

Master's Theses

The purpose of transportation systems go beyond the movement of people and goods. These systems shape the natural and built environment which subsequently affects social and economic interactions. However, conventional metrics typically only address the mobility aspect of transportation via measures such as level of service and congestion. Metrics are needed to evaluate the broader impacts of transportation.

This work describes the Transportation Index for Sustainable Places (TISP), a performance metric designed to assess the sustainability of transportation systems with respect to environmental, social, and economic outcomes. The development of the TISP was guided through literature review focused on understanding …

The Impacts Of Road Capacity Removal, Jason E. Billings

Master's Theses

The road infrastructure of North America is aging, and many governments are faced with a critical decision: do we repair or remove freeways from our urban centers? Freeway repair is exceptionally expensive, but removing a freeway is widely seen as a risky venture which may result in negative traffic effects. Therefore, it is necessary to gain a clearer understanding of how removing road capacity effects traffic distribution. Three freeway segments were ultimately selected for case study analysis: two in San Francisco and one in Milwaukee. This analysis consisted of identifying changes in the traffic volumes and volume-capacity (V/C) ratios in …
