Enhancing Capacity And Managing Demand To Increase Short-Term Throughput On The San Francisco-Oakland Bay Bridge, Kevin Reid Carstens Dec 2016

Enhancing Capacity And Managing Demand To Increase Short-Term Throughput On The San Francisco-Oakland Bay Bridge, Kevin Reid Carstens

Master's Theses and Project Reports

While there are many proposals for fixing congestion between San Francisco and Oakland in California by adding a new bridge or tube, these solutions will take decades to implement even though a solution is needed now. This thesis assesses sixteen different strategies for reducing congestion in the short-term in the four categories of improving transit, promoting carpooling, implementing intelligent transportation systems practices, and incentivizing alternatives to using the Bay Bridge. Top priorities include HOV improvements on the West Grand Avenue and Powell Street onramps, altering WestCAT Lynx and BART transit services, partnering with rideshare apps to increase transit station accessibility ...


Tunnel Road Safety: A Look At Older Drivers’ Performance And Sight Impairment, Edith Lopez Mar 2014

Tunnel Road Safety: A Look At Older Drivers’ Performance And Sight Impairment, Edith Lopez

Master's Theses and Project Reports

In California, there is an observed trend in which collisions cluster in and around tunnels. The break in road continuity created by the tunnels disturbs traffic flow that can lead to collisions. One of the main contrasts between open roads and tunnel roads occurs in lighting. Drivers with sight deficiencies are unable to adapt their sight to the change in the lighting environment and may crash due to misperception of road alignment, vehicle’s speed and other physiological reactions, such as tension. The suspect population group of crashes occurring under the influence of tunnels conditions is older drivers.

The Effect Of Transit-Oriented Development On Vehicle Miles Traveled: A Comparison Of A Tod Versus A Non-Tod Neighborhood In Carlsbad, Ca, Natalie Louise Stiffler Jun 2011

The Effect Of Transit-Oriented Development On Vehicle Miles Traveled: A Comparison Of A Tod Versus A Non-Tod Neighborhood In Carlsbad, Ca, Natalie Louise Stiffler

Master's Theses and Project Reports

Transit-oriented development (TOD) is a strategy being used to reduce congestion, provide mode choice, and improve quality of life. A large amount of research has been done on individual aspects of TOD, but research specific to transportation-related benefits of TOD is limited. There is a need for traffic and transit data that is supported by comprehensive resident, employee, and user surveys to demonstrate the interrelationship between land uses, transportation, and socioeconomic and demographic characteristics. Moreover, VMT data at the household level is essential to analyze household travel behavior and the potential for VMT related emissions reduction.
