Evaluation of Automated Vehicle Technology for Transit

(Center Identification Number: 77975-00) The purpose of this report is to provide an overview of the state of automated vehicle (AV) technology in transit. The Florida Department of Transportation (FDOT) wishes to know what AV technology is currently available that could be used in transit with an eye towards possible demonstration projects. It finds that the operational use of AV technology by transit in the U.S. has been limited to a few prototypes. With one exception, there are no immediate plans by bus manufacturers to add AV technology to their vehicles. The exception was Volvo/Nova Bus. They are considering adding a bicycle/pedestrian warning system to their buses. It appears that for the moment any new demonstrations of AV technology in transit would involve significant engineering work and retrofitting of buses. Download the … Read entire article »

Estimating Costs and Benefits of Emissions Reduction Strategies for Transit by Extending the TRIMMS Model

(Center Identification Number: 77932) This study details the development of a series of improvements to the Trip Reduction Impacts of Mobility Management Strategies (TRIMMS™) model. TRIMMS now estimates a wider range of emission pollutants and incorporates a new module that evaluates the impact of land use strategies on transit patronage. TRIMMS uses the emission inventory of the Environmental Protection Agency Motor Vehicle Emission Simulator (MOVES2010a), which makes it suitable to run official State implementation air quality plan (SIP) and regional emissions analyses for transportation conformity purposes. This model enables the Florida Department of Transportation (FDOT), transit agencies, Metropolitan Planning Organizations (MPO) and local communities to conduct cost‐benefit assessments for most of the strategies identified in the FDOT‐sponsored Transit Ozone‐Reduction Strategies Toolbox, without the cost and expertise required by more sophisticated models.

Evaluation of Camera-Based Systems to Reduce Transit Bus Side Collisions-Phase II

(Center Identification Number: 77940) The sideview camera system has been shown to eliminate blind zones by providing a view to the driver in real time. In order to provide the best integration of these systems, an integrated camera-mirror system (hybrid system) was developed and tested. Traditional aftermarket systems utilize wide-angle cameras, which provide up to 100-degree horizontal field of view. The developed camera system had 65-degree horizontal view, which was adequate to cover the side blind zones. The initial system was tested in a controlled driving test with 29 drivers. The drivers used the system to drive the bus and identify objects placed around the bus. Comparison was performed with the mirrors only vs. the hybrid system. Statistical analysis showed that with the camera system, drivers had a 96-98 percent correct … Read entire article »

Evaluating the State of Mobility Management and Human Service Transportation Coordination

(Center Identification Number: 77060-NCTR-NDSU05) The Federal Transit Administration and its partners have worked to build a transportation coordination infrastructure to improve community mobility. Recent efforts at coordinating human services transportation have focused on mobility management, emphasizing the needs of customers and using the assets of a number of organizations. As a part of this study, an evaluation method was developed that can be used in communities across the country to examine the effectiveness of their mobility management and coordination programs. Results examine three key impacts: the impacts of services on meeting the needs of transportation-disadvantaged populations, the impacts of improved mobility on quality of life, and the impacts of mobility management and coordination efforts on meeting the goals of quality of service, ease of access, and efficiency. The evaluation method developed … Read entire article »

Improving Veteran Mobility in Small Urban & Rural Areas

(Center Identification Number: 77060-NCTR-NDSU02) The need for veteran transportation is growing rapidly because of the increasing number of older veterans as well as the numerous injured service men and women returning from Iraq and Afghanistan. Currently, for every fatality in Iraq, there are 16 wounded or injured soldiers. This represents an injury rate five times greater than during the Vietnam War. Thirty percent of veterans live in rural areas that often present transportation challenges. Many veterans in rural areas must travel extremely long distances to receive medical care, and veterans living in rural areas are reported to be in poorer health than veterans living in urban areas. The objective of this study was to identify veterans with mobility needs currently living in rural Minnesota, Montana, and North Dakota, and to quantify the … Read entire article »
