  Citation × Citation Citation Abstract Copy Title: Self-Organizing Signals: A Better Framework for Transit Signal Priority Author: Furth, Peter G. Year: 2015 Actuated traffic signal control logic has many advantages because of its responsiveness to traffic demands, short cycles, effective use of capacity leading to and recovering from oversaturation, and amenability to aggressive transit priority. Its main drawback has been its inability to provide good progression along arterials. However, the traditional way of providing progression along arterials, coordinated-actuated control with a common, fixed cycle length, has many drawbacks stemming from its long cycle lengths, inflexibility in recovering from priority interruptions, and ineffective use of capacity during periods of oversaturation. This research explores a new paradigm for traffic signal control, “self-organizing signals,” based on local actuated control but with some additional rules that create coordination mechanisms. The primary new rules proposed are for secondary extensions, in which the green may be held to serve an imminently arriving platoon, and dynamic coordination, in which small groups of closely spaced signals communicate with one another to cycle synchronously with the group’s critical intersection. Simulation tests in VISSIM performed on arterial corridors in Massachusetts and Arizona show overall delay reductions of up to 14% compared to an optimized coordinated-actuated scheme where there is no transit priority, and more than 30% in scenarios with temporary oversaturation. Tests also show that with self-organizing control, transit signal priority can be more effective than with coordinated-actuated control, reducing transit delay by about 60%, or 12 to 14 s per intersection with little impact on traffic delay.

  Citation × Citation Citation Abstract Copy Title: Financing Mechanisms for Capacity Improvements at Interchanges Author: Strathman, James G., Simmons, Elizabeth Year: 2010 This report examines the use of alternative local financing mechanisms for interchange and interchange area infrastructure improvements. The financing mechanisms covered include transportation impact fees, tax increment financing, value capture financing, local improvement districts, transportation corporations, state infrastructure banks, local option transportation taxes, fair share mitigation, and transportation concurrency. The financing alternatives are assessed in the context of Interchange Area Management Plans, which are required by the Oregon Transportation Commission, as well as in the context of the Oregon Department of Transportation’s responsibilities under the state’s Transportation Planning Rule.

  Citation × Citation Citation Abstract Copy Title: Transferring Community-based, Active Transportation GIS Assessment Tools Nationwide Author: Schlossberg, Marc, Larco, Nico Year: 2009 “Livability” has recently been declared one of four top priorities by the Secretary of the U.S. Department of Transportation (USDOT), and the USDOT, the Environmental Protection Agency (EPA), and the Department of Housing and Urban Development (HUD) have entered into an historic partnership to address the issue. Ultimately, this term refers to the quality of life within one’s community and the ease, comfort, and joy with which one can access places he or she want to go. For most Americans, their neighborhoods have been designed to predominantly accommodate the automobile, and more active forms of transportation such as walking and biking have been neglected. Previous and current OTREC work has developed a suite of GIS tools focused on assessing these environments in a fine-scaled, field-based, geo-referenced format so that local communities can better identify gaps in their networks and work to make appropriate improvements. This work explicitly focuses on the role and capacity of a general citizenry to conduct built environment active transportation audits and engage in facilitated discussions about the data and maps resulting from their community data collection.

  Citation × Citation Citation Abstract Copy Title: Cargo Cycles for Local and Last Mile Delivery: Lessons from New York City Author: Conway, Alison Year: 2015 Cities depend on safe and efficient goods movement to support community livability and a healthy economy. However, delivery of goods in an urban environment presents a tremendous challenge. Traditional motorized vehicles used for goods movement – ranging from cargo vans to box trucks - are inherently incompatible with (1) the multimodal street environments of modern cities, with clean, quiet conditions preferred by residents, and (2) larger environmental sustainability goals. As freight flows continue to grow with the demands of global trade, new urban freight and city logistics solutions are needed. Cargo cycles – human powered cycles equipped with freight carrying capacity – offer a potential alternative to reduce freight externalities. This presentation will discuss the results of the recently completed “Freight Tricycles in New York City (NYC)” project, which aimed to evaluate the potential for cargo cycles as a local and last-mile freight transportation mode and to understand the traffic performance and externalities of cargo cycles compared to motorized delivery modes in NYC conditions.
