Tam, Robert
2000

This report summarizes PATH ATMIS research for fiscal year 1999/2000. In each of the brief project descriptions we state the objectives of the project and outline its status and some of its principal results. These descriptions are not intended to be comprehensive or complete, but rather to present a picture of the main thrusts of each of the reported projects. References are provided in the end of the report for more detailed information about particular projects. Taken together, the collection of project descriptions should give the reader an overview of the entire ATMIS research program...

On the Impacts of Bus Stops Near Signalized Intersections: Models of Car and Bus Delays

Gu, Weihua
Gayah, Vikash V.
Cassidy, Michael J.
Saade, Nathalie
2014

Models are formulated to predict the added vehicle and person delays that can occur when a bus stop is located a short distance upstream or downstream of a signalized intersection. Included in the set of models are those that predict the expected delays that cars collectively incur when a bus blocks one of multiple lanes while loading and unloading passengers at the stop. Others in this set predict the expected added delays incurred by the bus due to car queues. Each model is consistent with the kinematic wave theory of highway traffic, as is confirmed through a battery of tests. And each...

Development and Field Testing of An Interactive Transit Station Information System (ITSIS) Using Connected Vehicle Technologies

Meng, Huadong
Tsao, Jacob
Zhou, Kun
Picar, Justin
Mizuno, Bradley
Zhang, Wei-Bin
2018

The objective of Interactive Transit Station Information System (ITSIS) is to better inform transit travelers during their trips and to enable dynamic transit operations to better serve travelers. The ultimate goal is to make transit more friendly and attractive to the traveling population such that transit will become a viable choice for travel and an integrated part of the solution for congestion relief. This report documents a research effort to develop and test a ITSIS prototype that uses Connected Vehicle technologies to enable the real-time interaction between passengers and transit...

Creative Reallocation of Curbs, Streets, Sidewalks Accelerated by the Pandemic May Be Here to Stay

Shaheen, Susan, PhD
Cohen, Adam
Broader, Jacquelyn
2023

Curb space has been traditionally designed for private vehicle parking, public transit, and passenger and commercial loading. However, in recent years, a growing number of newservices and activities have increased the demand for limited curb space, including passenger pick-up and drop-off; last-mile delivery (e.g., courier network services, personal delivery devices); electric vehicle (EV) charging; micromobility parking and use (e.g., personally owned and shared bikes and scooters); and carsharing services. The curb serves a variety of functions such as vehicle and device storage (...

Bus Rapid Transit and the Use of AVL Technology: A Survey of Integrating Change

Gillen, David
Johnson, Doug
2002

AVL represents a radical change to many working in the public transit industry. When a new technology is introduced factor proportions change, responsibilities are altered and procedures change. There are threats to lines of authority, job security and responsibility. In all cases there are threats and the successful implementation of a new technology into any firm requires that it be managed, it will not happen automatically and ultimate success of the firm will be contingent on the implementation. The adoption of new technologies has always presented challenges for managers, employees,...

Are Shelters in Place? Mapping the Distribution of Transit Amenities via a Bus-Stop Census of San Francisco

Moran, Marcel E
2022

Transit stops serve as crucial components of journeys for riders, but their condition is often left out of equity considerations. Two important empirical questions are what stop amenities, such as places to sit, clear sign age, shelters for inclement weather, and unobstructed curbs are present, and how are they distributed across systems, which may reveal neighborhood or route-specific disparities. San Francisco, CA represents an ideal case for which to pursue this question, given it maintains a ‘transit first’ policy directive that mandates public space prioritize transit over private...

Heightening Walking Above its Pedestrian Status: Walking and Travel Behavior in California

Blumenberg, Evelyn
2016

People walk a lot—to walk pets, to exercise and recreate, and to access public transit and local shops. Walk trips begin and end almost every journey, even trips made by automobile. Data from the current California Household Travel Survey (CHTS) show that walking occurs more than trips by both transit and bicycle, making it the second most common travel mode in California. Yet outside of select case studies in specific metropolitan areas, we know very little about walking behavior in California. An improved understanding of the determinants of walking will aid efforts to reduce driving and...

Rail + Property Development: A Model of Sustainable Transit Finance and Urbanism

Cervero, Robert
Murakami, Jin
2008

Hong Kong has aggressively pursued transit value capture to finance railway infrastructure through its “Rail + Property” development program, or R+P. More than half of all revenues received by the MTR Corporation, the owner-operator of Hong Kong’s largest railway network, come from property development. A wide variety of R+P projects presently exist in Hong Kong. Most focus on housing development though all have some degree of commercial development. Recent generation R+P projects have placed a stronger premium on urban design and quality of pedestrian environments. This has generally paid...

How Network Structure Can Boost and Shape the Demand for Bus Transit

Badia, Hugo
Argote-Cabanero, Juan
2017

Conventional wisdom states that transit riders are averse to transfers and that consequently bus networks should be designed to limit their number. Probably as a result of this belief, many real bus systems try to connect as many origins and destinations as possible without transfers, so they are usually composed of long, circuitous routes with redundant overlapping sections – and the resulting bus map is hard to understand. If coverage is extensive, many routes are needed. Economics then prevents an agency from populating all routes with sufficient buses to provide attractively frequent...
