  • Adjusting ITE's Trip Generation Handbook for Urban Context
    THE JOURNAL OF TRANSPORT AND LAND USE http://jtlu.org . 8 . 1 [2015] pp. 5– 29 Adjusting ITE’s Trip Generation Handbook for urban context Kelly J. Cliftona Kristina M. Curransb Portland State University Portland State University Christopher D. Muhsc Portland State University Abstract: This study examines the ways in which urban context affects vehicle trip generation rates across three land uses. An intercept travel survey was administered at 78 establishments (high-turnover restaurants, convenience markets, and drinking places) in the Portland, Oregon, region during 2011. This approach was developed to adjust the Institute of Transportation Engineers (ITE) Trip Generation Handbook vehicle trip rates based on built environment characteristics where the establishments were located. A number of policy-relevant built environment measures were used to estimate a set of nine models predicting an adjustment to ITE trip rates. Each model was estimated as a single measure: activity density, num- ber of transit corridors, number of high-frequency bus lines, employment density, lot coverage, length of bicycle facilities, presence of rail transit, retail and service employment index, and intersection density. All of these models perform similarly (Adj. R2 0.76-0.77) in estimating trip rate adjustments. Data from 34 additional sites were collected to verify the adjustments. For convenience markets and drinking places, the adjustment models were an improvement to the ITE’s handbook method, while adjustments for restaurants tended to perform similarly to those from ITE’s estimation. The approach here is useful in guiding plans and policies for a short-term improvement to the ITE’s Trip Generation Handbook.

  • White Paper Series Bicycle and Pedestrian Forecasting Tools: State
    White Paper Series Bicycle and Pedestrian Forecasting Tools: State of the Practice April 2015 Alisar Aoun, Julie Bjornstad, Brooke DuBose, Meghan Mitman, and Mollie Pelon, Fehr & Peers For: Federal Highway Administration DTFHGI-11-H-00024 www.pedbikeinfo.org This material is based upon work supported by the Federal Highway Administration under Cooperative Agreement No. DTFH610110H-00024. Any opinions, findings, and conclusions or recommendations expressed in this publication are those of the Author(s) and do not necessarily reflect the view of the Federal Highway Administration. Introduction Transportation forecasting models predict levels of activity, and help inform decisions on issues such as future facility use and the prioritization of projects. Travel and demand forecasting methods have long been used to estimate the number of vehicles traveling on a specific street or network and to estimate ridership for mass transit. Many jurisdictions and metropolitan planning organizations use forecasting methods to determine the potential impact of new development, changes to roadway capacity, or projected ridership for new transit. However, these methods have traditionally excluded pedestrian and bicycle activity. For communities seeking to support walking and bicycling activity, quantifying the use and potential demand of facilities that support active transportation is increasingly important. To meet this need, bicycle and pedestrian forecasting models are being developed and integrated into planning projects focusing on facilitating mobility, managing resources, and improving health and safety. These emerging forecasting approaches vary widely in the amount of data and level of effort required. The type, specificity, and reliability of data also vary between different forecasting approaches. For example, data used in forecasting models can range from readily available U.S.

  • Trip Generation Rates and Land Use - Transport Planning in Urban Environment
    Transactions on the Built Environment vol 52, © 2001 WIT Press, www.witpress.com, ISSN 1743-3509 Trip generation rates and land use - transport planning in urban environment M. ~itsiava-~atino~oulou',G. ~sohos~ & S. ~asbas~ '.*~ristotleUniversity of Thessaloniki, School of Technology Faculty of Civil Engineering, Greece 3 Aristotle University of Thessaloniki, School of Technology Faculty of Rural & Surveying Engineering, Greece Abstract In order to assess the land use policy implications, trip generation rates is essential knowledge for both planners and engineers working in the field of town planning and transportation. Within the framework of this paper trip generation rates are presented for the Thessaloniki Metropolitan Area (T.M.A). The structure of the land use system in T.M.A evidently produces many problems in the transportation system. The results of research activities of the Laboratory of Transportation Engineering of A.U.Th concerning the trip generation rates regarding different land uses (education, administration, banks, cultural, hotels industry, hospitals) in T.M.A are presented and discussed. These results are in the fornl of mathematical equations that have been derived with regression analysis and take into account data resulting from properly designed questionnaire surveys. 1 Introduction The land use changes in urban and interurban areas affect, in most of the cases, the demand for trips. At a second stage, the new trips affect the transportation system and lead to the redesign of the transport infrastructure in order to satisfy the new demand. The improvement of the transport infrastructure positively affects the economic development of an area and thus, new land uses are attracted, which in turn increase the demand for new trips.

ABSTRACT Assessment and mitigation of transportation impacts based on travel demand is required by state, federal, and local laws in California. Determining trip generation is typically the first step in preparing these transportation impact analyses, and current industry standard practice relies on trip rates published by the Institute of Transportation Engineers (ITE). However, ITE protocols emphasize vehicle trip rates without sensitivity to urban context or socioeconomic characteristics, which can exaggerate the impact of certain land uses like affordable housing developments, ultimately increasing mitigation fees.

  • Introduction to Multi-Modal Transportation Planning Principles and Practices 23 April 2021
    www.vtpi.org [email protected] 250-508-5150 Introduction to Multi-Modal Transportation Planning Principles and Practices 23 April 2021 By Todd Litman Victoria Transport Policy Institute Abstract This report summarizes basic principles for transportation planning. It describes conventional transport planning, which tends to focus on motor vehicle traffic conditions, and newer methods for more multi-modal planning and evaluation.

Multi-Modal Transportation Planning Victoria Transport Policy Institute Introduction To be efficient and fair a transportation system must serve diverse demands. For example, would be inefficient if inadequate sidewalks and paths force parents to chauffeur children to local destinations to which they would rather walk or bicycle, or if inadequate mobility options force urban commuters to drive although they would prefer to rideshare or use transit. Physically, economically and socially disadvantaged people in particular need diverse mobility options: walking and cycling for local travel, public transit for longer trips, and automobiles (ridesharing, chauffeuring and taxi travel) when necessary. As a result, to be efficient and fair transportation must be multimodal. Before about 1940, walking, bicycling and public transit were recognized as important travel modes, but for most of the last century transport planning was automobile-oriented. As a result, most communities now have well developed road systems that allow motorists to drive to most destinations with relative convenience and safety; at worst they may be delayed by peak period congestion, and pay tolls and parking fees at some destinations.

  • Analysis of Trip Generation Rates in Residential Commuting Based on Mobile Phone Signaling Data
    T J T L U http://jtlu.org V. 12 N. 1 [2019] pp. 201–220 Analysis of trip generation rates in residential commuting based on mobile phone signaling data Fei Shi Le Zhu Nanjing University Nanjing University [email protected] [email protected] Abstract: In this paper, mobile phone signaling data are first processed Article history: to extract information such as the trip volume and spatial distribution Received: July 17, 2018 from the starting point to the termination point. This information is Received in revised form: then used to identify the residential and employment locations of users. August 31, 2018 Next, multiple Thiessen polygons based on cell towers are aggregated Accepted: November 27, 2018 into Traffic Analysis Zones (TAZs) to minimize differences between the Available online: March 28, actual cell tower coverage and the theoretical coverage. Then, based on 2019 TAZ cluster analysis involving transport accessibility and commuting population density, multiple stepwise regression is applied to obtain the commuting trip production rates and attraction rates for overall resi- dential land and each subdivided housing type during the peak morning hours. The obtained commuting trip generation rates can be directly applied to local transport analysis models. This paper suggests that as information and data sharing continue, mobile phone signaling data will become increasingly important for use in future trip rate research. Keywords: Trip rate, signaling data, commuting trip, trip generation, trip production, trip attraction 1 Introduction 1.1 About trip generation Trip generation is the first step in the conventional four-step transport forecasting process (followed by trip distribution, mode choice, and route assignment) and is widely used for forecasting travel demands.
