Patterson Z., Bierlaire M. (2010). Development of Prototype UrbanSim Models. Environment and Planning B 37 (2):344-366

UrbanSim is an integrated transportation land-use model that has been under development since the late 1990s. It has received a significant amount of attention in the integrated modeling community. It is well known for its disaggregated approach. A number of papers describing the application of UrbanSim have appeared in the formal and gray literatures. Some of these papers report on successful applications of UrbanSim with little description of the amount of effort required to develop an operational model. Those that do report on the effort and challenges of using UrbanSim suggest that substantial data and human resources are required. One recent report quantifies the human resource requirements as an interdisciplinary team of four for three years. This reputation makes many potential users think twice before developing an UrbanSim model. We believe the best way to evaluate UrbanSim for a new region is by having a sense of how it can be used, and how much effort is required to do so. Understanding UrbanSim, however, does not require having a fully operational model. This paper is aimed at researchers and institutions that would like to evaluate UrbanSim, but are concerned about the effort required to do so. Based on two applications (Brussels in Belgium and Lausanne in Switzerland), it describes a procedure to develop a prototype UrbanSim model and how to use it to evaluate UrbanSim for application to a new region. Its objective is to motivate, describe, comment and illustrate a procedure for an efficient evaluation of the use of UrbanSim. Its main contributions are threefold. First, it develops a procedure by which a prototype UrbanSim model can be developed for evaluation purposes in a new region. Second, it provides an analysis of the effort required to do so. Finally, in so doing it advances knowledge in the field of transportation and land-use modeling by helping modelers to evaluate the use of UrbanSim for a particular study region, in a rigorous and systematic way.

Patterson Z., Ewing G., Haider M. (2008). The Potential for Premium-intermodal Services to Reduce Freight CO2 Emissions in the Quebec City - Windsor Corridor. Transportation Research Part D: Transport and Environment 13 (1):1-9

The Quebec City-Windsor corridor (the Corridor) is the busiest and most important trade and transportation corridor in Canada. The transportation sector is the second largest greenhouse gas (GHG) emission category in the country. This paper develops estimates of the potential for CO2 emission reductions in the freight transportation sector by estimating demand for premium-intermodal services between the main Corridor destinations. CO2 reductions are estimated on the basis of a stated-preference carrier-choice survey of shippers in the Corridor. Survey data were used to develop mode share models for five different categories of shipments between eighteen city-pairs. A railyard-catchment approach was taken to arrive at estimates of contestable intercity truck traffic using a subset of the Ontario Ministry of Transportation’s Commercial Vehicle Survey. CO2 emissions were based on current truck traffic estimates, and emissions factors obtained from MOBILE6.2C. The results show that premium-intermodal service has the potential to capture a significant share of traffic between the main Corridor destinations with potential CO2 emissions reductions in the range of 0.058 to 0.484 Mt a year.

Patterson Z., Ewing G., Haider M. (2007). Shipper Mistrust of Rail Use: First Stated Preference Carrier Choice Survey for the Quebec City - Windsor Corridor. Transportation Research Record 2008 :67-74

The Quebec City-Windsor corridor is the busiest and most important trade and transportation corridor in Canada. The transportation sector is the second largest contributor to greenhouse gas (GHG) emissions in the country. Governments around the world, including Canada, are considering increased mode share by rail as a way to reduce transportation emissions. To understand whether freight mode shift is a realistic means to reduce transportation emissions, an analytical model is needed that can predict the effect of government policy on mode split. This paper presents the findings of the first such model developed for the Quebec City-Windsor Corridor. The model itself is a stated preference carrier choice model of shippers in this busy corridor. The model was developed using the results of a stated preference survey undertaken in the fall of 2005. The survey was designed explicitly to evaluate shipper preferences for the carriage of intercity consignments, and particularly their preferences for carriers that contract the services of rail companies to carry these shipments via rail. The results of the study show that shippers are very mistrustful of using rail to move their consignments and suggests that increasing rail’s share of freight faces tremendous challenges.

Patterson Z., Ewing G., Haider M. (2005). A Gender-based Analysis of Work Trip Mode Choice of Suburban Montreal Commuters Using Stated Preference Data. Transportation Research Record 1924 :85-93

Transportation literature suggests that men and women have different characteristics with respect to commuting patterns, as well as with respect to their propensity to switch between travel options. In North America, women are expected to have an increasing impact on travel demand. As such, differences in female responses to travel demand management strategies are likely to become increasingly important as governments try to curtail travel demand in the future. This paper uses a 1994 stated preference (SP) survey of suburban commuters in Montreal to: determine whether there is evidence for differences between men and women in the factors that affect work trip choices; quantify those differences; and suggest what these differences imply for travel demand management in the future in Montreal. The main conclusions of this paper are as follows. First, women and men should be modeled separately with respect to work trip mode choice. Second, there are three main differences that appear from the econometric models: women are less likely to choose public transit than men; women are more likely to choose to rideshare; and women are less time sensitive when it comes to commuting than men are.

Supervision: Zachary Patterson
La mod�lisation de transport est un aspect fondamental de la planification de transport. Plusieurs diff�rents logiciels existent pour mod�liser la performance des r�seaux de transports urbains. Les logiciels EMME, TransCAD et PTV Vision sont parmi les plus utilis�s au monde pour mod�liser le trafic. Au sein du laboratoire TRANSP-OR existent d�j� des mod�les EMME et TransCAD de Lausanne. Pour faire conna�tre aux �tudiants de l'EPFL les diff�rentes options disponibles pour la mod�lisation de transport, le d�veloppement d'un mod�le PTV Vision de Lausanne est pr�vu. Le but de ce projet est d'utiliser les donn�es existantes pour monter un mod�le PTV Vision de la ville de Lausanne.

Calibration of on Integrated Transportation Land-use Model - UrbanSim for Brussels, Zemzemi Fatima and Stoitzev Iordanka (Mathematics)

Supervision: Zachary Patterson
Transportation and infrastructure planning requires a good understanding of future transportation demand. Traditionally, transportation demand analysis has focused primarily on the transportation system independent of its relationship with land-use and urban form. Integrated Transportation and Land-use Models (ILUMs) explicitly model these interactions. The TRANSP-OR laboratory currently has an operational land-use model (UrbanSim) for the city of Brussels in Belgium. The purpose of this project is to is to fine-tune UrbanSim for Brussels by improving the location, developer and land-price models. The analysis will take advantage of GIS land-use data for Brussels. The project will include an application of the modeling system to a practical transportation and land-use planning problem. The project will be undertaken in cooperation with Stratec of Brussels.

A Survey of Active Integrated Land-use Models around the World, Vignon Olayitan (Civil Engineering)

Supervision: Zachary Patterson
Traditional travel demand modeling has tended to ignore the important interactions between urban form and transportation demand and the performance of the transportation system. Integrated transportation land-use models (ILUMs) explicitly model these interactions. These models are becoming increasingly popular. Better understanding these models requires a better knowledge of how they are applied in different contexts. The purpose of this project is to undertake research to provide a summary of active ILUM applications around the world.

2006-2007

An Integrated Land Use Model Application to Brussels using UrbanSim, Samartzis Lefteris (Mathematics)

Supervision: Zachary Patterson
The interrelationship between urban form, transportation infrastructure and transportation demand has long been recognized. More recently, analysts have been developing Integrated Transportation and Land-use Models (ILUMs) to better understand and quantify these interrelationships. As a result, several modeling options are now available to develop ILUMs. One such model has already been applied to the city of Brussels in Belgium. UrbanSim is an increasingly popular alternative for integrated land-use modeling. The current study is intended to test the feasibility of applying UrbanSim to a city for which a fair bit of transportation and land-use data already exist, within a medium-term project timeline. The project is being undertaken in collaboration with Stratec in Brussels.
