On Transportation Equity Implications of Connected and Autonomous Vehicles (CAV) A Review of Methodologies

This review brings together the bodies of literature on transportation equity analysis, travel behavior forecasting, and impacts of CAVs, with the ultimate objective of highlighting important research needs for measuring the transportation equity implications of CAVs. In comparison to previous reviews of social impacts of CAV our focus is specifically on the state of current methods for accessing the transportation equity implications of CAVs. We seek to provide a summary of the methods used to assess potential impacts of CAV’s and how these impacts are likely to apply for transport disadvantaged communities. Our review highlight some critical gaps in available methods for measuring potential equity impacts of CAVs. We find that Our while a range of methods exists that may be applied to begin building our understanding of CAV equity implications, clear guidance how to appropriately apply these is warranted.http://deepblue.lib.umich.edu/bitstream/2027.42/162824/5/On Measuring the Transportation Equity Implications of Connected and Autonomous Vehicles (CAV) A Review of Methodologies.pd

A review and critique of UK housing stock energy models, modelling approaches and data sources

The UK housing stock is responsible for some 27% of national energy demand and associated carbon dioxide emissions. 80% of this energy demand is due to heating (60%) and domestic hot water (20%), the former reflecting the poor average thermal integrity of the envelope of the homes comprising this stock. To support the formulation of policies and strategies to decarbonise the UK housing stock, a large number of increasingly sophisticated Housing Stock Energy Models (HSEMs) have been developed throughout the past 25 years. After describing the sources of data and the spatio-temporal granularity with which these data are available to represent this stock, as well as the physical and social phenomena that are modelled and the range of strategies employed to do so, this paper evaluates the 29 HSEMs that have been developed and deployed in the UK. In this we consider the models' predictive accuracy, predictive sensitivity to design parameters, versatility, computational efficiency, the reproducibility of predictions and software usability as well as the models' transparency (how open they are) and modularity. We also discuss their comprehensiveness. From this evaluation, we conclude that current HSEMs are lacking in transparency and modularity, they are limited in their scope and employ simplistic models that limit their utility; in particular, relating to the modelling of heat flow and in the modelling of household behaviours relating to investment decisions and energy using practices. There is a need for an open-source and modular dynamic housing stock energy modelling platform that addresses current limitations, can be readily updated as new (e.g. housing survey) calibration data is released and be readily extended by the modelling community at large: improving upon the utilisation of scarce developmental resources. This would represent a considerable step forward in the formulation of housing stock decarbonisation policy that is informed by sound evidence

Ridesourcing and Travel Demand: Potential Effects of Transportation Network Companies in Bogotá

This paper proposes a modal-shift analysis methodology based on a mix of small-scale primary data and big data sources to estimate the total amount of trips that are reallocated to transportation network companies (TNCs) services in Bogotá, Colombia. The analysis is focused on the following four modes: public transportation, private vehicles, conventional taxis, and TNC services. Based on a stated preferences survey and secondary databases of travel times and costs, the paper proposes a methodology to estimate the reallocation of travel demand once TNCs start operating. Results suggests that approximately one third of public transportation trips are potentially transferred to TNCs. Moreover, potential taxi and private vehicle–transferred trips account for almost 30% of the new TNC demand. Additionally, approximately half of the trips that are reallocated from public transport demand can be considered as complementary, while the remaining share can be considered as potential replacing trips of public transportation. The paper also estimates the potential increase in Vehicle-km travelled in each of the modes before and after substitution as a proxy to the effects of demand reallocation on sustainability, finding increases between 1.3 and 14.5 times the number of Vehicle-km depending on the mode. The paper highlights the role of open data and critical perspectives on available information to analyze potential scenarios of the introduction of disruptive technologies and their spatial, social, and economic implications

On the Right Track: A Framework for Evaluating Commercial Corridor Revitalization in New Orleans

The purpose of this thesis is to provide leaders with a clear explanation of commercial corridor revitalization, standard for evaluation, and justification for the support of existing and future commercial corridor revitalization districts in New Orleans, LA. This thesis begins with a definition of commercial corridor revitalization and discussion of how it has been applied in New Orleans, LA. A standard framework for commercial corridor revitalization development and assessment is also established with several steps for implementation included. To test the feasibility, significance and relevance of the proposed framework, all of the steps mentioned were implemented in the New Orleans East Town Center Case Study. Key findings of this research may contribute to the providing a tool that evaluates criteria for evaluating city-wide policies to support the sustainability and vitality of existing and future commercial corridor revitalization districts in New Orleans, LA
