TRB 2011 - Evaluating the Effectiveness of the Travel Assistance DeviceSean Barbeau
Independence for individuals with disabilities can be facilitated through the use of devices that have been created and adapted for these individuals. Research regarding the use of technology to afford independence to those with disabilities is growing as new electronic devices are created. One such device is the Travel Assistance Device (TAD), a software application for mobile phones which provides real-time navigation guidance to public transportation riders. TAD has undergone technology proof-of-concept testing, which determined that TAD could provide timely prompts to transit riders at the programmed locations. The purpose of this research study was to determine whether the prompts given by TAD would exhibit stimulus control over the participant’s behavior of pulling the cord to stop the bus at the appropriate time and exiting the bus at the appropriate stop. TAD was evaluated in an ABAB design with three adults with mental retardation. Results show favorable outcomes for the 3 participants who were able to pull the bus cord at the appropriate stops and exit the bus only when TAD delivered prompts.
Presented at the National Academy of Sciences’ Transportation Research Board 90th Annual Meeting.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.
