Commercial Vehicle Loading Zone Delivery Envelope Measurements and Simulator Data

The CVLZ measurement database (in the report) contains measurements, tailored to different types of truck configurations, loading equipment and accessories, of the operating envelope around a commercial vehicle. Three different data types were obtained from Oregon State Driving and Bicycling Simulator Laboratory for purpose of this report and they are as follow: 1) Pre-post survey data (all included in one excel file) consists of series of questions that were answered in an online Qualtrics survey by 48 participants to a) identify their demographic variables, and b) map their self-reported responses to their behavior while riding through the experiment so that results can be validated. 2) Speed data was collected based on the cyclist’s speed while riding through the scenarios. For each scenario, the average speed (m/sec) of 48 cyclists from 25 meter before the location of the commercial vehicle to 15 meter after was recorded. 3) Lateral position data was collected based on cyclist’s divergence from the center of the bike lane. The average lateral position (m) of 48 cyclists from 25 meter before the location of the commercial vehicle to 15 meter after for each independent variable level was recorded. Note that center of the bike lane was defined as 0 m making the left edge -0.92 m (travel lane side). 50 participants were recruited, two of them had a simulator sickness so they were excluded from the data and the analysis. Therefore, the data has no quality or consistency issues and it is ready to be used. The average values were calculated to easily apply the optimal statistical analysis for such data (speed and lateral position). As the experiment consists of 3x3x2 factorial design, each participant had to ride 18 scenarios; therefore, 864 observations were obtained and recorded in the excel file.
