A number of strategies are proposed for the approach, including strategies for design variables reduction, variable dependency graph development, constraint propagation, and dynamic verification of a design over an assigned set of attributes (variables).
In discrete event simulation, entities can possess attributes (variables attached to those entities), allowing the depiction of different health states including age and prevalence.
Table 1 Summary of LiDAR attributes Variable Value Wavelength (nm) 1064 Scan angle (deg).
Model 1 is the estimated result of model with attribute variables only, while Model 2 includes attribute variables and interaction variables that are generated by interacting non-attribute variables (e.g., socioeconomic characteristics, knowledge and attitudes) with the alternative specific constant (ASC).
A questionnaire was well designed aiming at collecting pedestrians' socio-economic characteristics, trip related features, and attribute variables in different crossing facilities.
Other attribute variables such as gender and cause of expressway delay do not obtain coefficient of statistical significance in the cross-sectional binary logit model.
Table 1 Names, definitions, and hypothesized signs of variables used in the models Variable name Definition Hypothesized sign Dependent variable Chosen 1 if the alternative is chosen, 0 otherwise Explanatory product attribute variables Price ($, cents/km) 3.9, 4.1, 4.3, 4.6, and 4.8 (E0) or - 4.2, 4.4, 4.7,4.9, and 5.2 (E10) Import 10, 33, 50, and 60 imported - Inconvenience (min).
Further, all attribute variables were coded as dummy variables except for salary, which was specified as continuous in all models.
Further, all attribute variables were coded as dummy variables except for salary, which was specified as continuous in both models.
To understand how respondents' demographic and professional characteristics influenced their payment preferences, we also estimated models that included interaction terms for several variables with payment attribute variables.
In both models, all attribute variables were specified as having a random component except for salary, which was specified as fixed.
