The paper also analyzes the effect of intersection characteristics, such as geometric design, control system and location, on number of violations.
The optimal design of traffic light settings assumes in general that all the input parameters are known and constant for each design reference period, neglecting the effects of the uncertainty of the incoming flows or of other intersection characteristics, such as the saturation flows or the lost time.
The probabilistic approach takes into account the fact that the gap acceptance behavior depends not only on intersection characteristics, vehicular characteristics, opposing flow, type of control, but also on qualitative factors like drivers' psychological and socioeconomic status, factors related to weather, pavement and light conditions, and factors related to the vehicle occupancy.
For example, the working point (situated at the point of intersection of characteristics) corresponds to stable flow for coefficient resistance 20 in Fig. 2.
Yet, the viscoelasticity and nonlinear deformations inherent in an engineered, elastomeric material system having critically constrained internal constituents challenge the understanding of the macroscopic dynamic properties borne out of such intersection of complex characteristics.
The decision rules are either extracted from the existing parametric models of the indecision zone problem, or designed as novel ones based on physical models utilizing the integrated information containing the key inputs from vehicle motion, vehicle-driver characteristics, intersection geometry and topology, signal phase and timings, and the definitions of red-light running (RLR).
"Microscale" factors include details about streets, sidewalks, intersections, and design characteristics (e.g., road crossing features, presence of trees, bicycle lanes, curbs), as well as characteristics of the social environment (e.g., stray dogs, graffiti, trash) [ 8].
On an aggregate urban level, the pursuit of increased comfort during journeys [68] can lead to the selection of routes with less intersections or other characteristics, ultimately resulting in increased congestion and energy use.
The number of segments and intersections, and their characteristics, varied across neighborhoods (Table 3).
However, when groups of people are seen as collectively vulnerable, there is a risk that individual experience and intersections among diverse characteristics will be concealed.
