In particular, due to limited user traffic, a standard online experimentation method for the platform is the orthogonal traffic-assignment design (Tang et al.2010,Xiong et al.2020): The treatment assignments of different individual A/B tests are independent.
Traffic Assignment: A Survey of Mathematical Models and Techniques
The traditional transportation planning process [1, 2] has the following four stages, having traffic assignment as one of the four stages:1. Trip Generation: Trip generation involves estimating the number of trips generated at each origin node and/or the number of trips attracted to each destination node.This estimation is performed based on surveys conducted and generally uses a model that ...
A conjugate gradient projection algorithm for the traffic assignment
Convergent algorithms for solving the traffic assignment (route choice) problem that it formulates have been studied since the 1960s. The Gradient Projection Algorithm The gradient projection (GP) algorithm operates directly on the path space. It does not find auxiliary solutions that are at corner points of the linear constraint space.

This paper presents constrained Newton methods for solving path-formulated static traffic assignment problems. Column generation, orthogonal projection [4] or line search [14] can be incorporated into the solution procedure. With column generation, the active paths joining each OD pair are generated only when needed.

Maximally flexible assignment of orthogonal variable spreading factor
In universal terrestrial radio access (UTRA) systems, orthogonal variable spreading factor (OVSF) codes are used to support different transmission rates for different users. In this paper, we first define the flexibility index to measure the capability of an assignable code set in supporting multirate traffic classes. Based on this index, two single-code assignment schemes, nonrearrangeable ...

Methods for Traffic Flow Assignment in Road Networks
The most common algorithm for traffic flow assignment is the Frank-Wolfe algorithm and its extensions. In fact, the Frank-Wolfe algorithm is a gradient descent method. Initially, M. Frank and P. Wolfe developed their algorithm to cope with problems of quadratic programming [ 1 ]. However, this algorithm is able to solve more general ...
The Evolving Urban Form: Moscow's Auto-Oriented Expansion
Moscow appears to be preparing to offer its citizens both an automobile-oriented lifestyle and a transit-oriented one. The reduced commercial traffic should also make central Moscow a more attractive environment for tourists, who spend too much time traveling between their hotels and historic sites, such as the Kremlin and St. Basil's.
