Mixed Functions
- Authors: Huidan Xiao, Tao Yang
- Abstract summary: The more mixed the functions of an area has, the more possible its vitality may be.
Our study shows that the higher the degree of the road network structure has, the more likely it will attract functions' aggregation.
It also reveals that diversified local degree will help gather urban functions.

- Abstract: In the field of urban planning, road network system planning is often the
first step and the main purpose of urban planning is to create a spatial
configuration of different functions such as residence, education, business,
etc. Generally speaking, the more mixed the functions of an area has, the more
possible its vitality may be. Therefore, in this article, we propose a new
framework to study the specific spatial influence patterns of the overall
structure and different sub-structures of road networks on the mixed functions.
Taking road segment as the basic unit, we characterize mixed functions
aggregation of road networks with the number of POIs categories within 100
meters around every road segment. At the same time, on the basis of centrality
measurement in graph theory, we use 4 indexes to reflect the characteristics of
the urban road network structure, including degree, closeness, betweenness, and
length. We conduct our methods and experiments using the road networks and POI
data within the 5th ring road of Beijing. The results demonstrate that urban
road networks inherently influence the aggregation of urban mixed functions in
various patterns and the patterns of road network sub-structures is also quite
different. Our study shows that the higher the degree of the road network
structure has, the more likely it will attract functions' aggregation. It also
reveals that diversified local degree will help gather urban functions. In
addition to those, the analysis as well validates the importance of small-grids
typology of urban road networks and the closeness to the center of cities.

Perspective [0.0]
We investigate the relationship between the spatial scale of the modelled network entities against the amount of useful information contained within it.
We employ an entropy measure from complexity science and information theory to quantify the amount of information residing in each presentation of the network.
We find the critical spatial scale to be 85 m, at which the network obtained corresponds very well to the planning boundaries used by the local urban planners.

We propose using a neural embedding model-graph neural network (GNN)- that leverages the heterogeneous features of urban areas.
Using large-scale high-resolution mobility data sets from millions of aggregated and anonymized mobile phone users in 16 metropolitan counties in the United States, we demonstrate that our embeddings encode complex relationships among features related to urban components.
We show that embeddings generated by a model trained on a different county can capture 50% to 60% of the emergent spatial structure in another county.

As an application, we consider transportation networks, where each layer is associated to a different transportation system.
We show an example of this result on the real 2-layer network of the city of Bordeaux with bus and tram, where in certain regimes the presence of the tram network significantly unburdens the traffic on the road network.
