By quantifying properties like intersection density, block length, and network connectivity indices, analysts can evaluate how well a street grid supports efficient travel for vehicles, cyclists, and pedestrians. Core methods include centrality analysis, which identifies the most important streets for through-movement, and connectivity indices that compare actual connections to the maximum possible.

Transportation engineers evaluate how network structure affects traffic distribution and congestion patterns. Public health researchers correlate network walkability with physical activity levels.
