A Data-Driven Functional Classification of Urban Roadways Based on Geometric Design, Traffic Characteristics, and Land Use Features

Table 2

Linear regression model, the effect of independent variables on the dependent variable separately.

Tests	Independent variable	Dependent variable	Standard regression coefficient (β)	Significant level (p-value < 0.05)
1	Angle of access	Spot speed	−0.49	Ok
2	Total ramp density	Spot speed	−0.25	Ok
3	Number of lanes from the access point to the roadway	Spot speed	−0.17	Ok
4	Number of lanes in the roadway	Spot speed	−0.014	Not ok
5	Volume	Spot speed	−0.15	Ok
6	On-street parking	Spot speed	−0.67	Ok
7	Deceleration and acceleration lanes	Spot speed	0.58	Ok
8	Land use	Spot speed	−0.51	Ok
