A little more than half of the driving in Hawaii happens on local roads: 70% of all vehicle-miles. A typical local road sees 9,654 vehicles per day.
Local roads make up 91% of the monitored road miles (1,972 miles in 31,296 segments) but carry less than their share of travel: 15,482,438 vehicle-miles traveled per day (≈5.7 billion per year). Trucks make up 5.4% of non-highway traffic, about 1 in 19 vehicles.
Older drivers than 88% of states nationwide
Local roads and highways carry about the same truck share here (5.4% against 5.4%), so freight is not confined to the highways.
At 54% higher than the national level, the non-highway congestion ratio of 28.2% signals more friction on local roads.
86% of states nationwide see lower average driver income among trip origins than Hawaii. The driver population here skews older than 88% of states nationwide.
