Understanding the Shortest Route Selection Behavior for Private Cars Using Trajectory Data and Navigation Information

Table 1

The shortest path selection proportion in existing studies.

Area	Data profile	Shortest distance		Shortest time (%)
Boston [3]	Traffic survey of 188 respondents (1997)#	Simulation	28%	45
Turin [4]	276 observations of Turin Polytechnic faculty	Simulation	30.93%	18.22
Lexington [2]	216 drivers over a week, more than 3000 trips	Null
Minneapolis-St. Paul [6]	143 subjects, 25157 trips (2008)	Null^@		34
Minneapolis-St. Paul [5]	50 persons, 124 commute trips (2011)	12.26%		24.19
Enschede [8]	317 respondents, 624 trips	54%		41
A European country [9]	526 users over 18 months	47%
The Philippines and Japan [7]	17 driver participants	Null		21.6

Note: ^#survey time of the data; most drivers choose a path that deviates from the shortest path; ^@the ratio that excludes shortest time paths is 0.
