Unbalanced Multiple Left Turn Lane Usage Modelling: From Individual Choice to Aggregate Volume

Table 3

Dynamic influential factors of individual LTL choices.

No.	Category	Name	Unit/Measurement
DF1	Turning curve	Skewedness	0=no, 1=yes.
DF2	Intersection approach	Queue length in inside LTL	Vehicle number; measured at the DLTLs/TLTLs.
DF3		Queue length in median LTL	Vehicle number; measured at the TLTLs.
DF4		Queue length in outside LTL	Vehicle number; measured at the DLTLs/TLTLs.
DF5		Queue length difference in inside and median LTLs	Vehicle number; queue length in median lane minus that in inside lane at the TLTLs.
DF6		Queue length difference in median and outside LTLs	Vehicle number; queue length in median lane minus that in outside lane at the TLTLs.
DF7		Queue length difference in inside and outside LTLs	Vehicle number; queue length in outside lane minus that in inside lane at the DLTLs.
DF8		Lane type of inside LTL	0=unshadowed, 1=shadowed.
DF9		Lane type of median LTL	0=unshadowed, 1=shadowed.
DF10		Lane type of outside LTL	0=unshadowed, 1=shadowed.
DF11		Available of shadowed LTL	0=no, 1=yes.
DF12	Vehicle type	Vehicle type at queue back in inside LTL	0=passenger car, 1=heavy vehicle; measured at the DLTLs/TLTLs;
DF13		Vehicle type at queue back in median LTL	0=passenger car, 1=heavy vehicle; measured at the TLTLs;
DF14		Vehicle type at queue back in outside LTL	0=passenger car, 1=heavy vehicle; measured at the DLTLs/TLTLs;
DF15		Number of heavy vehicles in inside LTL	Vehicle number; measured at the DLTLs/TLTLs.
DF16		Number of heavy vehicles in median LTL	Vehicle number; measured at the TLTLs.
DF17		Number of heavy vehicles in outside LTL	Vehicle number; measured at the DLTLs/TLTLs.
DF18		Number difference of heavy vehicles in inside and outside LTLs	Vehicle number; number of heavy vehicle in outside lane minus that in inside lane at the DLTLs.
DF19		Number difference of heavy vehicles in median and inside LTLs	Vehicle number; number of heavy vehicle in median lane minus that in inside lane at the TLTLs.
DF20		Number difference of heavy vehicles in median and outside LTLs	Vehicle number; number of heavy vehicle in median lane minus that in outside lane at the TLTLs.
DF21		Subject vehicle type	0=Passenger car; 1=Heavy vehicle.
