exclusive turning lanes near railroad tracks and identified hesitation
behaviors based on the following criteria (as shown in Figure 3):
ƒ	 Speeds of approaching vehicles are lower than the 15th
percentile of the collected sample within a data collection
period at a highway-rail crossing; these vehicles exhibit
abnormal speed.
ƒ	 Headways of vehicles with abnormal speeds are equal or
greater than 10 seconds; a long headway was used to exclude
the influence of leading cars on speed.

ƒ	 Other factors influencing low speed, such as a red signal,
incidents, or lane closure, were excluded from the
observations.

Study Sites and Data Collection
Pilot studies were conducted at six sites in Florida, as shown in
Table 1. These sites, including a railway grade crossing adjacent to
a signalized intersection and an exclusive turning lane connecting
an interstate on-ramp or a principal arterial road, have historical
