The report documents the results of field studies to assess driver response to freeway lane control signals (LCS) installed on a section of I-35W in Ft. Worth, TX. TTI researchers evaluated several alternative LCS configurations upstream of single- and double-lane closures. Researchers conducted all studies during daylight, off-peak traffic conditions. Study results indicate that the LCS had no significant effect on travel speeds approaching and passing by the lane closures. The LCS were found to elicit a small but consistent shift in lane distributions from the closed lanes to open lanes upstream of the actual lane closure. Because of study limitations, direct comparisons between the yellow and red X upon lane distributions could not be made.
