Abstract:

This report summarizes the research performed and documented in interim project reports to address visibility, spacing, and operational issues pertaining to lane control signals (LCSs) used for freeway traffic management in Texas. Chapters in this final report review the results of legibility studies of new and used LCSs; a TxDOT expert panel meeting to address LCS visibility, spacing, and mounting location issues; and an evaluation of yellow diagonal and downward arrows for freeway traffic management purposes. The final chapter summarizes the findings and recommendations resulting from this research effort.
