     existing geometric design guidance related to interchange ramp is not speed-dependent even though intuition indicates spacing and speed are related. understanding the relationship between interchange ramp spacing, speed, and freeway operations is important. the objectives of this paper were to investigate relationships between weaving length and speed. within the research tasks several methods were utilized to assist in developing guidance on ramp spacing lengths. the methods or resources used to generate potential lengths included: findings from field studies at seven study sites, findings from simulation conducted as part of this research. suggested ramp spacings were developed for the entrance ramp to exit ramp.
