Pedestrian safety at midblock crossings relies on accurate speed and gap judgment, as misjudgement can lead to unsafe decisions and increased conflict risk. This study examines the relationship between perceived speed and gap acceptance at six-lane divided roads in Bhubaneswar, India. Two field experiments conducted with 324 participants assessed speed estimation (estimated the approaching vehicle’s speed), and gap acceptance (decided whether to accept or reject the gap for safe crossing), yielding 1,858 speed estimations and 1,917 gap decisions. Results show pedestrians underestimate vehicle speeds by 1.66 kmph, leading to accepting shorter gaps (2.65 seconds). Older pedestrians, females, and frequent crossers accepted longer gaps and showed better speed perception. The generalized linear model revealed that crossing frequency and interactions among vehicle type, age, gender, and speed difference significantly influenced the gap acceptance rate. Based on results, marked crossings, speed calming measures, and awareness programmes can effectively reduce risky pedestrian crossing behaviour.
