Pedestrian safety in mixed traffic environments is a major concern, particularly in developing countries with diverse vehicle types and limited infrastructure. This study examines pedestrians' ability to estimate vehicle speeds and stopping distances at midblock crossings in Bhubaneswar, India. Two field experiments, each with 100 participants classified by age, gender, road-crossing frequency, and estimation point (kerb or median), recorded 1,174 speed and 1,038 stopping distance estimates. Results show that 61.58% of speed estimates were underestimated (mean error: -2.86 kmph), while 67.43% of stopping distances were overestimated (mean error: +15.21 m). Younger pedestrians and females underestimated speeds at higher speeds, while frequent road users showed improved accuracy in estimation. Nonlinear regression identified speed, gender, vehicle type, and estimation point as significant predictors. Males overestimated stopping distances at low speeds, while females underestimated at higher speeds. Findings highlight the need for public awareness programs and infrastructure improvements for safer crossings.
