Analysis of Parking Space Adequacy and Design in Shopping Malls in Port Harcourt

The growth of shopping mall development in Port Harcourt has generated significant urban mobility challenges, with inadequate parking provision and poor parking design contributing to street congestion, pedestrian safety hazards, and a degraded urban environment in commercial corridors. This study analyses parking space adequacy and design quality at four major shopping malls in Port Harcourt: Rumuola Mall, Garden City Mall, Trans-Amadi Shopping Centre, and Waterlines Mall. Physical surveys measured available parking capacity, parking space dimensions, circulation aisle widths, surface marking legibility, entrance and exit configuration, loading bay provision, accessible parking bays, and landscaping. Traffic counts during peak shopping periods were conducted to estimate actual demand against supply. Customer surveys administered to one hundred and sixty mall visitors collected journey mode data, parking satisfaction ratings, and travel time to access parking. Results show that three of four malls operate at over one hundred and twenty percent of parking capacity during Saturday peak periods, generating significant on-street overspill. Parking bay dimensions were sub-standard in forty-one percent of surveyed spaces. Accessible parking bays were absent or non-compliant in three malls. Pedestrian circulation within parking areas was unprotected in all four cases, creating safety conflicts with vehicle movements. The study argues that current Port Harcourt mall planning approvals inadequately address parking demand generation and recommends a revised parking demand assessment methodology calibrated to Nigerian retail travel behaviour patterns.
