Mode Split

Mode Split, also called mode share or modal split, is the percentage distribution of total person-trips across different transportation modes including single-occupancy vehicles, carpools, public transit, walking, cycling, and emerging options like ride-hailing and micromobilityMicromobilityMicromobility refers to lightweight, low-speed transportation vehicles such as e-scooters, e-bikes, and shared bicycl.... Mode split is a key performance metric for transportation systems, reflecting how well different options serve travel needs and indicating the overall sustainability of a region's transportation patterns. Mode split data comes from household travel surveys, census commute questions (American Community Survey), transit ridership counts, and increasingly from passive data sources like mobile phone apps and transit smart cards. GISGISGeographic Information Systems (GIS) enable users to analyze and visualize spatial data to uncover patterns, relation... mapping of mode share by geography reveals spatial patterns where certain modes dominate, often correlating with density, transit access, parking availability, and demographic characteristics. Applications include transportation plan evaluation that tracks progress toward mode shift targets, transit investment justification that demonstrates unmet demand, parking policy reform that adjusts requirements based on actual driving rates, and climate action planning that quantifies emissions reduction from mode shifts. Mode choice models used in travel demand forecasting predict how changes in travel time, cost, convenience, and reliability would shift trips between modes, enabling planners to evaluate proposed investments and policies before implementation.
