Internal reductions occur within a site‚ such as using on-site amenities‚ while external reductions involve mode shifts or nearby facilities. Both factors help minimize overall trip demand. Factors influencing trip reductions include land use mix‚ transportation options‚ and site design. Mixed land uses reduce trips by enabling walking or biking. High-occupancy vehicles and public transit availability lower vehicle trips. Site design features‚ such as proximity to transit‚ also impact reductions. Understanding these factors helps in accurately estimating trip reductions for transportation planning and policy implementation. Calculation methods involve applying trip rate equations and adjustment factors. Data from land use characteristics and regional settings are analyzed. Peak-hour multipliers and mode-specific adjustments refine estimates. The ITE Trip Generation Manual provides standardized formulas and procedures to ensure accuracy. These methods help transportation planners estimate person trips and vehicle trips effectively‚ accounting for various influencing factors and land use types. Land use classification categorizes development types‚ linking them to trip rates. The ITE manual provides standardized classifications and trip rates‚ enabling accurate predictions of travel demand based on land use characteristics. Land use classification in the ITE manual is based on criteria such as development intensity‚ location‚ and functional characteristics. These criteria help categorize land uses into standardized groups‚ ensuring consistent trip generation estimates. The classification reflects urban‚ suburban‚ and rural contexts‚ providing a framework for accurate trip rate application in transportation planning and analysis. Trip rates are determined by analyzing data from similar land uses‚ considering factors like peak periods and site characteristics. The ITE manual provides average rates‚ but adjustments may be needed for specific conditions. Accurate trip rate determination ensures reliable estimates‚ aiding in transportation infrastructure planning and policy development. Multimodal trip generation integrates data on pedestrian‚ transit‚ bicycle‚ and truck trips‚ providing a comprehensive approach to transportation planning and infrastructure design. Multimodal trip generation requires analyzing pedestrian‚ cyclist‚ transit‚ and truck trips separately‚ as each mode has unique factors influencing trip production. Pedestrian trips depend on land use density and accessibility‚ while cyclist trips are impacted by infrastructure. Transit trips are shaped by route availability and frequency‚ and truck trips are influenced by logistics and land use.
