Transportation Mode Selection Standards Comparison Chart
A Transportation Mode Selection Standards Comparison Chart is a structured analytical tool—typically presented as a tabular or matrix-based resource—that systematically compares transportation modes (e.g., walking, cycling, transit, private vehicle, micromobility) across standardized evaluation criteria such as cost, travel time, environmental impact, accessibility, safety, and infrastructure requirements. It supports evidence-based decision-making for urban planners, transportation engineers, policymakers, and sustainability practitioners by quantifying trade-offs and contextual performance. The chart synthesizes normative standards (e.g., AASHTO, ITE, ISO, GHG Protocol) and empirical benchmarks to enable objective mode ranking under specific project or policy scenarios.

📐 Key Formulas
Modal Shift Potential Index (MSPI)
MSPI = Σ(w_i × (b_i − c_i) / b_i)
Quantifies relative improvement potential of shifting from baseline mode (e.g., single-occupancy vehicle) to target mode (e.g., bus rapid transit) across i criteria; w_i = weight, b_i = baseline score, c_i = candidate mode score
Total Cost of Ownership per Passenger-Kilometer (TCO/pkm)
TCO/pkm = (C_capital + C_operational + C_external) / (P × D)
Calculates full-cost economic burden per passenger-kilometer, where C_capital = amortized infrastructure/vehicle cost, C_operational = energy/maintenance/labor, C_external = societal costs (e.g., air pollution, noise, congestion), P = annual passengers, D = avg trip distance (km)
Carbon Intensity Ratio (CIR)
CIR = (gCO₂e/pkm_mode_A) / (gCO₂e/pkm_mode_B)
Compares greenhouse gas emissions intensity between two transport modes to assess climate mitigation leverage
