What data should form the foundation for scientific transportation planning and urban mass transit design_____________?
Show answer Hide answer
Answer: B. origin and destination data
Explanation
Origin and destination data provide fundamental travel patterns needed for scientific transportation planning and transit design. Surveys reveal where trips begin and end, helping planners identify major commuting corridors and travel demands. This comprehensive spatial information enables the optimal routing of new highways and public mass transit systems. Origin and destination surveys capture trip generation, distribution, and modal split data across urban transportation networks. Data collection methods include roadside interviews, home interviews, license plate tracking, and mobile phone data analysis. Transportation models use this information to forecast future traffic growth and evaluate infrastructure investment needs.
Option A names spot speed data, which measures instantaneous vehicle velocities rather than overall trip patterns. Option C refers to traffic volume data, counting vehicle numbers without indicating where travelers start or finish trips. Option D mentions accident data, which is essential for safety improvements but insufficient for transit route planning.
