Implementation of Highway Capacity Manual-based volume-delay functions in regional traffic assignment process

摘要: Recent model development efforts for the travel demand forecasting process have focused on increasing consistency and reasonableness of results. A major target these has been traffic assignment and, more specifically, improving estimates congested speeds resulting from assignments. number studies enhancements centered volume-delay functions used process. Many workhorse function, BPR investigated modifications to function coefficients. In its recent update Albuquerque Area Travel Models, Middle Rio Grande Council Governments successfully implemented a regional based capacity estimation techniques documented in Highway Capacity Manual. The procedures developed area resulted that produced accurate volumes whil...
