MEASURING LEVELS OF SERVICE OF A CITY STREET BY USING ENERGY-MOMENTUM TECHNIQUES

A traditional speed and delay study can yield extremely useful information for the evaluation of traffic operations and flow. Unfortunately the results are deterministic, and traffic flow is highly stochastic. Energy-momentum theory recognizes this; however, its applications have primarily been for freeways and expressways. This study applies energy-momentum theory to a city street without access control. Little correlation was found between derived acceleration noise and average speed relationships. Traffic flow inhibited by delay is stochastic, yet, because the number of delays increases, the aperiodic nature of delay frequency does not lend itself to the energy-momentum model. Each delay type must be handled separately.
