Road construction noise prediction and measurement - a case study
Noise predictions and measurements have been made during the earthworks phase of road construction. Measurements over periods of six hours or more showed that levels at the site boundary ranged from 70 to 83 dB(A) and at 30 m from the boundary ranged from 62 to 75 dB(A). The main eatrhworks operations occupied between 10 and 20 days in any one location. It is shown that the method of prediction…
The optimisation of public transport in small towns
A study was carried out with the aim of determining the optimum form of public transport for the town of Carterton, Oxfordshire. A demand model was developed and calibrated and was shown to be in close ageement with observations for three different levels of public transport in the town. This model was used to predict the variations of demand with fare and level of service for three different t…
Results of the first phase of the Solihul dial-a-bus experiment
A detailed analysis is presented of the operation, ridership and financial performance of the first phase of the Solihull dial-bus service. The service operated from December 1975 to July 1977 and employed a maximum of 4 buses between 0620 and 2345 from Monday to Saturday. An average of just over 1000 passengers were carried each day, over one-third of whom were children. Although 30 percent of…
Costs of noise control during earthmoving
Trrl Lr 751 The report describes methods of noise control which can be applied to earthmoving operations at road construction sites. Estimates of the cost penalties for the various methods are discussed for the conventional plant used in earthworks, together with an assessment of belt conveyors as an alternative strategy. The provision of noise barriers and double glazing, changes in operati…
