CLASSIFICATION OF STREETS
For the effective planning of manual sweeping it is necessary to classify streets, or sections of streets, according to the required frequency of sweeping.
The following Table 11.1, shows a typical method of classification with the frequency of sweepings.
Each city should determine its own frequency requirements and develop an appropriate classification system. Time studies should then be carried out for each class of street and the results of these will indicate the length of street that a man can sweep at the required frequency. For example, time studies may show that for Class A streets one man can be allocated between 250 and 300 metres, while for Class F the length may be as great as 1.0 km. In measuring work content, sub-classification may be necessary to take account of variation in wastes generation within a given class.
Table 11.1 : A Typical Classification of Streets and the Frequency of Sweeping
Class Character of Street Frequency of Sweeping
A - City centre shopping - Daily
B - Market areas - Daily
C - City centre and minor streets - Daily
D - Sub-urban shopping streets - Daily
E - Residential streets (high & low income) - Daily
F - Roads and streets having no households/establishments on either sides - Once a week
G - Sub-urban main streets - Twice a week
H - Open space Occasionally, - when required. (minimum once in a fortnight)
On the basis of this information a city can be divided into sweepers’ beats which contain fairly uniform workloads, despite great differences in the lengths to be covered.
