ABSTRACT
This chapter will outline three subjective rating mental workload (MWL) assessment techniques. Each of these is valuable for the users of urban environments or indeed to explore practitioner land-use planning processes and to provide ratings of their perceived MWL during task performance. Subjective rating assessment techniques are also attractive due to their ease and speed of application, and also the low cost involved. They are also unobtrusive to primary task performance and can be used in the field in real-world urban settings. MWL assessment may assist in land-use planning and urban design (LUP & UD) to explore the inefficient use of or indeed abuse of valuable urban resources.
