The decongestion strategy of Maseru Bridge was informed by a research exercise investigating different border post decongestion measures and border precinct typologies. Generic design parameters for border post decongestion strategies were compiled. Each measure and typology was evaluated against the generic design parameters. A short list of three decongestion strategies was determined. The capacity requirements of each was determined based on data surveys at the existing border crossing which determined the travel needs for light vehicles, public transport vehicles, freight vehicles and pedestrians. Design years and directional and seasonal peaks were taken into consideration when the patronage forecast was estimated. A spreadsheet based queueing model was developed to determine the number of entry lanes, number of parking bays and queueing capacity required for each decongestion strategy. The model took consideration of a large variety of design related constraints or parameters. The generic design parameters in conjunction with the capacity requirements as provided by the queueing model were taken into account in the conceptual design of the different border precincts.
