Urban studies (Planning and development)
Traders on Dublin’s two main shopping streets considerably over-estimate spending by shoppers travelling by car and Luas while significantly undervaluing the spend of bus passengers and pedestrians. A study interviewed 1,009 shoppers on Grafton and Henry streets seeking to identify differences (if any) between perceived and actual spending levels by travel mode. Bus carried 35% of shoppers to Grafton St and 49% to Henry St; this compares with traders’ perceptions of 31% and 40% respectively. Measured in value terms, bus proved the most lucrative mode to both streets, delivering 38% of the total spend on both streets, when outliers are excluded. Pedestrian travel was similarly under-valued. Traders believed that 11% would walk to shop on Grafton St while on Henry St traders estimated that 6% of their customers came on foot. The actual figures are 20% and 19%, according to the survey. Car transport was overvalued by traders. On Grafton St traders perceived that car would account for 13% of customers whereas in reality car-borne shoppers made up 10%. Traders on Henry St believed car would carry 19% of shoppers but in fact only 9% came by car. The situation is similar for Luas: traders perceived 28% of Grafton St shoppers would arrive by tram compared to 13% in reality, and again on Henry St, traders thought Luas would carry 19% but it served just 10%. Bus priority and pedestrian enhancement may therefore warrant greater investment. The imbalance in cycling mode share between Grafton Street and Henry Street should also be investigated further.
