Knowledge-workers and the sustainable city : the travel consequences of car-related job-perks

Attracting firms in knowledge and technology intensive (KTI) sectors is highly desired at both the national and the regional level as a powerful engine of economic growth. Due to fierce competition in KTI sectors and national taxation policies, KTI firms often attract high-quality employees by offering car-related job perks as additional incentives to wage. In Canada, car allowance is offered by 46% of the employers to attract highly-skilled workers. In Israel, 61% of knowledge-workers in the KTI sectors receive a company-car with respect to 16% of workers in other sectors. In the U.K., car-related job perks are offered by 18% of the employers. This study focuses on the impact of car-related job-perks on the travel behavior of knowledge-workers. The importance of this issue derives from the impact of the travel behavior of knowledge-workers on congested transportation networks in metropolitan areas, as knowledge-based economy tends to concentrate mainly in metropolitan regions. This study applies discrete choice models in order to analyze the impact of company-cars and car allowances (reimbursement of fuel and parking expenses) on commute and leisure travel of knowledge-workers. The analyzed data consist of 750 observations, retrieved from a revealed-preferences survey among KTI workers who work and reside in the Tel-Aviv metropolitan area in Israel. Results show that car-related job perks are associated with (i) high annual mileage, (ii) high propensity of using the car as main commute mode, (ii) long commute distances and travel times, (iii) high trip chaining frequency in commuting trips, and (iii) high frequency of long-distance weekend leisure trips. Result also show that KTI workers generally prefer the car or non-motorized transport modes over the bus system. These results suggest that the development of sustainable knowledge-based cities should consider (i) the replacement of car-related job perks by other incentives, (ii) the provision of pedestrian and cyclist friendly infrastructures, and (iii) public transport improvements.
