    Men, Women, Job Sprawl and Journey to Work in the Philadelphia Region
    (2007-01-01) Weinberger, Rachel
    The observation that increasing dispersion of employment opportunities leads to decreased travel times is reflective of a short-rem/phenomenon. Census-reported journey-to-work travel time is examined for the greater Philadelphia region, showing that more people are commuting by automobile, a mode usually associated with shorter journey times, but are reporting longer trip times. The finding is counterintuitive as it coincides with a period when new jobs were established in outlying areas and the region experienced a net loss in jobs. The study concludes that as job opportunities disperse into lower density areas, Philadelphia's existing high-capacity systems are underutilized, and transportation systems throughout the region that were designed for relatively low demand are becoming overwhelmed in time. The net effect is a breakdown of both the urban mass transit systems and the suburban and rural highway networks, the latter because of overuse and the former because of underuse.

    The High Cost of Free Highways
    (2007-01-01) Weinberger, Rachel
    It is widely but not universally held that more roads mean more traffic. In spite of this evidence we are continually seduced by the notion that we can zone for low density to preclude traffic from occurring, that we can move far away from traffic that we can avoid it, and/or that we can build our way out of traffic. This low density race to the edge results in the ill-defined but expensive condition of sprawl. In a counter vein, New Urbanists, Advocates of Transit Oriented Development (TOD), and smart growth advocates have embraced the notion that traffic has always been with us and is here to stay, but we can make the most of our activity spaces by concentrating development, arresting the creation of new roads, and investing wisely in high capacity transportation systems.
