T2030 - Transportation and Land Use

There is a growing acceptance in the transportation planning community that the effects of transportation and land use are highly interrelated.

Thus, it is vitally important that transportation and land use planning be closely coordinated.

T2030 - Transportation and Land Use

Two factors in particular are stretching the transportation system to its limits:

1. the growth of suburban job centers and

2. suburban housing development. The dispersal of the region’s population by

increasing suburbanization is a major factor in increased trip-making and traffic congestion.

Public Transportation and Land Use Policy

While incentives and improved service can increase mobility by public transit,

These improvements by themselves are NOT enough to reduce auto use.

People with autos available will choose to drive, unless restrained by an obstacle such as high nonresidential density.

The positive features of good transit service have relatively little effect on them.

Land Use Policies that Reduce Auto Usage

Number One Increase Density in

Urban Centers

10 - 50 million square feet/square mile of gross non-residential floor space will be needed to attract an appreciable proportion of trips by transit.

Land Use Policies that Reduce Auto Usage

Number Two Exceed Auto Capacity

in Urban Centers

Urban Centers must exceed their capacity for automobiles before riders will switch by choice to transit.

(roughly 23,000 vehicles/S.M.)

Number Three Increase Nearby

Residential Density

Increasing residential density within 2.5 miles of Urban Centers of 25 million square feet is far more important than increasing density 10 miles away.

Number Four Building Transit Oriented

Developments

Concentrating residential density within 2000 feet of a transit station will generate the most transit riders.

The same density spread out within one square mile will

Final Thoughts

Are we prepared to plan land use with sufficient density to support transit?

Can we do that under current locally controlled zoning regimes?

Are we prepared to deliberately build an alternative transportation system to the automobile?
