Plan Alternatives <br /> <br /> Chapter Summary <br /> <br /> · The Transportation Service Objective of Level of Service E for the freeways cannot <br /> be met at the gateways based on demand, without spending over $2 billion on <br /> transportation improvments--far in excess of the funding that could reasonably be <br /> av · - ~s .............................. t- <br /> <br /> · Even if there were no further development in the Tri-Valley, the freeway system <br /> would still become increasingly congested by long-distance commuters that neither <br /> live nor work in the Tri-Valley. (This assumes that neighboring communities will <br /> continue to grow as planned.) <br /> <br /> · The plan should restrict increases in gateway capacity for single-occupant vehicles, <br /> insure that the internal transportation system operates at acceptable levels of <br /> service through selective network improvements and freeway ramp metering, and <br /> achieve a jobs-housing balance. Ridesharing and transit usage should be particu- <br /> larly emphasized at the gateways. <br /> <br /> This chapter describes the alternatives tested to develop the Tri-Valley Transportation <br /> Plan. Potential actions and strategies to address the projected transportation deficien- <br /> cies were developed by the consultant, the TAC and the TVTC. These actions and <br /> strategies can generally be divided into three groups: increase transportation supply <br /> through highway investment, increase transportation system efficiency through more <br /> reliance on transit, and decrease transportation demand through land use adjust- <br /> ments. Note that the evaluation of transportation alternatives was conducted with the <br /> baseline forecasts and did not include the gateway constraint concept. <br /> <br />Barton-Aschman Associates, Inc. 103 <br /> <br /> <br />
