| 摘要： | The City of Lincoln, Nebraska, with a current population of 215,000 is growing at about 1.3% each year. Increasing traffic volumes are a growing concern to public officials and citizens alike. The streets serving the older sections of the city are of particular concern because of the divisions of opinion regarding the need for widening these streets. In 1995, the Mayor of Lincoln appointed a "citizen task force" to study the need for traffic improvements on five key segments of these streets and recommend a program for improvement. The task force sought a congestion measure which could be applied (as a matter of public policy) to determine when, and to what extent, improvements would be made to these streets, i.e., the term "trigger mechanism." The primary measure of congestion agreed upon by the task force was "average travel speed" along these streets. This measure would be used to determine the level of congestion and to establish threshold values which would "trigger" successive levels of study and improvement. |
