VCI, A Regional Volume/Capacity Index of Urban
Congestion NEW |
A
simple, analytic model estimates regional average congestion delay (veh-hr/veh-mile)
as a function of three explanatory variables available on DOT databases. Calibrated to the TTI results, it
replicates TTI delay estimates to a standard error of 0.04 minute/mile. Making the TTI results available in
analytic (rather than data table) form makes possible a number of illustrated
new closed-form results including,
benefit/cost of freeway additions, external congestion, economically
efficient tolls, and point of diminishing returns or least-total cost. |

A Win-Win
ROW Policy |
OCTA
has tacitly adopted a policy of no more residence takings for freeway ROW. In
the long term this can only result in traffic strangulation. In a recent
instance, the present value of the time savings foregone on account of this
policy was 800 times the real estate value of the homes not taken. A proposed
rational ROW takings policy that shares the vastly increased value of
property used for ROW between owners and drivers. 9/27/7 |

The Only Solution
to Congestion |
Congestion. How we got here. How we cannot solve it. How we can solve it. There is no rational alternative. A Register commentary by ye webmaster. 3/11/03 |

The
Best Investment a Nation Ever Made |
A tribute to the Dwight Eisenhower Interstate Highway system. Cost/benefit analysis concludes that the national highway system has repaid more than three times its estimated cost of $329 billion (in 1996 dollars). |

The Public
Cost of Transportation Alternatives |
Compilation of total (operations and capital) average government gross and net cost, performance, and cost- effectiveness for all US public transit and road systems based on latest (1999) US DOT data. Gross cost per unit transportation ($ per person-mile) varies over a range of from $0.03/ps-mi (roads) to $1.29/ps-mi (light rail). Net costs accounting for user fares or fees vary from $-0.00 to $1.15. 4/12/03 |

Highway Subsidies NEW REVISED |
Revision of an earlier, 1993 paper, updated with current (2004) data evaluating the government net cost of roads and highways. Improved and updated data sources show that in 2004, highway user fees exceeded total expenditures for roads and highways at all levels of government by $66 billion, a profit of 45% on expenditures. 8/12/07 |

Critique of
the STPP Congestion Burden Index |
The Surface Transportation Policy Project has defined a Congestion Burden Index (CBI) which purports to show that cities with more transit usage suffer a lesser burden of congestion. This critique, by David Mootchnik, shows that the result is a tautology, inherent in the definition of the CBI, and not a valid measure of transit benefit. 9/08/01 |

Roads/Transit
Equity |
OCTA's allocation of resources between roads and transit is vastly out of proportion to quantifiable, rational measures of cost effectiveness, need, benefit, balance and equity. 11/10/01 |

Traffic Congestion:
A Solvable Problem |
A paper by Peter Samuel arguing that we can --- and showing with many working examples how to --- build our way out of urban traffic congestion with separate truckways, tunneling, and congestion tolling. |
