Evaluating Impacts and Problems
Updated June 2008 |
| Transportation Cost and Benefit Analysis: Techniques, Estimates and Implications |
This is a comprehensive study of transportation benefit and costing research,
and a guidebook for applying this information in policy and planning analysis.
It describes categories of transportation costs and benefits, and provides monetized
estimates of twenty costs for eleven travel modes under three travel conditions.
Examples illustrate how this information can be applied for transportation policy
and planning decisions. |
| Transportation Cost Analysis Summary |
This paper summarizes the comprehensive study, Transportation Cost and Benefit
Analysis; Techniques, Estimates and Implications. It discusses the importance
of transportation costing research, defines major cost categories, describes how
costs are estimated, summarizes major findings, and explores implications of this
research. |
| Smart Congestion Reductions: Reevaluating The Role Of Highway Expansion For Improving Urban Transportation |
This report investigates claims that highway capacity expansion is a cost effective and desirable solution to urban traffic congestion problems. It identifies errors in proponents' analysis that overestimate the congestion reduction impacts and economic benefits of roadway capacity expansion, overlook negative impacts of induced travel, and ignore more cost effective alternatives. |
| Smart Congestion Reductions II: Reevaluating The Role Of Public Transit For Improving Urban Transportation |
This report investigates the role that public transit can play in reducing traffic congestion and achieving other transportation improvement objectives. It evaluates criticism that urban transit investments are ineffective at reducing traffic congestion and wasteful. |
| The Future Isn’t What It Used To Be
Changing Trends And Their Implications For Transport Planning |
This paper examines demographic, economic and market trends that affect travel
demand, and their implications for transport planning. Motorized mobility
grew tremendously during the Twentieth Century, but the factors that caused
this growth are unlikely to continue. Per capita vehicle ownership and mileage
have started to decline in the U.S., while demand for alternatives such
as walking, cycling, public transit and telework is increasing. This indicates
that future transport demand will be increasingly diverse. |
| Safe Travels: Evaluating Mobility Management Traffic Safety Impacts |
This paper investigates the relationships between vehicle mileage and crashes, and the traffic safety impacts of mobility management, which consists of various strategies that increase transportation system efficiency by changing travel patterns. This analysis indicates that mobility management can be a cost effective traffic safety strategy, and increased safety is one of the largest potential benefits of mobility management.

more physical activity. Originally published in the American Journal of Health
Promotion. |
| Active Transportation Policy Issues: Backgrounder |
Active transportation consists of human-powered forms of travel such as walking,
cycling, skating, skiing, and manual wheelchairs. Active transportation provides
economic, social, environmental and health benefits. This paper provides background
information on active transportation to facilitate discussion at the Canadian
Active Transportation Roundtable held in 2003. |

reduction strategies. It finds mobility management strategies provide significant
additional benefits compared with “clean vehicle” strategies. |

Transportation improvements can encourage more and longer trips, changes in travel
patterns, and land use changes. This is called "generated traffic" or
"induced travel." This report defines various types of generated traffic
and discusses their impacts. |

“Positional” (also called “prestige”) goods confer status on their consumers. Positional value increases status to consumers of prestige goods but reduces status to others. This paper investigates how positional value affects transportation decisions (vehicle ownership, travel activity, location decisions, etc.), explores the resulting economic impacts, and discusses implications for transport policy and planning.
