Highway construction occurs nowadays mainly through widening of ex- isting roads rather than building new roads. This paper documents that highway widenings considerably reduce congestion in the short run, defined here as 6 years. Using longitudinal microdata from highway detector loops in the...

The paper develops a short-term space-time traffic flow forecasting strategy integrating the empirical-based seasonal autoregressive integrated moving average (SARIMA) time-series forecasting technique with the theoretical-based first-order macroscopic traffic flow model-cell transmission model....

We examine the eff ect of citywide parking policy on parking and traffic demand. Using a large increase in on-street parking prices for the city of Amsterdam, we show that the policy caused a substantial drop in on-street parking demand, which is not off set by an increase in off -street demand....

An approach to determine the demand in carrying passengers on the intercity bus route (on the example of intercity route of "Debaltsevo Sverdlovsk") is offered in the article. The approach consists of five stages: substantiation of the necessity of intercity bus route opening; determination of...

This dissertation deals with the application of Advanced Traveler Information Systems (ATIS) in incident management. Using an idealized traffic corridor and deterministic queuing methods, conditions under which route guidance information is useful are identified. Benefits to traffic guided with...

In this paper, a fuzzy traffic density homogenizer is proposed to alleviate or avoid congestion by smoothing the traffic density distribution profile over freeway lanes. The proposed fuzzy homogenizer consists of two parts: the fuzzy mean speed controller and the fuzzy on- ramp controller....

This paper presents microscopic time-space diagrams for several shock waves over 100-200m distances. The primary focus of the paper is on presenting the data rather than analysis. The diagrams should be of general interest to researchers studying traffic congestion.

The design of route-guidance systems faces a well-known dilemma. The approach that theoretically yields the system-optimal traffic pattern may discriminate against some users, for the sake of favoring others. Proposed alternate models, however, do not directly address the system perspective and...

The paper provides an overview of recent economic and social developments in Cameroon. The state and the dynamics of poverty has been analyzed. The pillars of the short- and medium-term growth and poverty reduction strategy have been described. The paper provides a quantitative assessment and...
